I have
the same problem here, why does asterisk not use ulaw with Sip1 -> Sip3
? As it has allow=g729 and allow=ulaw in Sip1, should it not fallback onto
ulaw when the g729 fails?
Thanks,
Dean.

1)pay digium for g.729 license or
2)allow g.729 for sip3
- sip 1 -> sip2 work cause it will pass thru,
- sip 2 -> sip3 fails because since asterisk wants to do transcoding to 729<->711 and no license
if bandwidth is a concern just use GSM (if available as a codec on the phone)

My test-setup is as follows :
sip1 <--> Asterisk <--> sip2
^
|-------> sip3
In sip.conf,
[sip1]
type=friend
host=dynamic
secret=pass
disallow=all
allow=g729
allow=ulaw
[sip2]
type=friend
host=dynamic
secret=pass
disallow=all
allow=g729
[sip3]
type=friend
host=dynamic
secret=pass
disallow=all
allow=ulaw
sip1 supports g.729 and g.711u only
sip2 supports g.729 only
sip3 supports g.711u only
sip1 is able to establish a call to sip2.
However, I have problem establishing a call from sip1 to sip3. sip3
rings but when I answered it, it hanged up.

I think the codecs used by sip3 and sip1 are incompatible. Does anyone
know how I could make them compatible ?
Thank you.
