Solved: Cisco Unified Communications Manager required

Pit Fritz · ‎06-12-2010

Is it absolutely necessary to install the Cisco Unified Communications Manager to use/setup the Cisco Unified Wireless IP Phone 7921G ?

Or can I just connect the phone to the Internet and get incoming SIP calls directly from the VoIP provider?

Hi

The 7921 only supports SCCP which is Cisco's proprietary signalling protocol. Same applies for all the Cisco 792x wireless models as far as I'm aware.

So no, you can't connect it to a SIP provider. There are probably other manufacturers out there doing SIP wireless handsets that would be more appropriate, and likely cheaper.

Hi

That would be a question for the supplier that you purchased it from...

Otherwise there is a healthy market for anything with a Cisco badge on ebay, and lots of specialists dealing in used kit all over the world.

Thanks for your prompt and helpful answer.

Unfortunately I just bought a 7921G which is now of no use for me.

Is there a possibility to give it back?
