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.<br>
<br>
Get the log messages with debug=3 in order to see what is happening.<br>
<br>

<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>Also the connection between Kamailio and Freeswitch

<div>Hello All,</div>
<div>I have a setup which is SIPML5

initiate a call from SIPML5 and Play a

works, but the call hangs up after 30
seconds due to ACK timeout from from
the SIPML5.</div>
<div><br>

<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>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

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>
