[Freeswitch-users] Speex VBR and VAD

[Dan Lane]

Hi,

Is there any way to tell Freeswitch to enable VBR and VAD on Speex
channels as it appears to be disabled by default and I can't find any
mention of it in the wiki or previous mailing list posts.

The client is sending the following SDP:

a=rtpmap:111 speex/16000/1
a=fmtp:111 vbr=on
a=rtpmap:110 speex/8000/1
a=fmtp:110 vbr=on
a=rtpmap:0 GSM/22050/1
a=rtpmap:0 GSM/11025/1
a=rtpmap:3 GSM/8000/1
a=rtpmap:0 PCMU/8000/1
a=rtpmap:8 PCMA/8000/1
a=rtpmap:113 iLBC/8000/1
a=fmtp:113 mode=30
a=rtpmap:101 telephone-event/8000/1
a=fmtp:101 0-11
a=sendrecv


And receiving back the following without vbr=on which disables it in the client:

a=rtpmap:111 speex/16000
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-16
a=silenceSupp:off - - - -
a=ptime:20



Cheers,
Dan
