Do a SIP packet capture and see what the SDP in the INVITE is telling each end to expect from the other. > I'm receiving incoming calls via the provider, asterisk correctly > dials the phone where the calls are suposed to go to, the phone > rings --- and when I pick it up, there is no audio in either direction. Sounds like the setup is trying to do direct media - which obviously cannot work between an IPv4-only phone and an IPv6-only provider. Make sure Asterisk remains in the audio path and it should "almost transcode" for you. I have audio working over just such an arrangement (in my case, an IPv4-only provider, and phones connected via IPv6) without problems.
