Calling Party Normalization

In accordance with E.164 standards, calling party normalization enhances the dialing capabilities of some phones and improves call back functionality when a call is routed to multiple geographical locations. The feature ensures that the called party can return a call without having to modify the directory number in the call log directories on the phone. Calling party normalization allows phone numbers to be presented on the phone based on where the call is going to (intra-city, inter-city, international).

The SCCP and SIP phones support the following functions:

For the final presentation of the calling number to the user, the phone screen displays the calling number based on the international, national, or local subscriber numbers.
For example, if the call is an intra-city call, the phone displays the number in the subscriber format (without the area or city code). For inter-city calls, the phone displays the number in a national number format. For international calls, the phone displays the number in the E.164 format, with the "+" prefix digit.

The call logs directories record the calling number in the received and missed call logs with the appropriate escape codes (for example, 9/0, 0/1, +). The user can go into directories, and select and dial one of these entries with the escape code without having to edit the number.

For information on how to configure this feature for your phone, see "Calling Party Normalization" in the Cisco Unified Communications Manager Features and Services Guide.

Depending on your configuration for global and local calling party number, the phone user may see a localized number, a globalized number with access codes and prefixes, or the international escape character, +, in the calling party number.

If a phone supports calling party normalization, the phone can show the localized calling party number on the phone screen and the globalized number in the call log directories on the phone. In addition, these phones show both the global and local calling party number in the Call Details.

If a phone does not support calling party normalization, the phone shows the localized calling party on the phone screen and in the call log directories on the phone.

In the Call History Details, the E.164 number displays in the Alternate number field.

The Calling Party Normalization feature is supported on the following Cisco Unified IP Phones (SCCP and SIP):

Cisco Unified IP Phone 6921

Cisco Unified IP Phone 6941

Cisco Unified IP Phone 6961

Cisco Unified Communications Manager Features and Services Guide

Client Matter Codes and Forced Authorization Codes

The Forced Authentication Code (FAC) and Client Matter Code (CMC) Support feature extends the FAC and CMC features to more Cisco Unified IP Phones.

FAC controls the types of calls that certain users can place. When placing a call, a user receives a prompt to enter a valid authorization code before the call is made.

CMC enables a user to specify that a call relates to a specific client matter. When placing a call, a user can enter a code to indicate the type of call being placed (for example, to a specific customer).

This release extends the feature from SCCP phones to SIP phones.

The Client Matter Code (CMC) and Forced Authentication Code (FAC) Support feature is supported on the following Cisco Unified IP Phones (SCCP and SIP):

Cisco Unified IP Phone 6921

Cisco Unified IP Phone 6941

Cisco Unified IP Phone 6961

Cisco Unified Communications Manager Features and Services Guide

Disable Single Button Barge

The Disable Single Button Barge feature provides the ability to conference using cBarge. The "Line Key Barge" in the Cisco Unified Communications Manager administration window has the following options:

Default: Pressing the line button causes the user to barge into the selected call.

Off: The result of pressing line button depends on the multiple number of calls per line feature.

When only one call is supported on the line, nothing happens.

When more than one call is supported on the line, a new call starts.

Turn on softkey: When the line button is pressed, the phone displays the softkeys as defined in the remote-in-use template. The phone displays cBarge if configured in the template.


Note The phones do not support the Barge softkey.


The Disable Single Button Barge feature is supported on the following Cisco Unified IP Phones (SCCP and SIP):

Cisco Unified IP Phone 6921

Cisco Unified IP Phone 6941

Phone Display Message for Extension Mobility Users

The Phone Display Message for Extension Mobility Users feature enhances the phone interface for the Extension Mobility user by providing friendly messages. This feature applies to Extension Mobility and Extension Mobility Cross Clusters users.

When the Extension Mobility user logs into the phone, the phone retrieves configuration information from the Cisco Unified Communications Manager, and resets to use the profile of the user. During the reset, the user sees the message "Resetting please wait..." and then "Registering", before the main screen displays.

The Phone Display Message for Extension Mobility Users feature is supported on the following Cisco Unified IP Phones (SCCP and SIP):

Cisco Unified IP Phone 6921

Cisco Unified IP Phone 6941

SRST Notification

The Survivable Remote Site Telephony (SRST) feature maintains a basic level of telephony functionality when the phone cannot communicate with the Cisco Unified Communications Manager cluster. The SRST Notification feature informs the user when the phone cannot communicate with the Cisco Unified Communications Manager.

When communication is lost, the phone displays the message "Service interruption". The message informs the user that the phone is in CM Fallback Service. When communications with the Cisco Unified Communications Manager are restored, the message does not appear.

While communication is lost, some phone features cannot be used because they rely on the Cisco Unified Communications Manager. The following table lists that features that are supported when communication is lost.

Installing Firmware Release 9.2(2) for Cisco Unified IP Phone 6921, 6941, and 6961 (SCCP)

Installation Upgrade Notes

Direct upgrades, using signed load files, are supported to firmware releases 9.2(2) from 9.x. You can use the following firmware release file for these direct upgrades. For Cisco Unified IP Phone 6921, 6941, and 6961 (SCCP and SIP):

cmterm-69xx-sccp.9-2-2-6.cop.sgn

cmterm-69xx-sip.9-2-2-7.cop.sgn


Note Converting SIP to previous 9.1(2) SCCP does not work due to a known issue CSCtj89983. The workaround is to perform factory reset after upgrade completes.



Note Converting previous 9.1(2) SCCP to SIP does not support Auto-Registration due to a known issue CSCth26499.



Note A direct upgrade from firmware release 9.0(x) to 9.2(2) is supported. After you upgrade from an earlier firmware release to 9.2(2) and for subsequent firmware releases, you can upgrade or downgrade only to signed firmware releases.


Before You Begin

If you are using unsigned load and want to upgrade Cisco Unified Communication Manager to release 8.6 and later then manually install unsigned load to upgrade because phone load upgrade will fail due to signed load in Cisco Unified Communication Manager by default.

Errata

The Cisco Unified IP Phone 6921, 6941, and 6961 Administration Guide for Cisco Unified Communications Manager 8.6 has an error in the section "Configuring the Phone to Support Call Waiting" (Chapter 5, page 5-26). The following section replaces the erroneous section.

Configuring the Phone to Support Call Waiting

The Cisco Unified IP Phones 6921, 6941, and 6961 support multiple calls per line. With multiple calls per line, setting up call waiting is simplified on the Cisco Unified Communications Manager. For more information, see the "Understanding Directory Numbers" chapter in the Cisco Unified Communications Manager System Guide.
