CCM 4.2 issue with 7921G

Unanswered Question
Jun 18th, 2009

Hi All,

I have this Problem with a CCM 4.2 I am working on.

It looks like it has all the files to support the software/firmware for the New Phones including Cisco 7921G.

However when I try to add the Cisco 7921G Ip phones in to the system it doesn't show the 7921G as an option to add it.

Any idea why it could be doing that?

Also please see screenshots attached. Thanks Heaps


I have this problem too.

Support for a device is not simply obtained because you have the FW on the server.

Install the latest DevPack available for your version and you should get it as an option. DevPacks update the DB where the supported devices are stored.

Hi java,

Thanks for that. I did that But No change. I installed the latest version and still can't see it on the Phone type available for addition.

What is the exact CCM version???

If you can't see it, you might need to upgrade to the latest SR available to get support for that phone model

Hi Mohammed,

My friend Java is most correct here (+5 points for this Friday Java) This Device Pack with support for the 7921G is not compatible with CCM 4.2(1) you will need to upgrade to CCM 4.2(3) at least.

Cisco Unified CallManager Device Package 4.2.3 (60.0)

Release Notes

Compatibility Matrix and Supported Upgrades

This Cisco Unified CallManager Device Package release is compatible with the following Cisco Unified CallManager versions.


Hope this helps!
