Hi

Is there a reason why freeswitch sends a double DSP payload in the SIP
invite from a gateway? The problem is that the payload is too big that It
gets fragmented and then it fails because of that.

v=0
o=FreeSWITCH 1509455513 1509455514 IN IP4 208.90.97.6
s=FreeSWITCH
c=IN IP4 208.90.97.6
t=0 0
m=audio 16724 RTP/AVP 0 101 13
a=rtpmap:0 PCMU/8000
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-16
a=rtpmap:13 CN/8000
a=rtcp-mux
a=rtcp:16724 IN IP4 208.90.97.6
a=ptime:30
m=audio 16724 RTP/AVP 18 0 8 3 101 13
a=rtpmap:18 G729/8000
a=fmtp:18 annexb=no
a=rtpmap:0 PCMU/8000
a=rtpmap:8 PCMA/8000
a=rtpmap:3 GSM/8000
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-16
a=rtpmap:13 CN/8000
a=rtcp-mux
a=rtcp:16724 IN IP4 2

Any comments?
