That's it! That's it! That's it! Thank you, thank you thank you.
Your answer came in at the same time I was trying that.
Yes, when I look at Call Status it shows callcentric coming in with G729 and GV going out with 711U.
I took CC's "guess" and turned off all codecs except G711U and it worked!!!
So my only follow up issue is : can I live with only G711U and no G729??
OR
Is there some place in settings where I can say if/when I call out on the CC line can I say use G729
and seems GV only likes G711U???
thanks again!
cheers
