[asterisk-users] Asterisk removes ice lines in sdp when calling between webrtc clients

[Olli Heiskanen]

Hello,

I have a problem with a call between 2 webrtc clients. Asterisk removes the
ice-related lines from the sdp when it sends the INVITE out, and the called
webrtc client rejects the INVITE due to the missing ice lines. Both webrtc
clients are defined exactly the same way, same values in all fields except
the number of the peer.

There's probably something I've changed that causes this behavior. Can
anyone tell me what's wrong in my configuration?

res_rtp_asterisk is included in the compilation and uuid-devel is
installed, Asterisk version is 11.11.0. Ice is enabled in rtp.conf as well
as in both clients in the realtime sip peer table.

Here's my realtime peer data:
*CLI> realtime load sippeers name 660

                        domain  testers.com
                    sippasswd2

and my sip.conf:

[general]
bindport = 5070
bindaddr = PU.BL.IC.IP
udpbindaddr = PU.BL.IC.IP
tcpenable = yes
limitonpeers = yes
rtcachefriends = no
tos_sip=cs3
tos_audio=ef
realm = testers.com
autodomain=yes
domain=PU.BL.IC.IP
domain=testers.com
transport=ws,wss,udp
outboundproxy=PU.BL.IC.IP:5060


I'd appreciate Your advice.

cheers,
Olli
