mgcp persistent
To configure the sending of persistent events from the Media Gateway Control Protocol (MGCP) gateway to the call agent, use the mgcp persistentcommand in global configuration mode. To reset to the default, use the no form of this command.
mgcp persistent { hookflash | offhook | onhook }
no mgcp persistent { hookflash | offhook | onhook }
Command Default
The hookflash keyword is disabled for persistence. The offhook keyword is enabled for persistence. The onhook keyword is disabled for persistence.
Usage Guidelines
Persistent events are those events that, once they are detected, are defined as reportable to the call agent whether or not the call agent has explicitly requested to be notified of their occurrence; that is, even if they are not included in the list of RequestedEvents that the gateway is asked to detect and report. Such events can include fax tones, continuity tones, and on-hook transition. Each event has an associated action for the gateway to take.
Use this command for each type of persistent event that should override the default behavior.
mgcp piggyback message
To enable piggyback messages, use the mgcp piggyback messagecommand in global configuration mode. To disable piggyback messages, use the no form of this command.
Usage Guidelines
If the network gateway cannot handle piggyback messages, us e the no form of this command to disable the piggyback messages and to enable Media Gateway Control Protocol (MGCP) 1.0, Network-based Call Signaling (NCS), and Trunking Gateway Control Protocol (TGCP). Piggyback messaging is not available to Simple Gateway Control Protocol (SGCP) and MGCP 0.1.
The term piggyback message refers to a situation in which a gateway or a call agent sends more than one MGCP message in the same User Datagram Protocol (UDP) packets. The recipient processes the messages individually, in the order received. However, if a message must be retransmitted, the entire datagram is resent. The recipient must be capable of sorting out the messages and keeping track of which messages have been handled or acknowledged.
Piggybacking is used during retransmission of a message to send previously unacknowledged messages to the call agent. This maintains the order of events the call agent receives and makes sure that RestartInProgress (RSIP) messages are always received first by a call agent.
mgcp playout
To tune the jitter-buffer packet size attempted for MGCP-controlled connections, use the mgcp playout command in global configuration mode. To reset to the default, use the no form of this command.
mgcp playout { adaptive init-milliseconds min-milliseconds max-milliseconds | fax milliseconds | fixed milliseconds [no-timestamps] }
no mgcp playout { adaptive | fax | fixed }

12.4(24)T3
The maximum number of MGCP profiles that can be configured was increased from 13 (12 plus 1 default) to 29 (28 plus 1 default).
Usage Guidelines
An MGCP profile is a subset of endpoints on a media gateway. More than one MGCP profile can be configured on a gateway at the same time. Prior to Cisco IOS Release 12.2(24)T3, the maximum number of MGCP profiles was 13 (12 plus 1 default). Beginning in Cisco IOS Release 12.2(24)T3, the maximum number of MGCP profiles is 29 (28 plus 1 default). The voice-port command in MGCP profile configuration mode associates endpoints with the profile.
There are two types of MGCP parameters: global and profile-related. The parameters that are configured in MGCP profile configuration mode are the profile-related parameters. However, endpoints do not need to belong to an MGCP profile. When endpoints are not associated with any MGCP profile, values for the profile-related MGCP parameters are provided by a default profile . Although all of the parameters for the default profile have default values, they can also be configured in the same way that an MGCP profile is configured by simply using the default keyword instead of a profile name. The main difference between a default profile and a user-defined profile is that there is no voice-port or call-agent association in the default profile, but they are required in user-defined profiles. When configuring the default profile, do not use the call-agent command or the voice-port command.
This command initiates MGCP profile configuration mode, in which you create an MGCP profile for an endpoint or a set of endpoints on a media gateway, and you set parameters for that profile or for the default profile.
Examples
The following example shows the definition of the MGCP profile named newyork:
Router(config)# mgcp profile newyork Router(config-mgcp-profile)# call-agent 10.14.2.200 4000 service-type mgcp version 1.0 Router(config-mgcp-profile)# voice-port 0:1 Router(config-mgcp-profile)# package persistent mt-package Router(config-mgcp-profile)# timeout tsmax 100 Router(config-mgcp-profile)# timeout tdinit 30 Router(config-mgcp-profile)# timeout tcrit 600 Router(config-mgcp-profile)# timeout tpar 600 Router(config-mgcp-profile)# timeout thist 60 Router(config-mgcp-profile)# timeout tone mwi 600 Router(config-mgcp-profile)# timeout tone ringback 600 Router(config-mgcp-profile)# timeout tone ringback connection 600 Router(config-mgcp-profile)# timeout tone network congestion 600 Router(config-mgcp-profile)# timeout tone busy 600 Router(config-mgcp-profile)# timeout tone dial 600 Router(config-mgcp-profile)# timeout tone dial stutter 600 Router(config-mgcp-profile)# timeout tone ringing 600 Router(config-mgcp-profile)# timeout tone ringing distinctive 600 Router(config-mgcp-profile)# timeout tone reorder 600 Router(config-mgcp-profile)# timeout tone cot1 600 Router(config-mgcp-profile)# timeout tone cot2 600 Router(config-mgcp-profile)# max1 retries 10 Router(config-mgcp-profile)# no max2 lookup Router(config-mgcp-profile)# max2 retries 10 Router(config-mgcp-profile)# exitmgcp quality-threshold
To set the jitter buffer size threshold, latency threshold, and packet-loss threshold parameters, use the mgcp quality-threshold command in global configuration mode. To reset to the defaults, use the no form of this command.
mgcp quality-threshold { hwm-cell-loss value | hwm-jitter-buffer value | hwm-latency value | hwm-packet-loss value | lwm-cell-loss value | lwm-jitter-buffer value | lwm-latency value | lwm-packet-loss value }

