Hello,
I am trying to set up a Webrtc by using Kamailio, Asterisk and Rtpengine. So
far, everything is working fine , I'm able to register an extension and make a
call, but for some reason, when i'm trying to call a WebRTC extension from any
SIP Extension from Asterisk, Kamailio is sending INVITE, WebRTC extension is
sending back 200 OK, and then Kamailio is trying to send an ACK through UDP
protocol, and not through wss, as it's supposed to do.
In console, I see:
Sep 21 20:39:06 vsphone3-sbc /usr/sbin/kamailio[9756]: WARNING: {1 102 ACK
[email protected]:5060} <core> [core/forward.c:231]:
get_send_socket2(): protocol/port mismatch (forced tls:172.16.11.57:8443, to
udp:187.20.56.83:27730)
My scenario is:
Internet -> Firewall -> Kamailio -> Asterisk
Working:
Softphone -> Kamailio -> Asterisk (TCP/UDP/TLS(SRTP)
Asterisk -> Kamailio -> Softphone (TCP/UDP/TLS(SRTP))
Webrtc -> Kamailio -> Asterisk (WSS)
Not Working:
Asterisk -> Kamailio -> Webrtc
After a answer from Webrtc, I can listen sound, so, RTP in theory is fine.
Webrtc send 200 OK to Kamailio
Kamailio Send 200 OK to Asterisk.
Asterisk Send ACK to Kamailio
ACK not forwarded to Webrtc.
In attachment, my kamailio.cfg
Every Help is welcome.
Thanks
Neimar.
