This *should* be something that’s easy to fix, but apparently I’m not
doing something right.

Our SIP long distance provider is telling us to only use formats G.723
and G.729, so I’ve set up their trunk configuration in sip.conf as such:

[t564]
type=friend
host=XXX.XX.56.4
context=default
disallow=all
allow=g723
allow=g729

However, the Dial application gives the following error:

    That’s fantastic. I’ll tell that to our SIP trunk provider right away.

    So G.729 will only work for this trunk if the customer’s ATA is using it too?
