New and Changed Information

Cisco Unified IP Phone firmware release 8.0(1) supports the latest versions of Cisco Unified CallManager software—versions 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 the "Related Documentation" section for help locating these documents.

DTMF Transport

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.

Installation Notes

Before using the Cisco Unified IP Phone 7911G with Cisco Unified CallManager release 4.2 or release 5.0, you must install the latest firmware on all Cisco Unified CallManager servers in the cluster.

The 8.0(1) firmware release has been made available on Cisco Unified CallManager installation CDs; however, it will not be made available on due to additional bugs filed during final testing. Cisco recommends that you instead use the updated 8.0(2) SR2 firmware load, which is now available on This recommendation is limited to this specific firmware release and has no bearing on any other software or firmware available on Cisco Unified CallManager CDs.

The SCCP 8.0(2) SR2 installation programs for the 79711G are named as follows:

for Cisco Unified CallManager 5.0: cmterm-7911-sccp.8-0-2SR2.cop

for Cisco Unified CallManager 4.2 and earlier:


The readme file that contains installation instructions is named:


All of these 8.0(2) SR2 files can be downloaded from this location on

Note Cisco recommends installing 8.0(2) SR2 instead of 8.0(1), as explained earlier in this section.

Important Notes

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.

Note The setting is intended for future use and is not yet a supported feature.

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 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.

NoteIf the firmware load is not found on the Load Server, the phone does not upgrade and is not redirected to 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(1) 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(1), 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:

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:

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)

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)—Your 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 operation 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 your network is impaired, but 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.
