Do a SIP packet capture and see what the SDP in the INVITE is telling each end
to expect from the other.

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.
