[Freeswitch-users] Enable Video for external calls

Tue Sep 13 17:10:55 MSD 2016

I’m confused because that pastebin shows the freeswitch properly setting up the call with OPUS for audio and VP8 for video.  Yet your initial problem description said there was no video on the B leg.

Sip trace:

For your understanding - im using kamailio as registrar there. FS as media and Services server
so call goes:

WebRTC client A -> (websockets) -> Kamailio -> (udp) -> FreeSwitch
|__________________Leg A__________________________________|

FreeSwitch -> (udp) -> Kamailio -> (websockets) -> WebRTC client B
|__________________Leg B__________________________________|

I will make sip trace little bit later (in 2-3 hours from now).
And yes.
For now it is a simple proxy call from one A to B without any changes. 
And the SDP all ok. B leg has 
a=video 
and its staff

At the next step i need to generate B leg by myself from freeswitch after some handling leg A. So i suppose that settings for now not enought for this scenario. am i right?

I'm expecting to see b side without video capabilities.
So do the sofia global sip trace on and see the invite leaving fs box. Check if sdp has both audio and video m flags, and what was in 200ok sdp back from b side.

Thanks, and a SIP trace showing the call, and the failed negotiation for video?

To be clear, is this a simple bridging scenario (you have an inbound call offering video and you want to bridge it to an outbound B leg which also offers video)?

But i suppose this helped.
Also codecs mached

Am i will be right if i say that 1.6 supports VP8?
I just asking because not found any mod_vpx or something like thais at the mod dir.

There are a bunch of params that can impact SDP negotiation.  I think it would be most helpful if you could pastebin the sip profile settings and then an actual trace of a call

Yep. that in it. 

freeswitch/vars.xml
<X-PRE-PROCESS cmd="set" data="global_codec_prefs=OPUS,G722,PCMU,PCMA,VP8"/>
<X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=OPUS,G722,PCMU,PCMA,VP8"/>

freeswitch/sip_profiles/external.xml

<param name="inbound-codec-prefs" value="$${global_codec_prefs}"/>
<param name="outbound-codec-prefs" value="$${outbound_codec_prefs}"/>

I making call as

session:execute("bridge","sofia/external/"..session:getVariable("destination_number").."@my.sip.pro.xy")

2016-09-12 16:24 GMT+03:00 Mirko Brankovic <mirkobrankovic at gmail.com <mailto:mirkobrankovic at gmail.com>>:
make sure you have video codecs enabled in vars.conf for outbound codec list
