This is SIP channel you need to limit. Forcing ulaw only, the Polycom will fall
back to ulaw.
Per peer, in your sip.conf:

allow=ulaw

The PSTN only allows ulaw or alaw (depending on your location). You
CANNOT send calls in any other codec over a PSTN line. Generally, if
you want to use G729 then you must buy a G729 license (with a few

That would work just spiffy if you are calling another SIP device, but
by the time the call gets to that point in the dialplan the codec of the
originating device has already been chosen and set in stone.

If you want to get a G729 call to go via Zap you must purchase

I guess that's my frustration, I don't want it g729, I want it ulaw, I
just wish Zap did codec negotiation from the client. It'd be a nice
option instead of automatically trying to translate if it's not ulaw.
Could save some processor overhead(obviously at the expense

Asterisk builds two channels and bridges them together. If the codecs
mis-match then it must transcode, the negotiation

Correct, but if I have two sip peers, one with G729ulaw, the other with
gsmulaw, they will negotiate before trying to send audio.
With ZAP, it tries to transcode whatever it receives into ulaw, period.
No negotiation to even tell the client to send ulaw if capable
In the sip peer definition,
disallow=all
allow=g729
allow=ulaw
SHOULD work. Asterisk can't transcode g729, so it should fall on ulaw
for the ZAP calls. But, when your polycoms talk with each other, as
long as all necessary REINVITEs happen, they should use the 729 codec I
believe. Remember

Is there a way to force Zap channels to only use ulaw, and not even attempt

My polycom 550 has G729,ulaw as priority, the Zap always fails b/c I'm not
licensed for the codec on the asterisk box.
