[asterisk-users] no audio both ways with ipv6

when asterisk registers with the VOIP provider via ipv6 and when
local phones don't work with ipv6 but only with ipv4, am I to
expect issues?

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.

There are no packets showing up in the logs as being rejected by the
firewall.  I can make outgoing calls just fine, and those are with
the VOIP provider on one side and the same ipv4 phone on the other.

How can it be that incoming calls have no audio?
