If you define your iax channel in terms of type=user and type=peer, you
can define your codec preference. At least it works for iax links to
other asterisk boxes, so presumably it works with iax clients as well.
I'd have to guess it might work with sip as well, if you fully understand
what parameters are used to find matching contexts, etc.
