Cisco Unified IP Phone 7961G, 7961G-GE, 7941G, 7941G-GE Release Notes for Firmware Release 8.2(1) (SCCP and SIP)
December 8, 2006Use these release notes with a Cisco Unified IP Phone 7961G, 7961G-GE, 7941G, and 7941G-GE running SCCP or SIP firmware release 8.2(1).
The SCCP version of firmware release 8.2(1) is compatible with Cisco Unified CallManager releases 5.1,5.0,4.2,4.1,4.0, and 3.3.
The SIP version of firmware release 8.2(1) is compatible with Cisco Unified CallManager release 5.1 and 5.0.
Note
SIP firmware release 8.2(1) is designed and tested to interoperate with Cisco call control, most notably Cisco Unified CallManager release 5.1. Although SIP firmware is IETF RFC 3261 compliant, it is not supported by Cisco TAC or Engineering for use with non-Cisco call control systems.

Firmware Upgrade Issues for SCCP
Note the following firmware upgrade issues:
•
•
Cisco Unified IP Phone Expansion Module 7914
If you are using the Cisco Unified IP Phone Expansion Module 7914, you must upgrade the expansion module to firmware release S00105000200 before using the phone to support relevant 8.2(1) features on your expansion module.
You can download the installation program, which is named cmterm-7914-sccp.5-0-2.exe, and the readme file from Cisco.com at this location:
http://www.cisco.com/pcgi-bin/tablebuild.pl/ip-7900ser
Firmware Installation Procedure for SCCP
Before using the Cisco Unified IP Phone 7961G, 7961G-GE, 7941G, or 7941G-GE with Cisco Unified CallManager release 3.3 or later, you must install the latest firmware on all Cisco Unified CallManager servers in the cluster.
Before You Begin
If you are upgrading from an earlier firmware version, see the "Firmware Upgrade Issues for SCCP" section.
To download and install the firmware, follow these step

Firmware Upgrade Issues for SIP
If you are currently running firmware 6.0(2) to 7.0(2) on a Cisco Unified IP Phone 7961G, 7961G-GE, 7941G, and 7941G-GE and want to upgrade to 8.0(x), be aware that upgrading will take up to twice as long to complete as usual.
Firmware Installation Procedure for SIP
Before using the Cisco Unified IP Phone 7961G, 7961G-GE, 7941G, and 7941G-GE with Cisco Unified CallManager 5.0 or later, you must install the latest firmware on all Cisco Unified CallManager servers in the cluster.

Failover Time Using TCP is Faster than Failover Time with UDP (SIP Only)
You can configure SIP profiles for the Cisco Unified IP Phone 7961G, 7961G-GE, 7941G, and 7941G-GE to operate with Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) by using the SIP Phone Security Profile Configuration window in Cisco Unified CallManager Administration.
If you select TCP as a transport protocol, the failover time between primary, secondary, and tertiary Cisco Unified CallManagers is approximately five seconds or less. If you select UDP, the failover time is approximately 120 seconds. The TCP phone recovers faster since it detects the TCP link failure faster (less than 5 seconds) where the UDP phone depends on SIP KeepAlive entirely; this can take up to 120 seconds. This scenario applies to a Cisco Unified CallManager `clean' shutdown.
In the case of a Cisco Unified CallManager crash or a router crash, the failover time for a TCP phone and a UDP phone are about the same. In this case, both the TCP and UDP phones rely on SIP KeepAlive to detect the link failure.
Wideband Speech Codecs and MOS Scores
Cisco Voice Transmission Quality (CVTQ) index does not support wideband (7 kHz) speech codecs, as ITU has not defined the extension of the technique to wideband. Therefore, MOS scores that correspond to G.711 performance are reported for G.722 calls to allow basic quality monitoring.
Reporting G.711-scale MOS scores for wideband calls through the use of CVTQ allows basic quality classifications to be indicated as good/normal or bad/abnormal. Calls with high scores (approximately 4.5) indicate high quality/low packet loss, and lower scores (approximately 3.5) indicate low quality/high packet loss.
Unlike MOS, the Conceal Ratio and Concealed Seconds metrics remain valid and useful for both wideband and narrowband calls.
For more information, refer to the "Troubleshooting and Maintenance" section of your Cisco Unified IP Phone administration guide.
How a Cisco Unified IP Phone Determines the TFTP Server Address
A Cisco Unified IP Phone (firmware release 8.0(4) and later) follows an order of precedence for selecting the TFTP server address if the phone receives conflicting information from the DHCP server. For complete information on how the phone selects its TFTP server address, see the "Cisco TFTP" chapter of the Cisco Unified CallManager New and Changed Information Guide, Release 5.1(1).

Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411
Australia: 1 800 805 227
EMEA: +32 2 704 55 55
USA: 1 800 553 2447For a complete list of Cisco TAC contacts, go to this URL:
http://www.cisco.com/techsupport/contacts
Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—An existing network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of the network is impaired while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
