[Freeswitch-users] static rtpmap entries are not shown in outbound invites

[Leon de Rooij]

Hi Brian,

Thanks, that works :-)

I got one last question about sdp, would you know why chan var ep_codec_string isn't set after an incoming invite with the following sdp:

v=0.
o=FOOBAR 123456 654321 IN IP4 1.2.3.4.
s=-.
c=IN IP4 1.2.3.4.
t=0 0.
m=audio 22262 RTP/AVP 18 101.
a=rtpmap:18 G729/8000/1.
a=rtpmap:101 telephone-event/8000/1.
a=fmtp:101 0-15.

Can it be the trailing /1 (encoding parameters) on both rtpmaps ? - According to parse_rtpmap() in libsofia it should be parsed alright, but still, ep_codec_string gets filled when I receive an SDP like this (from another endpoint):

v=0.
o=BARFOO 20494030 20494030 IN IP4 4.3.2.1.
s=-.
c=IN IP4 4.3.2.1.
t=0 0.
m=audio 50000 RTP/AVP 18 100.
a=rtpmap:18 G729/8000.
a=sendrecv.
a=ptime:20.
a=rtpmap:100 telephone-event/8000.
a=fmtp:100 0-15.


(btw, I'm having inbound- and outbound-codec-prefs on the incoming profile set as: "G7221 at 32000h,G7221 at 16000h,G722,PCMA,PCMU,G729,GSM" and am doing inbound-late-negotiation="true")


Thanks,

Leon