12.2(11)T
This command was implemented on the Cisco AS5850.
Usage Guidelines
The following impact the quality of voice calls:
- Cell loss (the number of ATM cells lost during transmission)
- Jitter buffer (storage area containing active call voice packets that have been received from the network and are waiting to be decoded and played)
- Latency (network delay in sending and receiving packets)
- Packet loss (number of packets lost per 100,000 packets for a given call)
For good voice quality, the system should perform below the low water mark values. As the values go higher, voice quality degrades. The system generates a report when the values go above the high water marks levels. Set the high water marksand low water marks values sufficiently apart so that you receive reports on poor performance, but not so close together that you receive too much feedback.
Enter each parameter as a separate command.
mgcp quarantine mode
To configure the mode for Media Gateway Control Protocol (MGCP) quarantined events, use the mgcp quarantine modecommand inglobal configuration mode. To reset to the default, use the noform of this command.
Syntax Description
discard
Enables discarding of quarantined events instead of processing. Observed events are not reported to the call agent, even if the call agent is ready to receive them.
loop
Enables loop mode for quarantined events instead of stepping. After receiving a request from the call agent, the gateway reports the observed events to the call agent in multiples without waiting for subsequent requests.
process
Enables processing of quarantined events instead of discarding. Observed events are reported to the call agent when the call agent is ready to receive them.
step
Enables step mode for quarantined events instead of looping. After receiving a request from the call agent, the gateway reports observed events individually to the call agent, one for each request.

This command was integrated into Cisco IOS Release 12.2(4)T.
12.2(11)T
This command was implemented on the Cisco AS5300 and Cisco AS5850.
Usage Guidelines
Quarantine events are defined as events that have been detected by the gateway before the arrival of the MGCP NotificationRequest command but that have not yet been notified to the call agent. They are held in the quarantine buffer until receipt of the MGCP NotificationRequest command, when the gateway is expected to generate either one notification (step by step) or multiple notifications (loop) in response to this request (the default is exactly one), based on the configuration of the mgcp quarantine mode command.
This command supports backward compatibility with SGCP implementations running under the MGCP application. SGCP does not have a way to allow the call agent to control the quarantine mode. MGCP has this functionality.
When the gateway is in the notification state, the interdigit timer (Tcrit) is not started.
When the gateway receives an unsuccessful NotificationRequest, the current RequestEventList and SignalEventList are emptied. The ObservedEventList and quarantine buffer are also emptied.
Changes to the quarantine mode only take effect when the gateway is rebooted or the MGCP application is restarted.
Examples
The following example starts the MGCP application:
Router(config)# mgcpThe following example stops the MGCP application:
Router(config)# no mgcpThe following example turns on processing of quarantined events and sends observed events to the call agent:
Router(config)# mgcp quarantine mode processThe following example turns off processing of quarantined events:
Router(config)# no mgcp quarantine mode discardThe following example sends observed events to the call agent in loop mode:
Router(config)# mgcp quarantine mode process loopmgcp quarantine persistent-event disable
To disable handling of persistent call events in the Media Gateway Control Protocol (MGCP) quarantine buffer, use the mgcp quarantine persistent-events disable command in global configuration mode. To reset to the default state, use the no form of this command.

