SIP: CLI for Caller ID When Privacy Exists

The SIP: CLI for Caller ID When Privacy Exists feature adds three command-line interface (CLI) options that make the handling of caller ID information more flexible. Specifically, the SIP: CLI for Caller ID When Privacy Exists feature addresses the following situations:

•Passing along caller ID information when privacy exists

•Handling the Display Name field when no display name exists

•Allowing caller ID information to be passed to ISDN as network-provided

Information About SIP: CLI for Caller ID When Privacy Exists

The SIP: CLI for Caller ID When Privacy Exists feature is comprised of three main components, as follows:

•SIP: Caller ID Removable to Improve Privacy

•SIP: Calling Number Substitution for the Display Name When the Display Name is Unavailable

•SIP: Calling Number Passing as Network-Provided or User-Provided

SIP: Caller ID Removable to Improve Privacy

The caller ID information is passed through from the ISDN-to-SIP by copying the number in the Calling Party Number information element (IE) in an ISDN Setup message into the Calling Number field of the SIP Remote-Party-ID and From headers.

The Calling Name from the ISDN Display IE is copied into the SIP Display Name field in the SIP Remote-Party-ID and From headers. The Calling Party Number IE contains a Presentation Indicator field that is set to presentation allowed, presentation restricted, number not available due to interworking, or reserved. Presentation allowed and presentation restricted are translated into privacy set to off or privacy set to null, respectively, in the SIP Remote-Party-ID header field.

However, for added privacy, the SIP: CLI for Caller ID When Privacy Exists feature introduces CLI to completely remove the Calling Number and Display Name from an outgoing message's From header if presentation is prohibited. This prohibits sending the SIP Remote Party ID header, because the Cisco gateway does not send SIP Remote-Party ID headers without both a Display Name and Calling Number.

Note The SIP: Caller ID Removable to Improve Privacy option is available both globally and at the dial-peer level.

See Figure 1 for call flows and Table 1 and Table 2 for additional presentation mapping.

Remote Party ID not sent


SIP: Calling Number Substitution for the Display Name When the Display Name is Unavailable

When the Display information element (IE) in a PSTN-to-SIP call is not available with a Setup message, the Cisco gateway leaves the Display Name field in the SIP Remote-Party-ID and From headers blank.

When presentation is allowed, the SIP: CLI for Caller ID When Privacy Exists feature enables the substitution of the Calling Number for the missing Display Name in the SIP Remote-Party-ID and From headers. Upon receipt of a Setup message where a name to follow is indicated, the Calling Number is not copied into the Display Name.

Also, the SIP Extensions for Caller Identity and Privacy on SIP gateway feature added the ability to hardcode calling name and number in the SIP Remote-Party-ID and From headers. The SIP Extensions for Caller Identify and Privacy feature settings take precedence over the SIP: CLI for Caller ID When Privacy Exists feature settings.

Note The SIP: Calling Number Substitutions for the Display Name When the Display Name is Unavailable option is available both globally and at the dial-peer level.

See Figure 2 for the call flow where the Calling Number is substituted for the Display Number.

Figure 2 Call Flow for Substituting the Calling Number for the Display Name When the Display Name is Unavailable

SIP: Calling Number Passing as Network-Provided or User-Provided

ISDN numbers can be passed along as network-provided or user-provided in an ISDN Calling Party information element (IE) Screening Indicator field. The Cisco gateway automatically sets the Screening Indicator to user-provided in SIP-to-ISDN calls.

The SIP: CLI for Caller ID When Privacy Exists feature allows toggling between user-provided and network-provided ISDN numbers for the screening indicator. Therefore, after bits 1 and 2 are set to reflect network-provided, any existing screening information is lost. However, presentation information in bits 6 and 7 is preserved.

Note The SIP: Calling Number Passing as Network-Provided or User-Provided option is available both globally and at the dial-peer level.

See Figure 3 for the call flow when the calling number is passed along as network-provided.

Figure 3 Call Flow for Passing Through the Calling Number as Network-Provided

How to Configure SIP: CLI for Caller ID When Privacy Exists

This section contains the following procedures:

•Configuring SIP: Blocking Caller ID Information Globally When Privacy Exists (optional)

•Configuring Dial-Peer Level SIP: Blocking of Caller ID Information When Privacy Exists (optional)

•Configuring Globally the SIP: Calling Number for Display Name Substitution When Display Name Is Unavailable (optional)

•Configuring Dial-Peer-Level SIP: Substitution of the Calling Number for Display Name When the Display Name Is Unavailable (optional)

•Configuring Globally the SIP: Pass-Through of the Passing Calling Number as Network-Provided (optional)

•Configuring at the Dial-Peer Level the SIP: Pass-Through of Passing the Calling Number as Network-Provided (optional)

•Configuring Globally the SIP: Pass-Through of the Passing Calling Number as User-Provided (optional)

•Configuring at the Dial-Peer Level the SIP: Pass-Through of Passing the Calling Number as User-Provided (optional)

Configuring SIP: Blocking Caller ID Information Globally When Privacy Exists

The Call-ID information is private information. In ISDN there is a private setting that can be set to protect this information. However, whenever SIP gets the Call-ID information, it does not hide the private information, rather, it just sets a field to reflect that it is private and not to display it on a Call-ID display. But, the data is still viewable in the SIP message requests. This option allows the Cisco gateway to delete the Call-ID information from the SIP message requests so it cannot be read on the network.

The global commands to strip the Calling Name and Calling Number from the Remote-Party-ID and From headers are as follows:

Command Reference

This section documents the following new and modified commands:

•clid (dial-peer)

•clid (voice-service-voip)

clid (dial-peer)

To control the presentation and use of calling-line ID (CLID) information, use the clid command in dial-peer configuration mode. To remove CLID controls, use the no form of this command.

clid {network-number number [second-number strip] | network-provided | overrider dnis | restrict | strip [name | pi-restrict [all]] | substitute name}

no clid {network-number number [second-number strip] | network-provided | overrider dnis | restrict | strip [name | pi-restrict [all]] | substitute name}

Syntax Description

network-number number

(Optional) Network number. Establishes the calling-party network number in the CLID for this router.

second-number strip

(Optional) Removes a previously configured second network number from the CLID.

network-provided

(Optional) Allows you to set the screening indicator to reflect the number that was provided by the network.

override rdnis

(Optional; supported for POTS dial peers only) Overrides the CLID with the redirected dialed number identification service (RDNIS) if available.

pi-restrict

(Optional) Restricted progress indicator (PI). Causes removal of the calling-party number from the CLID when the PI is restricted.

restrict

(Optional) Restricts presentation of the caller ID in the CLID.

strip

(Optional) Strips the calling-party number from the CLID.

•name—(Optional) Calling-party name. Causes removal of the calling-party name from the CLID.

•pi-restrict [all]—(Optional) Restricted PI. Causes removal of all calling-party names and numbers from the CLID when the PI is restricted.

substitute name

(Optional) Copies the calling number into the display name if PI allows it (and the calling name is empty).


Command Default

No default behavior or values

Command Modes

Command History

Release
Modification

12.2(11)T

This command was introduced.

12.2(13)T

The override rdnis keywords were added.

12.4(4)T

The following keywords were added: network-provided, pi-restrict all, and substitute name.


Usage Guidelines

The override rdnis keywords are supported only for POTS dial peers.

CLID is the collection of information about the billing telephone number from which a call originated. The CLID value might be the entire phone number, the area code, or the area code plus the local exchange. It is also known as caller ID. The various keywords to this command manage the presentation, restriction, or stripping of the various CLID elements.

The clid network-number command sets the presentation indicator to "y" and the screening indicator to "network-provided." The second-number strip keyword strips from the H.225 source-address field the original calling-party number, and is valid only if a network number was previously configured.

The clid override rdnis command overrides the CLID with the RDNIS if it is available.

The clid restrict command causes the calling-party number to be present in the information element, but the presentation indicator is set to "n" to prevent its presentation to the called party.

