I found out that when a subscriber has multiple contacts (ie. by stopping
and starting the WS client), kamailio either fails matching the connection
or matches the wrong one. Setting registrar max_contacts to 1 and using
save("location", "0x04") solved this problem for me.

I am getting this error when trying to call from an ip
phone -> kamailio
-> freeswitch -> kamailio -> jssip. It looks like it can't match the
invited subscriber to a WS connection. Calls from jssip to ip phone works
(although it hangs up after 3-4 seconds for some reason).

Can you get the ngrep on the server from the
initial invite to the ack.
It seems that record route is not properly mirrored, so one client might
mess the route path.
Cheers,

Are you sure the error messages are printed for
this ACK, because it
has to be sent via UDP, not via WS, thus the messages seem to be unrelated.
Get the log messages with debug=3 in order to see what is happening.
Cheers,
Daniel

Hi,
Is it possible that this could be a problem in the script. But when I
call using a normal SIP Client like X-Lite, it works well. This only
happens when the request comes on websocket. Is there something to be
handled specially when handling requests like ACK over websocket?
The reference is more or less taken from

Hi Daniel,
I checked using the kamcmd command and I see the webrtc connection
active. The ACK comes from the webrtc client but somehow kamailio is unable
to create a via header and forward the request. The ACK coming from webrtc
client is as follows:
SEND: ACK sip:1223@126.128.68.8:5065;transport=udp SIP/2.0
Via: SIP/2.0/WS

User-Agent: IM-client/OMA1.0 sipML5-v1.2013.03.27
Organization: Doubango Telecom
Where 126.128.68.9:5060 is the Kamailio; 126.128.68.8:5065 is a
freeswitch playing music and the request is received on
126.128.68.9:8080 which is kamailio acting as a websocket server.
Also the connection between Kamailio and Freeswitch is UDP. I am not
able to use the websocket module just because of this small problem caused
in signaling. Any help is really appreciated. Could it be related to the
nathelper module?
Thanks,
--- Jayesh
