CCM 4.1(2) & 7961G-GE

I am having trouble getting the phone to register with the call manager. Phone display says Registration Failed: Error Mismatch.

There is also an alarm in the CCM Trace log file. Says Device Type Mismatch - UNKNOWN_PARAMTYPE: Device Type:308

UNKNOWN_PARAMTYPE: Database Device Type: 30018

Are those two parameters supposed to match? And is this phone compatible with this version of Call Manager?

Thanks for helping in advance.

Hi Dave,

I don't believe the 7961G-GE is supported on CCM 4.1(2)

Supported CallManager Versions

The Cisco IP Phone 7961G/7961G-GE and 7941G/7941G-GE firmware release 7.0(2) is supported on these Cisco CallManager versions:

•Cisco CallManager version 4.1(3) SR1 or later

•Cisco CallManager version 4.0(2) SR2b or later

•Cisco CallManager version 3.3(5) SR1 or later

Hope this helps!