Usage Guidelines
This command enables the reporting of persistent events immediately to the call agent rather than holding the events in quarantine. Persistent events are events defined as reportable whether or not the call agent explicitly has requested to be notified of their occurrence. Quarantining means that the gateway observes events but does not report them to the call agent until the call agent indicates readiness to receive notifications. By default, all events, including persistent events, are quarantined when they are detected, even when the gateway is in a notification state. When the mgcp quarantine persistent-event disable command is configured, however, persistent events are reported to the call agent immediately by an MGCP Notify command.
mgcp request timeout
To specify how long a Media Gateway Control Protocol (MGCP) gateway waits for a call-agent response to a request before retransmitting the request, use the mgcp request timeout command in global configuration mode. To reset to the default, use the no form of this command.

The cisco-codec-fax-ackand cisco-codec-fax-indkeywords were added.
12.4(13f)
The cisco-codec-fax-ackand cisco-codec-fax-indkeywords were added.
Usage Guidelines
Cisco IOS Release 12.2(11)T introduced an RTP payload type negotiation for MGCP VoIP calls different from previous Cisco IOS images. To ensure interoperability between gateways using different Cisco IOS images, follow these guidelines:
- For fax and modem codecs--If either the originating or terminating MGCP gateway is running Cisco IOS Release 12.2(11)T or a later release and the other gateway is running a release earlier than Cisco IOS Release 12.2(11)T, use the mgcp rtp payload-type command on the gateway with the later release.
- For voice codecs--If you are using a Clear Channel, G.726R16, or G.726R24 codec, and either the originating or terminating MGCP gateway is running Cisco IOS Release 12.2(11)T or a later release and the other gateway is running a release earlier than Cisco IOS Release 12.2(11)T, use the mgcp rtp payload-typecommand on the gateway with the later release.
If both the originating and terminating gateways are using Cisco IOS Release 12.2(11)T or a later release, this command is not required.
The cisco-codec-fax-ackand cisco-codec-fax-indkeywords are used to change the default dynamic payload type for the Cisco fax relay feature to a different dynamic payload type.
NoteNSE and NTE cannot be configured to use the same value. An error message will be generated by the command parser if the same value is entered.
Examples
The following example specifies use of dynamic RTP payload type for fax and modem calls for mu-law pulse code modulation (PCM) calls in an MGCP network in which the other gateway is running a release of Cisco IOS software that is earlier than Release 12.2(11)T:
Router# mgcp rtp payload-type cisco-pcm-switch-over-ulaw 126The following example specifies use of a static RTP payload type for a G.726R16 codec in an MGCP network in which the other gateway is running a release of Cisco IOS software that is earlier than Release 12.2(11)T:
Router# mgcp rtp payload-type g726r16 staticThe following examples configure the gateway to use RTP payload 104 for NSE events and payload 108 for NTE events. These payload types are used when the gateway is advertising capabilities via the Session Definition Protocol (SDP). If the gateway is recieving the SDP, the payload types configured in the remote SDP will be used instead.
Router# mgcp rtp payload-type nse 104 Router# mgcp rtp payload-type nte 108mgcp rtp unreachable timeout
To enable detection of an unreachable remote VoIP endpoint, use the mgcp rtp unreachable timeoutcommand in global configuration mode. To disable detection, use the noform of this command.
Usage Guidelines
Thiscommand is useful for preventing calls from remaining open when the remote endpoint is no longer available.
For example, suppose an IP phone makes a call through a gateway to another IP phone. During the call, the call agent goes down and the remote IP phone hangs up. Normally, the call agent would tell the gateway to tear down the call. In this case, the gateway continues to treat the call as active and sends more voice packets to the remote IP phone. The remote IP phone returns Internet Control Message Protocol (ICMP) port unreachable messages to the gateway. If the mgcp rtp unreachable timeout command is enabled, the gateway tears down the call. If the command is disabled, the call is left open.
The timer-value argument tells the gateway how long to wait before tearing down the call. After receiving the ICMP the unreachable message, the gateway starts a timer. If the gateway does not receive any voice packets by the end of the timer-value period, the gateway tears down the call. If some voice packets arrive before the end of the timer-value period, the gateway resets the timer and leaves the call in active state.
mgcp rtrcac
mgcp sched-time
To configure the scheduled timer value for Media Gateway Control Protocol (MGCP), use the mgcp sched-time command in global configuration mode. To disable the configuration, use the no form of this command.
Usage Guidelines
The mgcp sched-time command is used to configure the MGCP process a specified time to run before it yields to a process of a lower or the same priority. The schedule timer value must be from 12 to 40 ms, the minimum and maximum time, respectively, a process can run. This ensures that the MGCP process is not suspending too often.
mgcp sdp
To specify parameters for Session Definition Protocol (SDP) operation in Media Gateway Control Protocol (MGCP), use the mgcp sdpcommand inglobal configuration mode. To disable the parameters, use the no form of this command.
mgcp sdp { notation undotted | simple | xpc-codec }
no mgcp sdp { notation undotted | simple | xpc-codec }
Syntax Description
notation undotted
Enables undotted SDP notation for the codec string in SDP.
simple
Enables simple mode of SDP operation for MGCP.
xpc -codec
Enables initial generation of the X-pc-codec field, which is used during codec negotiation in SDP for Network-based Call Signaling (NCS) and Trunking Gateway Control Protocol (TGCP).

12.2(4)T
This command was integrated into Cisco IOS Release 12.2(4)T.
12.2(11)T
This command was implemented on the Cisco AS5300 and Cisco AS5850.
Usage Guidelines
This command allows you to configure SDP fields to meet the requirements of your call agent.
The notation undottedkeyword is for the G.726-16 and G.729 codecs. The codec strings G.726-16 and G.729 are dotted notation. The codec notation format is selected dynamically in the following order of preference:
- The notation used in SDP for MGCP packets from the call agent.
- The notation used in the a: parameter of the Local connection option for MGCP packets from the call agent.
- The notation set by the mgcp sdp notation undotted command.
The simple keyword, when enabled, causes the gateway not to generate the following SDP fields: o (origin and session identifier), s (session name), and t (session start time and stop time). Certain call agents require this modified SDP to send data through the network.
The xpc-codec keyword, in TGCP and NCS, defines a new field (X-pc-codec) in the SDP for codec negotiation. To be backward compatible with nonpacket-cable SDPs, the initial generation of the X-pc-codec field is suppressed by default. However, if a received SDP contains this field, the X-pc-codec field is read and generated in response to continue with the codec negotiation.
mgcp sgcp disconnect notify
To enable enhanced endpoint synchronization after a disconnected procedure in a Simple Gateway Control Protocol (SGCP) version 1.5 network, use the mgcp sgcp disconnect notify command in global configuration mode. To disable this feature, use the no form of this command.
Usage Guidelines
This command is used with SGCP version 1.5 to provide enhanced messaging capability for an endpoint that undergoes the disconnected procedure. It does not apply to gateways that run Media Control Gateway Protocol (MGCP) or other versions of SGCP.
An SGCP endpoint may lose communication with its call agent because the call agent is temporarily off line or because of faults in the network. When a gateway recognizes that an endpoint has lost its communication with the call agent (has become disconnected), it attempts to restore contact. If contact is not established before the disconnected timer expires, the disconnected procedure is initiated.
The disconnected procedure consists of the endpoint sending a Restart In Progress (RSIP) message to the call agent, stating that the endpoint was disconnected and is now trying to reestablish connectivity. If the mgcp sgcp disconnect notify command has been configured on the gateway, a special disconnected RSIP message is sent. When contact is reestablished, the call agent may decide to audit the endpoint using an Audit Endpoint (AUEP) command with additional I, ES, and RM parameters, which are defined as follows:
- I--List of connection identifiers for current connections on the endpoint
- ES--Event state of the endpoint (off-hook or on-hook)
- RM--Restart method reason for the last RSIP (graceful, forced, restart, or disconnected)
Endpoint synchronization with the call agent is achieved by the exchange of the disconnected RSIP message and the endpoint audit.
mgcp sgcp restart notify
To trigger the Media Gateway Control Protocol (MGCP) application to process Simple Gateway Control Protocol (SGCP)-type restart in progress (RSIP) messages, use the mgcp sgcp restart notifycommand in global configuration mode. To cancel the trigger, use the noform of this command.

