New and Changed Information
Cisco Unified IP Phone firmware release 8.0(1) supports the latest releases of Cisco Unified CallManager software—release 4.2 and release 5.0. For a list of new and changed phone features introduced in these Cisco Unified CallManager versions, refer to the Release Notes for Cisco Unified CallManager 4.2 and the Release Notes for Cisco Unified CallManager 5.0. See "Related Documentation" section for help locating these documents.
Cisco Unified IP Phone firmware release 8.0(1) supports DTMF Transport. DTMF Transport transmits RTP packets in band for each a digit pressed during a call, according to RFC2833. This allows an SCCP endpoint to interwork with a SIP endpoint or gateway.
Before using the Cisco Unified IP Phone 7960G and 7940G with Cisco Unified CallManager release 3.3 or later, you must install the latest firmware on all Cisco Unified CallManager servers in the cluster. The firmware image name is P00308000100 for these releases of Cisco Unified CallManager:
•For Cisco Unified CallManager release 4.2 and earlier
•For Cisco Unified CallManager release 5.0 and later
If you are using the Cisco Unified IP Phone Expansion Module 7914, you must upgrade the expansion module to firmware release S00105000100 before you use the phones. You can download the installation program, which is named cmterm-7914-sccp.5-0-1.exe, and the readme file from Cisco.com at this location:
To download and install the firmware, follow these steps:
Step 1 Go to the following URL:
Step 2 Click one of the following hyperlinks, and follow the prompts to download the firmware:
•For Cisco Unified CallManager release 4.2 and earlier: cmterm-7940-7960-sccp.8-0-1.exe

Step 3 Go back to the URL shown in Step 1, click the following hyperlink and follow the prompts to download the Readme file, which contains installation instructions for the corresponding firmware:
For Cisco Unified CallManager release 4.2 and earlier and Cisco Unified CallManager release 5.0 cmterm-7940-7960-sccp-8-0-1.Readme.htm
Step 4 Follow the instructions in the Readme file to install the firmware.
This section includes information about using Cisco Unified IP Phones with Cisco Unified CallManager and includes these topics:
Configurable SRST Router Fallback Waiting Period
When a Cisco Unified IP Phone loses its connection to the Cisco CallManager server, the connection fails over to an SRST router. After a failover to an SRST router, the phone will monitor the links to the Cisco Unified CallManager servers that the phone can register to. When a server has been available for two minutes, by default, the phone will fall back from the router to that server.
You can change this default time by specifying another value for the station connection monitor duration parameter in Cisco Unified CallManager Administration. For more information, refer to Cisco Unified CallManager Administration Guide.
Using Barge on an Encrypted Call
Cisco Unified IP Phone 7960G and 7940G users cannot barge into an encrypted call if the phone that is used to barge is not configured for encryption. When barge fails in this case, a fast busy tone plays on the phone where the user initiated the barge. No error message displays on the initiator phone to indicate that barge failed because the call is encrypted.
If the initiator phone is configured for encryption, the barge initiator can barge into an authenticated or nonsecure call from the encrypted phone. After the barge occurs, Cisco Unified CallManager classifies the call as nonsecure.
If the initiator phone is configured for encryption, the barge initiator can barge into an encrypted call, and the phone indicates that the call is encrypted.
A user can barge into an authenticated call, even if the phone that is used to barge is nonsecure. The authentication icon continues to display on the authenticated devices in the call, even if the initiator phone does not support security.
Secure PC Log Off in an 802.1X Network
The Cisco Unified IP Phone 7960G and 7940G can monitor IEEE 802.1X messages between an authenticating switch and a connected PC (supplicant). When a PC is disconnected from the Cisco Unified IP Phone, the phone issues an EAPOL-Logoff message on behalf of the PC to the authenticating switch. The proxy EAPOL-Logoff message causes the authenticating switch to set the port to an unauthenticated state.
If you have an 802.1X network and upgrade to Cisco Unified IP Phone firmware release 7.2(2) or greater, be aware that you must re-authenticate a PC that is connected to a Cisco Unified IP Phone after the upgrade.
For more information about 802.1X re-authentication, refer to the Cisco Catalyst switch configuration guides at:
