Cisco Unified IP Phone 7961G, 7961G-GE, 7941G, 7941G-GE Release Notes for Firmware Release 8.2(2)SR2 (SCCP and SIP)

---

April 27, 2007

Use these release notes with a Cisco Unified IP Phone 7961G, 7961G-GE, 7941G, and 7941G-GE running SCCP or SIP firmware release 8.2(2)SR2.

The SCCP version of firmware release 8.2(2)SR2 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(2)SR2 is compatible with Cisco Unified CallManager release 5.1 and 5.0.

---

Note SIP firmware release 8.2(2)SR2 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.

Note The Cisco Unified CallManager New and Changed Information Guide, Release 5.1(1) describes new and changed 5.1(1) software features and acts as a supplement to the Cisco Unified CallManager Release 5.0(4) document set. Content in the New and Changed guide supersedes information contained in the 5.0(4) document set; however, chapters in the New and Changed guide may contain references to 5.0(4) documents. In such cases, refer to the 5.0(4) documents for more information.

New and Changed Information

This section contains new and changed information about features introduced in firmware release 8.2(2)SR2.

---

Note This information is not documented in the latest release of the Cisco Unified IP Phone Administration Guide for Cisco Unified CallManager 5.1, Cisco Unified IP Phones 7961G/7961G-GE and 7941G/7941G-GE.

---

Cisco Discovery Protocol (CDP) Enable/Disable

Firmware release 8.2(2)SR2 supports enabling or disabling the Cisco Discovery Protocol (CDP), which performs device discovery and sends configuration information from the switch to the phone.

---

Note CDP should be enabled on the switch port when the phone is connected to a Cisco switch. CDP is important for phone VLAN assignment, power negotiation, QoS management, and 802.1x security.

---

The CDP enable/disable feature supports response to Denial of Service (DOS) activity that affects Cisco phones when the phones are connected to non-Cisco switches. A non-Cisco switch might not filter the CDP messages, and, if CDP is enabled on the PC or switch port, messages might be multicast to all the phones on the switch. However, when CDP is disabled, the phone does not generate CDP messages and ignores any received CDP messages.

If CDP is disabled on the switch port, the phone cannot obtain VLAN information from an upstream switch port; however, the VLANs can be set manually by configuring the Admin VLAN on the phone.

To configure CDP enable/disable, use these fields on the Phone configuration page in Cisco Unified Communications Manager:

•Cisco Discovery Protocol (CDP): PC Port—Indicates whether CDP is enabled on the PC port (default is enabled). CDP must be enabled on the PC port when Cisco VT Advantage/Unified Video Advantage (CVTA) is connected to the PC port. CVTA does not work without CDP interaction with the phone.

•Cisco Discovery Protocol (CDP): Switch Port—Indicates whether CDP is enabled on the switch port (default is enabled).

---

Note The current CDP values are visible on the Settings menu.

---

Version Stamp Mismatch Recovery (SIP Only)

If a Cisco Unified IP Phone (SIP) configuration is not synchronized with the Cisco Unified CallManager configuration, the IP Phone may restart several times before it successfully registers.

Firmware release 8.2(2)SR2 provides the following methods to detect a configuration mismatch:

•Reason_code 14 is added to the DeviceUnregistered alarm to indicate a version mismatch.

•New RTMT perfmon counters in the Cisco SIP Station category indicate how many version mismatches were detected:

–ConfigMismatchesTemporary—Number of devices that experienced a configuration mismatch that was automatically recovered

–ConfigMismatchesPersistent—Number of devices that experienced a configuration mismatch that was not automatically recovered

If a DeviceUnregistered alarm displays a reason_code of 14 (configuration mismatch) and the device is not automatically recovering, you must re-save the device configuration in Cisco Unified CallManager Administration.

This section describes how to install firmware release 8.2(2)SR2 for SCCP.

Firmware Upgrade Issues for SCCP

Note the following firmware upgrade issues:

•If you are currently running firmware earlier than 6.0(2) on a Cisco Unified IP Phone 7961G, 7961G-GE, 7941G, or 7941G-GE and want to upgrade to 8.0(x), you must first install an intervening 7.0(x) load to prevent upgrade failure. Cisco recommends using the most recent 7.0(3) load as the intervening load to avoid lengthy upgrade times.

•If you are currently running firmware 6.0(2) to 7.0(2) on a Cisco Unified IP Phone 7961G, 7961G-GE, 7941G, or 7941G-GE and want to upgrade to 8.0(x), you can do so directly. However, expect the upgrade to take twice as long as usual.

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(2)SR2 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:
