[Asterisk-Users] g729 passthrough?

[Brian Capouch]

I'm sitting here with my dunce cap on.  My weak excuse is that I haven't 
ever played with g729 before.

I have a Sipura 841.  I have the phone config set to use g729.   Its 
appropriate sip.conf entry, and the IAX stanza for my ITSP all set to 
disallow=all, allow=g729.

But as soon as I dial, I get a complaint from the server:

     -- Call accepted by 66.225.202.72 (format g729)
     -- Format for call is g729

Apr 24 15:38:38 NOTICE[5586]: channel.c:1833 set_format: Unable to find 
a path from g729 to slin

. . . .

I get ringback from Nufone, but as soon as the call answers I get an error:

Apr 24 15:43:42 NOTICE[5596]: channel.c:1833 set_format: Unable to find 
a path from g729 to slin

. . .

What am I doing wrong to cause it to want to transcode?  I assume that's 
where the complaint is coming from.  I thought Asterisk could pass 
through without transcoding as long as the endpoints are all g729.

Thanks.
