We just got our 7921 wireless phones and the release notes and guides says we can use a Push to Talk XML application on them. I can't see to find the instructions to setup Push to Talk on the 7921s. Does anyone know if it's a built-in service like Extension Mobility or do we need to purchase this from a 3rd party? Thanks in advance.

Hi Stu,


This is not a built-in service (at least yet). Have a look at the following;


Q. Is Push-to-talk (PTT) natively supported on Cisco Unified CallManager or does it require a third-party application and server?


A. PTT is not supported natively on Cisco Unified CallManager. To support PTT, the Cisco Unified Wireless IP Phone 7921G relies on support via an XML application.


Q. How is PTT different on the Cisco Unified Wireless IP Phone 7921G compared to the Cisco Unified Wireless IP Phone 7920?


A. The Cisco Unified Wireless IP Phone 7921G has a dedicated application button that supports PTT via XML; the Cisco Unified Wireless IP Phone 7920 uses soft keys for PTT.


Q. Does the Cisco Unified Wireless IP Phone 7921G support XML?


A. Yes. In fact, several third-party vendors are building XML applications that work with the Cisco Unified Wireless IP Phone 7921G.

Check out Berbee (Push to Talk)
