We've had a sort-a breakthrough:<br>
<br>
If we override the codec string<br>
originate loopback/5900/default
&bridge({absolute_codec_string='PCMA,PCMU'}sofia/gateway/gw/number)<br>
<br>
We can get the gateway to accept our call. This is most like due
to them not supporting L16 - which makes the
BEARERCAPABILITY_NOTAVAIL make sense. Yay!<br>
<br>
SDP then becomes:<br>
<br>
v=0<br>
o=FreeSWITCH 1464414375 1464414376 IN IP4 192.168.1.4<br>
s=FreeSWITCH<br>
c=IN IP4 192.168.1.4<br>
t=0 0<br>
m=audio 24744 RTP/AVP 8 101<br>
a=rtpmap:8 PCMA/8000<br>
a=rtpmap:101 telephone-event/8000<br>
a=fmtp:101 0-16<br>
a=ptime:20<br>
<br>
And everything is fine. Sound comes through, and connection is
stable.<br>
<br>
This raises two questions:<br>
<br>
1. We would really like the default behaviour to use PCMA/8000 for
outbound bridged channels.<br>
How do we go about this?<br>
<br>
2. Is this intended that a minor release should have such large
impact on the SDP and, if so, can anyone elaborate on this?<br>
<br>
Best<br>
