ok now im testing Polycom650 with G722.


I can make a call phone to phone becasue the system does media passthrough.


and i can call G711 to G722 (visa versa). I can hear system prompts..


However if i try to call Exhchange 2007. I get no audio..


personally i think G722 is kick ass sounding.

looks like it might be a trunk issue. I get 1 way audio as well on an outgoing call (to a ulaw provider)

in the SIP message, i see that it use the common codec ulaw. But 1 way audio.


However an incoming call (direct or via exchange) I get 2 way audio.


so outgoing via G722 isnt working. (even though it uses G711)
