We've had a sort-a breakthrough: If we override the codec string originate loopback/5900/default &bridge({absolute_codec_string='PCMA,PCMU'}sofia/gateway/gw/number) 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! SDP then becomes: v=0 o=FreeSWITCH 1464414375 1464414376 IN IP4 192.168.1.4 s=FreeSWITCH c=IN IP4 192.168.1.4 t=0 0 m=audio 24744 RTP/AVP 8 101 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20 And everything is fine. Sound comes through, and connection is stable. This raises two questions: 1. We would really like the default behaviour to use PCMA/8000 for outbound bridged channels. How do we go about this? 2. Is this intended that a minor release should have such large impact on the SDP and, if so, can anyone elaborate on this? Best Kim On 2016-05-27 16:32, Kim Rostgaard Christensen wrote:
We finally got around to getting a SIP trace.
The only difference we can find is in the SDP
1.6.2:

Any hints?

Hi Ken,
It doesn't work from our dialplan either:
<extension name="foobar" continue="true"> <condition field="destination_number" expression="^external_transfer_(\d+)$"> <action application="set" data="ringback=${dk-ring}"/> <action application="ring_ready" /> <action application="bridge" data="[fifo_music=default]sofia/gateway/${default_trunk}/$1"/> <action application="hangup"/> </condition> </extension>
That works swimmingly with 1.6.2, but fails with BEARERCAPABILITY_NOTAVAIL with 1.6.6.

I doubt that was ever an intended feature... why not just send the A leg out and park the bleg just reverse your notation there

Hi all,
Using 1.6.2 this works from fs_cli and dialplan:
originate loopback/park/default &bridge(sofia/gateway/server/xxxxxxxx)
Using 1.6.6 it fails with BEARERCAPABILITY_NOTAVAIL.
