New and Changed Information
Cisco Unified IP Phone firmware release 8.0(2) SR2 supports the latest versions of Cisco Unified CallManager software—version 4.2 and version 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 the "Related Documentation" section for help locating these documents.
DTMF Transport transmits RTP packets in band for each a digit pressed during a call, according to RFC2833. This feature allows an SCCP endpoint to interwork with a SIP endpoint or gateway.
Group Listen Mode
Cisco IP Phone firmware release 8.0(2) SR2 supports Group Listen mode on the Cisco Unified Phone 7911G. In Group Listen mode, both the handset and speaker can be active at the same time. During a call, one user can talk into the handset while other users can listen over the speaker.
Group Listen mode is disabled by default. To enable this mode, you must do so from the Phone Configuration page in Cisco CallManager Administration. If Group Listen mode is enabled, the Monitor feature softkeys are not available on the phone.
Group Listen softkeys are displayed if Group Listen mode is enabled by the administrator on Cisco CallManager. However, these softkeys cannot be configured by using the Cisco CallManager softkey template.
When Group Listen mode is activated, end-users can use Group Listen mode by pressing softkeys:
•GListen—Activates Group Listen on the phone. Users can deactivate Group Listen by hanging up the handset or by pressing GLOff.
•GLOff—Deactivates Group Listen on the phone.
Note If Group Listen mode is enabled, the GListen and GLOff softkeys replace the Monitor and MonOff softkeys on the phone.
Before using the Cisco Unified IP Phone 7911G with Cisco Unified CallManager version 4.2 or version 5.0, you must install the latest firmware on all Cisco Unified CallManager servers in the cluster.
The firmware image name is: SCCP11.8-0-2SR2S.loads
To install the firmware, follow these steps:
Step 1 Go to the following URL:
Step 2 Double-click one of the following hyperlinks, and follow the prompts to download the firmware:
•Cisco Unified CallManager 5.0: cmterm-7911-sccp.8-0-2SR2.cop
•Cisco Unified CallManager 4.2 and earlier:
Step 3 To download the Readme file, which contains installation instructions for the corresponding firmware, go back to the URL shown in Step 1 and click the appropriate hyperlink.
Step 4 Follow the instructions in the Readme file to install the firmware.
Review these important notes for this firmware release.
Cisco Unified CallManager Load Server Setting for Firmware Upgrades
Cisco Unified CallManager Administration contains a setting to optimize installation time for phone firmware upgrades.
The Load Server setting is visible on the Phone Configuration page (Product Specific Configuration section) in the Cisco Unified CallManager Administration application. This setting lets you specify an external TFTP server IP address or name (other than the TFTP Server 1 or TFTP Server 2) from which the phone firmware can be retrieved for upgrades on the phones. When the Load Server is set, the phone contacts the designated server for the firmware upgrade.
Note•If the firmware load is not found on the Load Server, the phone does not upgrade and is not redirected to the TFTP Server 1 or TFTP Server 2.
•On a factory reset or during a software recovery operation, the phone may fall back to using TFTP Server 1 or TFTP Server 2 to recover the phone load. In these scenarios, the phone will recover the phone load either via the term11.default.loads file, or it will attempt to recover the phone load based on its load.hist file.
•If the phone is auto-registering with Cisco Unified CallManager for the first time, the phone will request the phone load via TFTP Server 1 or TFTP Server 2. This will only occur once when the phone is first installed into the system. This can be mitigated by preloading the phones with the correct firmware so that no firmware upgrade is required in combination with the auto-registration, or by auto-registering the phones at the main site prior to deployment at a remote site.
You can view the Load Server setting on the phone from Settings > Device Configuration > Network Configuration > Load Server. If the value in the Load Server setting is invalid, a "Load Server is invalid" message is displayed on the phone in Settings > Status > Status Messages.
Secure PC Logoff in an 802.1X Network
Firmware release 8.0(2) SR2 provides support for the Cisco Unified IP Phone 7911G to monitor IEEE 802.1X messages between an authenticating switch and a connected PC (supplicant).
When a PC is disconnected from the Cisco 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 8.0(2) SR2, be aware that you must re-authenticate a PC that is connected to the Cisco Unified IP Phone 7911G.
For more information about 802.1X re-authentication, refer to the Cisco Catalyst switch configuration guides at:

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.
