7961G IP Phones not registering CM4.1

[carlton.reid]

The phones in question are not registering with CM4.1. I think its because of the lack of backward compatibilty with the CM4.1 firmware for the 7961G and the default firmware for the 7961G but I am not sure.

The phones have got the term61.default firmware and the CM4.1 is set to P00308000400 firmware.

Can anyone confirm the SCCP Firmware filename version that the 7961G phone supports, is it version 7 or 8.

Has anyone experienced similiar issues, your input would be very much appreciated.

best regards

Hi Carlton,

For Java-based IP phones, the following naming conventions are used for image files:

SCCP firmware-TERMnn.xx-y-z-ww or SCCPnn.xx-y-zz-ww, where n represents the phone type, x represents the major version, y represents the major subversion, z represents the maintenance version, and w represents the maintenance subversion.

The following example shows how to configure Cisco Unified CME so that the Cisco Unified IP Phone 7941 can download the appropriate SCCP firmware from flash memory:

Router(config)# telephony-service

Router(config-telephony)#load 7941 SCCP41.7-2-1-0S

For Java-based IP phones, such as the Cisco Unified IP Phone 7911, 7941, 7941GE, 7961, 796GE, 7970, and 7971, the firmware consists of multiple files including JAR and tone files. All of the firmware files for each phone type must be downloaded the TFTP server before they can be downloaded to the phone.

The following example shows a list of phone firmware files that are installed in flash memory for the Cisco Unified IP Phone 7911:

tftp server-flash:SCCP11.7-2-1-0S.loads

tftp server-flash:term06.default.loads

tftp server-flash:term11.default.loads

tftp server-flash:cvm11.7-2-0-66.sbn

tftp server-flash:jar11.7-2-0-66.sbn

tftp server-flash:dsp11.1-0-0-73.sbn

tftp server-flash:apps11.1-0-0-72.sbn

tftp server-flash:cnu11.3-0-0-81.sbn

However, you only specify the filename for the image file when configuring Cisco Unified CME

Hope this helps!
