Yoav, I've subscribed you to the list...
What i meant to say about G722 that even if you see G722/8000 in the config window and inthe INVITE packet the actual audio stream is sampled at 16 Khz About dtmf payload: You say that you click on dialpad buttons and you don't see packets with the DTMF payload in the rtp stream? Strange it works perfectly well here. Can you send me a wirshark capture of this scenario?
