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

Where 126.128.68.9:5060 <http://126.128.68.9:5060> is the
Kamailio; 126.128.68.8:5065 <http://126.128.68.8:5065> is a
freeswitch playing music and the request is received on
126.128.68.9:8080 <http://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,

Hello All,
I have a setup which is SIPML5 -> Kamailio(Websocket) ->
Freeswitch. All I am trying to do is initiate a call from
SIPML5 and Play a Music file from freeswitch. This works, but
the call hangs up after 30 seconds due to ACK timeout from
from the SIPML5.
What I can see is the SIPML5 from Chrome does send an ACK on
websocket, but I see the following error in kamailio syslog:
*via_builder(): TCP/TLS connection (id: 0) for WebSocket
could not be found*
*ERROR: <core> [msg_translator.c:1725]:
build_req_buf_from_sip_req(): could not create Via header*
*ERROR: <core> [forward.c:607]: forward_request(): ERROR:
forward_request: building failed*
*ERROR: sl [sl_funcs.c:371]: sl_reply_error(): ERROR:
sl_reply_error used: I'm terribly sorry, server error
occurred (1/SL)*
Can someone help me understand what I am missing here and why
kamailio is not able to create a VIA header to forward this
request towards freeswitch. I have built a simple config file
by following https://gist.github.com/jesusprubio/4066845 as
reference.
Any help in understanding this is really appreciated.
looks like
the web rtc connection was down (closed by one side
or interrupted by the network). You can check with kamcmd the
list of active connections.
Cheers,
Daniel
