<div dir="ltr">Hi,<div style>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?</div>

<div>Hello All,</div>
<div>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.</div>
<div><br>
</div>
<div>What I can see is the SIPML5 from Chrome does send
an ACK on websocket, but I see the following error in kamailio
syslog:</div>
<div><br>
</div>
<div><b>via_builder(): TCP/TLS connection (id: 0) for WebSocket
could not be found</b></div>
<div><b>ERROR: <core> [msg_translator.c:1725]:
build_req_buf_from_sip_req(): could not create Via header</b></div>
<div><b>ERROR: <core> [forward.c:607]: forward_request():

<div><b>ERROR: sl [sl_funcs.c:371]: sl_reply_error(): ERROR:
sl_reply_error used: I'm terribly sorry, server error
occurred (1/SL)</b></div>
<div><br>
</div>
<div>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 <a href="https://gist.github.com/jesusprubio/4066845" target="_blank">https://gist.github.com/jesusprubio/4066845</a>
as reference.<br>
</div>
<div><br>
</div>
<div>Any help in understanding this is really appreciated.</div>

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.<br>