The clid strip command causes the calling-party number to be null in the information element, and the presentation indicator is set to "n" to prevent its presentation to the called party.

Examples

The following example sets the calling-party network number to 98765 for POTS dial peer 4321: 

Router(config)# dial-peer voice 4321 pots

Router(config-dial-peer)# clid network-number 98765

An alternative method of accomplishing this result is to enter the second-number strip keywords as part of the clid network-number command. The following example sets the calling-party network number to 56789 for VoIP dial peer 1234 and also prevents the second network number from being sent: 

Router(config)# dial-peer voice 1234 voip

Router(config-dial-peer)# clid network-number 56789 second-number strip

The following example overrides the calling-party number with RDNIS if available: 

Router(config-dial-peer)# clid override rdnis

The following example prevents the calling-party number from being presented: 

Router(config-dial-peer)# clid restrict

The following example removes the calling-party number from the CLID information and prevents the calling-party number from being presented: 

Router(config-dial-peer)# clid strip

The following example strips the name from the CLID information and prevents the name from being presented: 

Router(config-dial-peer)# clid strip name

The following example strips the calling party number when PI is set to restrict clid strip from the CLID information and prevents the calling party number from being presented: 

Router(config-dial-peer)# clid strip pi-restrict

The following example strips calling party name and number when the PI is set to the restrict all clid strip from the CLID information and prevents the calling party name and number from being presented: 

Router(config-dial-peer)# clid strip pi-restrict all

The following example substitutes the calling party number into the display name: 

Router(config-dial-peer)# clid substitute name

The following example allows you to set the screening indicator to reflect that the number was provided by the network: 

Router(config-dial-peer)# clid network-provided

Command
Description

clid (voice-service-voip)

Passes the network provided ISDN numbers in an ISDN calling party information element screening indicator field, removes the calling party name and number from the calling-line identifier in voice service voip configuration mode, or allows a presentation of the calling number by substituting for the missing Display Name field in the Remote-Party-ID and From headers.


clid (voice-service-voip)

Passes the network-provided ISDN numbers in an ISDN calling party information element screening indicator field, removes the calling party name and number from the calling-line identifier in voice service voip configuration mode, or allows a presentation of the calling number by substituting for the missing Display Name field in the Remote-Party-ID and From headers.

clid {network-provided | strip pi-restrict all | substitute name}

no {clid network-provided | strip pi-restrict all | substitute name}

Syntax Description

network-provided

Sets the screen indicator as netork-provided.

strip pi-restrict all

Removes the CLID when the progress indicator (PI) is restricted for PSTN to SIP operations and removes the calling party name and number when the PI is restricted for PSTN to SIP operations.

substitute name

Copies the calling number to the display name if unavailable for PSTN to SIP operations.


Command Default

The clid (voice-service-voip) command passes along user-provided ISDN numbers in an ISDN calling party information element screening indicator field.

Modification

12.4(4)T

This command was introduced.


Usage Guidelines

Use the clid network-provided command to pass along network-provided ISDN numbers in an ISDN calling party information element screening indicator field.

Use the clid strip pi-restrict all command to remove the Calling Party Name and Calling Party Number from the CLID.

Use the clid substitute name command to allow a presentation of the Display Name field in the Remote-Party-ID and From headers. The Calling Number is substituted for the Display Name field.

Examples

The following passes along network-provided ISDN numbers in an ISDN calling party information element screening indicator field: 

Router(config)# clid network-provided

The following passes along user-provided ISDN numbers in an ISDN calling party information element screening indicator field: 

Router(config)# no clid network-provided

The following removes the calling party name and number from the calling-line identifier (CLID): 

Router(config)# clid strip pi-restrict all

The following does not remove the calling party name and number from the CLID: 

Router(config)# no clid strip pi-restrict all

The following allows the presentation of the calling number to be substituted for the missing Display Name field in the Remote-Party-ID and From headers: 

Router(config)# clid substitute name

The following disallows the presentation of the calling number to be substituted for the missing Display Name field in the Remote-Party-ID and From headers: 

Router(config)# no clid substitute name
