Cisco IPICS provides the Cisco IPICS service, which allows several Cisco Unified IP Phone models to communicate on PTT channels and participate in channels and VTGs.

Before a user can access the Cisco IPICS service, Cisco IPICS must be configured as a phone service for Cisco Unified CallManager or for Cisco Unified CallManager Express. In addition, users in a deployment that includes Cisco Unified CallManager must subscribe to the Cisco IPICS service by using the Cisco Unified CallManager User Options application.

The total number of Cisco Unified IP Phones, LMR and multicast ports, PMC clients, dial users, and ops views cannot exceed the number that is specified in your Cisco IPICS license. For more information about licenses, see the "Managing Licenses" section.

Subscribing to the Cisco IPICS Service

Cisco Unified IP Phone users in a deployment that includes Cisco Unified CallManager must subscribe to the Cisco IPICS service before they can access the service from a phone.

The information in this section does not apply to users in a deployment that includes Cisco Unified CallManager Express. Cisco Unified CallManager Express supports one active service and users are subscribed to that service automatically.

Before a user can subscribe to the Cisco IPICS service, the service must be configured as described in the "Configuring Cisco IPICS as a Phone Service for Cisco Unified CallManager" section.

To subscribe to the Cisco IPICS service, perform the following procedure:

Procedure

---

Step 1 Log in to the Cisco Unified CallManager User Options web site.

For more information about accessing the Cisco Unified CallManager User Options web site, and for additional information about the phone features for your phone model, refer to the Cisco Unified IP Phone documentation at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/voice/c_ipphon/index.htm

Step 2 From the Cisco Unified CallManager User Options Menu, choose your device type or profile from the drop-down list.

Step 3 From the Cisco Unified CallManager User Options Menu, choose Configure your Cisco IP Phone Services.

Cisco Unified CallManager displays a list of subscribed services and allows you to choose from a list of available services.

Step 4 Choose the Cisco IPICS service from the Available Services drop-down list, then click Continue.

Step 5 To subscribe to the Cisco IPICS service, click Subscribe.

The information that is configured in Cisco Unified CallManager Administration, such as the service description, the IP address of the Cisco IPICS server, and the path to the service, displays in this window.

Step 6 Click Log Off.

Using the Cisco IPICS Service on a Cisco Unified IP Phone

This section describes how to use the Cisco IPICS service from a Cisco Unified IP Phone. Before a user can access the Cisco IPICS service from a Cisco IP Phone, the prerequisites that are described in Table B-1 must be met:

Table B-1 Prerequisites for Using the Cisco IPICS Service

Prerequisite	Reference
Cisco IPICS service must be configured.	See the "Configuring Cisco IPICS as a Phone Service for Cisco Unified CallManager" section or the "Configuring Cisco IPICS as a Phone Service for Cisco Unified CallManager Express" section.
Login credentials must be configured for the user.	A Cisco IPICS user can configure personal login credentials as described in the "Managing Your User Profile" section. A Cisco IPICS operator can configure login credentials for a user as described in the "Managing Dial Login Information for a User" section.
Users in a Cisco Unified CallManager environment must subscribe to the Cisco IPICS service.	See the "Subscribing to the Cisco IPICS Service" section.

In addition, users should be aware of the following guidelines:

•To obtain help with using the Cisco IPICS service on a Cisco Unified IP Phone, press the Help softkey.

•Channels returned from Cisco IPICS to a Cisco Unified IP Phone must have a multicast connection defined in the Default Location field in the Dial Login tab for the user. (For more information about this tab, see the "Managing Dial Login Information for a User" section.) Channels that do not meet this requirement do not display on the phone.

•A Cisco Unified IP Phone receives a list composed of associated channels in alphabetized order, followed by a list of associated VTGs in alphabetical order.

•A Cisco Unified IP Phone does not receive direct two-way channels or direct dial channels because these channels require SIP unicast connections.

•A phone that is logged into the Cisco IPICS service logs out automatically after 30 minutes of inactivity.

•A Cisco IPICS user can be logged in to the Cisco IPICS service with the same login credentials on two or more phones simultaneously. In this case, the following information applies:

–The user can send and receive audio on all of the phones.

–If the user presses a key on any phone that causes the phone to interact with the server (for example, the Back, Latch, or Help softkey), all phones log out except the last one that was logged into.

•If a phone loses connectivity to the Cisco IPICS server while the phone user is logged in to the Cisco IPICS service, the service retains its current state and the user can continue to use the PTT functionality for the channel or VTG that is currently selected. However, the phone cannot connect to other channels or VTGs until connectivity to the server is re-established.

•When the Cisco Unified Wireless IP Phone 7921 is connected to an active Cisco IPICS channel or VTG, the phone goes into continuous listening mode. In this mode, the phone remains in an active receive state even if Cisco IPICS is not transmitting audio. In this state, the phone continues to draw power from the battery, which limits the battery life to approximately eight hours of talk time. (When the channel or VTG is deactivated, the phone enters standby mode to conserve power.) To ensure that you have adequate an power supply for your Cisco Unified Wireless IP Phone 7921, Cisco recommends that you maintain a backup battery for use with your phone. For more information about the Cisco Unified Wireless IP Phone 7921, refer to the Cisco Unified IP Phone documentation that is available at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/voice/c_ipphon/english/
index.htm

•You can customize the softkeys on the Cisco Unified Wireless IP Phone 7920/7921 to enable direct access to the Services menu. For details, refer to the Cisco Unified CallManager documentation at this URL:

http://www.cisco.com/univercd/cc/td/doc/product/voice/c_callmg/

•The PTT button on the Cisco Unified Wireless IP Phone 7921 does not require any special configuration. A user can use either this button or the PTT softkey to communicate in a VTG or a channel. The PTT button cannot be used to latch a channel. To latch a channel, you must press the Latch softkey.

To access the Cisco IPICS service from a Cisco Unified IP Phone, perform the following procedure:

Procedure

---

Step 1 Access the Services menu on the phone.

The procedure for accessing the Service menu varies by phone model. Refer to your Cisco IP Phone documentation for specific instructions.

Step 2 Choose the Cisco IPICS service, then press the Select softkey.

Step 3 Enter your digit ID and digit password (PIN), then press the Submit softkey.

Cisco IPICS displays the list of channels and VTGs that have been assigned to you and activated for your use.

The Cisco IPICS operator configures the digit ID and digit password (PIN). For more information, see the "Managing Dial Login Information for a User" section.

Step 4 Press the Update softkey to receive any new channels and VTGs.

The channels and VTGs that display in the menu are those that are available when the Cisco IPICS service starts. To view an updated list of channels, you must press the Update softkey. The Cisco IPICS server does not automatically download channel or VTG information to the phone until you press this softkey.

Step 5 To participate in a channel or VTG, use the Navigation button to scroll to the channel or VTG in which you want to participate, then press the Select softkey.

When you choose a channel or VTG, it becomes active on your Cisco Unified IP Phone.

Step 6 To talk on the channel or VTG, press and hold the PTT softkey.

If you want to latch, or lock in, the channel or VTG, press the Latch softkey on the Cisco Unified IP Phone. You can disengage the latch by pressing the Stop softkey. (On some phone models, you must press the More softkey to see Latch.)

Step 7 When you are done talking, release the PTT softkey to return to listen-only mode.

Step 8 When you are done using the Cisco IPICS service, press the Logout softkey.

On some phone models, you must press the More softkey to see Logout.