Usage Guidelines
Use this command to specify the RTP Control Protocol (RTCP) transmission interval for VoIP calls and the continuity-test timeout interval for VoIP and VoATM adaptation layer 2 (VoAAL2) calls.
The receive-rtcpkeyword is the timer used by a gateway to disconnect a VoIP call when IP connectivity is lost with the remote gateway. After receiving each RTP or RTCP packet from the remote gateway, the receiving gateway starts a timer. The period of the timer is determined by multiplying the value configured using the mgcp timer receive-rtcpcommand with the value configured using ip rtcp report interval command. If the timer expires before the next packet is received from the remote gateway, the receiving gateway disconnects the call and notifies the call agent.
The net -cont-test keyword uses the terminating gateway to verify the network connectivity with the originating gateway before ringing the called party. To do this, the terminating gateway sends a command packet to the originating gateway and starts a timed for the timerperiod. If the timer expires before any acknowledgement from the originating gateway is received, the terminating gateway does not ring the called party, but instead disconnects the call and alerts the call agent.
The nse-response t38option sets the timer for awaiting T.38 NSE responses. This timer is configured to tell the terminating gateway how long to wait for an NSE from a peer gateway. The NSE from the peer gateway can either acknowledge the switch and its readiness to accept packets or indicate that it cannot accept T.38 packets.
Examples
The following example sets the multiplication factor to 10 (or x*10, where x is the interval that is set with the ip rtcp report interval command):
Router(config)# mgcp timer receive-rtcp 10The following example sets the net-cont-test timer to 1500 ms (1.5 seconds):
Router(config)# mgcp timer net-cont-test 1500The following example enables MGCP fax relay and sets the gateway wait time to 300 ms for an NSE from a peer gateway:

mgcp validate call-agent source-ipaddr
To enable the Media Gateway Control Protocol (MGCP) application to validate that packets are received from a configured call agent, use the mgcp validate call-agentsource-ipaddr command in global configuration mode. To disable the validation feature, use the no form of this command.
Usage Guidelines
This command verifies that incoming packets are received from MGCP or Cisco CallManager configured call agents only. When the command is enabled, all MGCP messages received from call agents that are not configured in MGCP or Cisco CallManager are dropped. Use the mgcp validate call-agent source-ipaddr command in place of access lists to filter out packets from unconfigured call agents. Use the mgcp bind control source-interface interfacecommand to restrict the MGCP application from responding to unconfigured call agent requests on nonsecure interfaces. Use the ccm-manager config server server address command to configure the Cisco CallManager address to be used when verifying incoming packets.
Examples
The following example shows that MGCP call-agent validation is enabled:
Router(config)# mgcp validate call-agent source-ipaddrRelated Commands

12.4(2)T2; 12.4(4)T1; 12.4(6)T
The default state of this command was changed to disabled.
Usage Guidelines
The mgcp validate domain-name command enables validation of a hostname and domain (or specific IP address) received as part of the endpoint name sent from the call agent (CA) or Cisco CallManager against those configured on the gateway. If the hostname or domain (or IP address) is not valid, the system returns a 500 error with appropriate comment.
Use the mgcp validate domain-name command before configuring MGCP globally in a VoIP network. (See the Cisco Unified CallManager and Cisco IOS Interoperability Guide for global MGCP configuration information.)
NoteOnly MGCP messages received from the CA or Cisco CallManager are validated .
You can display the current setting for MGCP domain name validation using the show running-config command. To show only MGCP information, limit the display output to the section on MGCP (see the "Examples" section).
NoteWhen MGCP domain name validation is disabled, the output of the show running-config command does not include this command--it displays only when domain name validation is enabled. However, if your system is running a software image released before the default for this feature was changed, MGCP domain name validation is turned on by default and will appear in the show running-config command output only if validation is disabled.
Once you enable the MGCP validate domain name feature, you should verify that the appropriate endpoint name is included as part of incoming MGCP messages. Performing this verification helps to ensure that incoming messages with invalid hostnames, domain names, and IP addresses are rejected while valid incoming messages are still allowed to reach their target endpoint (host). Enabling this validation feature without verifying this information can cause all incoming messages, even those using valid names or addresses, to be rejected (see the "Examples" section).
Examples
The following examples show how to enable MGCP domain name validation, how to verify that validation is enabled in the running configuration, and how to verify and match the hostname, domain name, or IP address specified in incoming MGCP messages to the gateway configuration.
Use the following command to enable MGCP domain name validation:
Router(config)# mgcp validate domain-nameUse the following command to verify that MGCP domain name validation is enabled:
Router(config)# show running-config | section mgcpor
Router(config)# show running-config | include mgcp validate mgcp validate domain-name Router(config)#Use the following commands and processes to verify that hostname and domain name are configured so that all and only valid incoming messages are accepted by the gateway.
After enabling domain name validation, enable debug tracing for MGCP packets:
Router# debug mgcp packets Media Gateway Control Protocol packets debugging for all endpoints is on Router#Generate a call to the gateway from a CA or Cisco CallManager. That call will generate debug messages on the gateway so that you can view the endpoint information included in the incoming MGCP message and the response from the gateway to the CA (or Cisco CallManager):

mgcp voice-quality-stats
To enable voice-quality statistics reporting for the Media Gateway Control Protocol (MGCP), use the mgcp voice-quality-stats command in global configuration mode. To turn off voice-quality statistics reporting, use the no form of this command.
mgcp voice-quality-stats [ priority variable | all ]
no mgcp voice-quality-stats [ priority variable | all ]
Usage Guidelines
- The request for digital signal processor (DSP) statistics is controlled by the RTP Control Protocol (RTCP) statistics polling interval. The polling interval is configurable by entering the ip rtcp report interval command. Statistics are polled every 5 seconds by default.
NoteThe Cisco PGW 2200 must have a patch the supports DSP statistics in order to collect data in the call detail records (CDRs).
- This command does not generate any output on the console; it adds additional quality statistics parameters in the MGCP Delete Connection (DLCX) ACK message that is sent to the call agent.
Cisco IOS Release 12.4(4)T supports only priority levels 1 and 2.
NoteChoosing priority 2 is similar to using the keyword all where all the paramters are selected.
The corresponding set of VQ parameters are sent in the MGCP DLCX message based on the priority selected.
Examples
The following example enables voice-quality statistics reporting for MGCP:
Router> enable Router# configure terminal Router(config)# mgcp voice-quality-stats Router(config)# endThe following example shows the VQ parameters selected for priority 1:

Usage Guidelines
The midcall-signaling command distinguishes between the way Cisco Unified Communications Express and Cisco Unified Border Element handle signaling messages. Most SIP-to-SIP video and SIP-to-SIP reinvite based supplementary services require the midcall-signaling command to be configured before configuring other supplementary services. Supplementary service features that are functional without configuring midcall-signaling include: session refresh, fax, and refer-based supplementary services. The midcall-signaling command is for SIP-to-SIP calls only. All other calls (H323-to-SIP, and H323-to-H323) do not require the midcall-signalingcommand be configured. The allow-connections sip-to-sip command must be configured before the midcall-signaling command.
Configuring the Session Refresh with Reinvites feature on a dial-peer basis is not supported.
Examples
The following example shows SIP messages configured to passthrough from one IP leg to another IP leg:

Usage Guidelines
A proxy, user-agent client, and user-agent server can all have a configured minimum value indicating the smallest session interval that they accept. If they all happen to have a different configured minimum value, the highest minimum value is used. This command sets the minimum timer that is conveyed in the Min-SE header in the initial INVITE request.
The recommended value for this command is 1800 seconds (30 minutes), which is the default value. The value cannot be set below 90 seconds because excessive INVITEs create problems for routers. Once set, the value affects all calls originated by the router.
If you do not configure the session expires interval and configure only the min-se value then the session expires interval takes the value that is configured for the min-se.

To remove the definition of the account identification source, use the no form of this command.
mmoip aaa receive-id primary { ani | dnis | gateway | redialer-id | redialer-dnis }
no mmoip aaa receive-id primary { ani | dnis | gateway | redialer-id | redialer-dnis }
Syntax Description
ani
AAA uses the calling party telephone number (automatic number identification [ANI]) as the AAA account identifier.
dnis
AAA uses the called party telephone number (dialed number identification service [DNIS]) as the AAA account identifier.
gateway
AAA uses the router-specific name derived from the hostname and domain name as the AAA account identifier, displayed in the following format: router-name.domain-name.
redialer -id
AAA uses the account string returned by the external redialer device as the AAA account identifier. In this case, the redialer ID is either the redialer serial number or the redialer account number.
redialer -dnis
AAA uses the called party telephone number (dialed number identification service [DNIS]) as the AAA account identifier that is captured by the redialer if a redialer device is present.

Usage Guidelines
Normally, when AAA is being used for simple user authentication, AAA uses the username information defined in the user profile for authentication. With store-and-forward fax, you can specify that the ANI, DNIS, gateway ID, redialer ID, or redialer DNIS be used to identify the user for authentication. This command defines what AAA uses for the primary identifier for inbound or on-ramp user authentication with store-and-forward fax.
Store-and-forward fax allows you to define either a primary or a secondary identifier. You configure the secondary identifier using the mmoip aaa receive-id secondary command.
AAA does not use these methods sequentially. If the primary identifier is defined and AAA cannot authenticate the primary identifier information, it does not use the secondary identifier for authentication. Authentication simply fails.
Defining only the secondary identifier enables you to service two different scenarios simultaneously--for example, if you are offering fax services to two different companies, one of which uses redialers and the other does not. In this case, configure the mmoip aaa receive-id primary command to use the redialer DNIS, and configure the mmoip aaa receive-id secondary command to use ANI. With this configuration, when a user dials in and the redialer DNIS is not null, the redialer DNIS is used as the authentication identifier. If a user dials in and the redialer DNIS is null, ANI is used as the authentication identifier.
This command applies to on-ramp store-and-forward fax functions.
mmoip aaa receive-id secondary
To specify the secondary location where the authentication, authorization, and accounting (AAA) protocol retrieves its account identification information for on-ramp faxing if the primary identifier has not been defined, use the mmoip aaa receive-id secondary command in global configuration mode. To remove the definition of the account identification source, use the no form of this command.
mmoip aaa receive-id secondary { ani | dnis | gateway | redialer-id | redialer-dnis }
no mmoip aaa receive-id secondary { ani | dnis | gateway | redialer-id | redialer-dnis }
Syntax Description
ani
AAA uses the calling party telephone number (automatic number identification or ANI) as the AAA account identifier.
dnis
AAA uses the called party telephone number (dialed number identification service or DNIS) as the AAA account identifier.
gateway
AAA uses the router-specific name derived from the host name and domain name as the AAA account identifier, displayed in the following format: router-name.domain-name.

