I am trying to route my calls through an outside IAX provider. I
am having a problem with which codec to use. The only way I have
successfully been able to make an outgoing call is if i do:<br>
<br>
<div style="margin-left: 40px;"> disallow=all<br>
allow=g729<br>
</div>
<br>
in the sip.conf file (for my phones) and the iax.conf file. The second I add one more codec to that list, for instance:<br>
<br>
<div style="margin-left: 40px;"> disallow=all<br>
allow=g729<br>
allow=ulaw<br>
</div>
<br>
I get the following error in the CLI:<br>
<br>
<div style="margin-left: 40px;"> Nov 23 10:56:35 NOTICE[3799]: channel.c:1703 ast_set_write_format: Unable to find a path from ulaw to g729<br>
Nov 23 10:56:35 NOTICE[3799]: channel.c:1736 ast_set_read_format: Unable to find a path from g729 to ulaw<br>
</div>
<br>
During this time, the number I am calling rings, however, when I pick up, the server hangs up and says this:<br>
<br>
<div style="margin-left: 40px;"> -- IAX2/plainvoip/3 is ringing<br>
-- IAX2/plainvoip/3 stopped sounds<br>
-- IAX2/plainvoip/3 answered SIP/4035-0e93<br>

drop call because I couldn't make SIP/4035-0e93 compatible with

</div>
I will post my configuration files if necessary. Thank you in advance for any help that anyone can offer.<br>
