7975 Not showing Extension Mobility service

Jonathan Schulenberg · ‎10-27-2008

I'm seeing an odd difference in behavior between 7970 and 7975 phone models surrounding Extension Mobility. This is on a UCM 6.1(2) install.

The environment has been using 7970 as their primary production phone model for some time. Extension Mobility has been configured without issue and working as expected.

The first batch of 7975 phones arrived last week for new users. The same process was followed to enable EM on these phones (enable Extension Mobility and subscribe the service to the device); however, when the Services button is pressed, the service does not appear as an option. There is no error displayed on the device, the list is just blank.

Has anyone run into this or have ideas what has changed in the 7975 XML behavior?

When you use firmware release 8.3(3) with Cisco Unified Communications Manager 6.x, you must use Cisco Unified Communications Manager engineering special release. If this is not used, you will receive an XML parse error when you login or logout of a Cisco Unified IP Phone. Take a look at this bugâ€œCSCsj79645â€.
