[Freeswitch-users] Number of codecs offerred in SDP

[Mark Campbell-Smith]

Test Setup:

vars.xml:
  <X-PRE-PROCESS cmd="set" data="global_codec_prefs=G729,PCMU,GSM"/>
  <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=G729,PCMU,GSM"/>

The call setup is extension 1000 calls extension 1020
1. Extension 1000 calls with preferred codec PCMU.  PCMU is chosen by
FS as the A-leg codec
2. Extension 1020 only supports GSM codec.  The call fails with Not
Acceptable Here.

FS only offers G729 and PCMU to 1020.  How do I change the number of
codecs that are offered to an extension?  I know I can change the
order in the codec_prefs, but would prefer FS to offer all three
codecs to an extension.

   m=audio 23662 RTP/AVP 0 18 101 13
   a=rtpmap:0 PCMU/8000
   a=rtpmap:18 G729/8000
   a=rtpmap:101 telephone-event/8000
   a=fmtp:101 0-16
   a=rtpmap:13 CN/8000
   a=ptime:30

Thanks
