[Asterisk-Users] How to run different codecs between the same endpoints on an IAX trunk?

Well, push comes to shove, you can define two different entries in
iax.conf with different protocols. That is:

Box A:
[boxb-voice]
type=peer
host=boxb
disallow=all
allow=gsm
trunk=yes

[boxb-data]
type=peer
host=boxb
disallow=all
allow=ulaw

You'll lose some of the benefits of trunking for the data calls, but
if they're short-lived and not terribly common, this might be the
easiest solution.
