Our Telepresence solution includes CUCM 7.1, CTMS 1.6, CTM 1.6, CTS-3210 and CTS-1300 Endpoints, Cisco 3945 with MFT-E1 and DSP modules as the PSTN Gateway.
We want to use audio add-in function in the solution.
Do we need additional equipment (like IPVC) for this solution?
Audio Add-in for multipoint conference also needed.
Thanks in advance.
Audio Add-in is Audio only calls, your PSTN GW should be enough. This Audio-add in feature is like a regular voice call
For Interop you need CUVC
