We are trying to use one Polycom HDX 7000 as H323 phone client with a CCM 5.0.4.
We did the same configuration with our old Aethra Videoconference appliances and they work fine.
With Polycom we have these problems:
a) one way audio when I call from my 7985 (no audio on Polycom)
b) no audio and video when I call from one 7940 with VTA (no audio/video on 7940 side, no audio on Polycom)
c) I cannot add the Polycom to a multiconference (we have a 3515 mcu).
