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>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>Where <a href="http://126.128.68.9:5060" target="_blank">126.128.68.9:5060</a>
is the Kamailio; <a href="http://126.128.68.8:5065" target="_blank">126.128.68.8:5065</a>
is a freeswitch playing music and the request is
received on <a href="http://126.128.68.9:8080" target="_blank">126.128.68.9:8080</a>
which is kamailio acting as a websocket server.</div>
<div>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?</div>

<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

the SIPML5.</div>

<div>What I can see is the SIPML5 from

<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

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>