With this configuration, when a user dials in and the redialer DNIS is not null, the redialer DNIS is used as the authentication identifier. If a user dials in and the redialer DNIS is null, ANI is used as the authentication identifier.
This command applies to on-ramp store-and-forward fax functions.
mmoip aaa send-accounting enable
To enable off-ramp authentication, authorization, and accounting (AAA) services, use the mmoip aaa send-accounting enablecommand in global configuration mode. To reset to the default, use the no form of this command.
Usage Guidelines
This command enables AAA services if an AAA method list has been defined using both the aaa accounting command and the mmoip aaa method fax accounting command.
This command applies to off-ramp store-and-forward fax functions when using a modem card. It is not used with voice feature cards.
Examples
The following example specifies an AAA method list (called xyz) to be used with outbound store-and-forward fax. In this example, store-and-forward fax is configured to track start and stop connection accounting records.
aaa new-model mmoip aaa method fax accounting xyz aaa accounting connection sherman stop-only radius mmoip aaa send-accounting enablemmoip aaa send-authentication enable
To enable off-ramp authentication, authorization, and accounting (AAA) services, use the mmoip aaa send-authentication enablecommand in global configuration mode. To disable off-ramp AAA services, use the no form of this command.
Usage Guidelines
This command enables AAA services if an AAA method list has been defined using both the aaa authentication command and the mmoip aaa method fax authentication command.
This command applies to off-ramp store-and-forward fax functions.
Examples
The following example specifies an AAA method list (called xyz) to be used with outbound store-and-forward fax. In this example, RADIUS authentication (and if the RADIUS server fails, then local authentication) is configured for store-and-forward fax.
aaa new-model mmoip aaa method fax authentication xyz aaa authentication login peabody radius local mmoip aaa send-authentication enablemmoip aaa send-id primary
To specify the primary location where the authentication, authorization, and accounting (AAA) protocol retrieves its account identification information for off-ramp faxing, use the mmoip aaa send-id primary command in global configuration mode. To remove the definition of the account identification source, use the no form of this command.
mmoip aaa send-id primary { account-id | envelope-from | envelope-to | gateway }
no mmoip aaa send-id primary { account-id | envelope-from | envelope-to | gateway }
Syntax Description
account -id
AAA uses the account username from the originating fax-mail system as the AAA account identifier. This means that the off-ramp gateway uses the account identifier in the X-account ID field of the e-mail header. Using this attribute offers end-to-end authentication and accounting tracking.
envelope -from
AAA uses the account username from the fax-mail header as the AAA account identifier.
envelope -to
AAA uses the recipient derived from the fax-mail header as the AAA account identifier.
gateway
AAA uses the router-specific name derived from the host name and domain name as the AAA account identifier, displayed in the following format: router-name.domain-name.
Usage Guidelines
Normally, when AAA is being used for simple user authentication, AAA uses the username information defined in the user profile for authentication. With store-and-forward fax, you can specify that the account ID, username, or recipient name from the e-mail header information be used to identify the user for authentication. This command defines what AAA uses for the primary identifier for outbound or off-ramp user authentication with store-and-forward fax.
Store-and-forward fax allows you to define either a primary or a secondary identifier. You configure the secondary identifier using the mmoip aaa send-id secondary command. AAA extracts the authentication identifier information from the defined sources. If the field is blank (meaning undefined), AAA uses the secondary identifier source if configured. The secondary identifier is used only when the primary identifier is null. In this case, when AAA sees that the primary identifier is null, it checks to see if a secondary identifier has been defined and use that value for user authentication.
AAA does not use these methods sequentially--meaning that if the primary identifier is defined and AAA cannot authenticate the primary identifier information, it does not use the secondary identifier for authentication. Authentication simply fails.
When you enable authentication, the on-ramp gateway inserts whatever value you configure for the mmoip aaa receive-id primary command in the X-account ID field of the e-mail header. This X-account ID field contains the value that is used for authentication and accounting by the on-ramp gateway. For example, if the mmoip aaa receive-id primary command is set to gateway, the on-ramp gateway name (for example, hostname.domain-name) is inserted in the X-account ID field of the e-mail header of the fax-mail message.
If you want to use this configured gateway value in the X-account ID field, you must configure the mmoip aaa send-id primary command with the account-id keyword. This particular keyword enables store-and-forward fax to generate end-to-end authentication and accounting tracking records. If you do not enable authentication on the on-ramp gateway, the X-account ID field is left blank.
This command applies to off-ramp store-and-forward fax functions.
