[Freeswitch-users] BEARERCAPABILITY_NOTAVAIL with 1.6.6 on Debian 8

[Kim Rostgaard Christensen]

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
