the legs separately as if they were not related to the same call. So the
ingress leg negotiates ulaw, and despite it knowing that the peer also
supports g729 fails the call since it's already decided on ulaw and the
egress leg only accepts g729.
If this is design intent I'm wondering if there is demand enough to justify
a feature request?
Any advice on how I can work around this issue?...

Codec negotiation issue (no audio format found to offer)
Running build 1.8.5.0 (compiled from source) I seem to be having an issue
with codec negotiation. I have a Grandstream HT503 FXO port connected to a
pstn line, a Polycom SP501, and a SIP trunk with callwithus.

ulaw) to be used to the Grandstream FXO or any other internal endpoint, and
for g729 only to be used outbound to my SIP trunk.
Here are the basics of my config, showing the codec list from "sip show peer
<peer>":

WARNING[25423] chan_sip.c: Asked to transmit frame type slin, while native formats is 0x4 (ulaw) read/write = 0x4 (ulaw)/0x4 (ulaw)
This error repeats 10-11 times quickly (within 1 second) prior to the SIP CANCEL. (see sample of logs below)
3. Other interesting lines from the asterisk full log:
