Peter,
Thank you. By changing the "method_filtering" modparam to 0 (it was
actually 1), I am now able to make it past this, and the INVITE is
processed over WS transport. However, the audio call is still not
completing.
I am seeing a "180 Ringing" message for a while, followed by a "408
Request
Timeout". Nothing is showing ringing on the remote browser with JsSIP
tryit.
The only clues I can see in /var/log/syslog hae to do with Accounting DB.
I am using MySQL.
Note that I can do SIP User Agent client calling just fine between these
two same users, and using the JsSIP Tryit app I can also do 'chat'
messaging. Just can't do audio call. Here is /var/log/syslog:

Hello,
In SIP you can put an Allow: header in REGISTER requests to say which
methods the registering end-point is capable of receiving.
If you get a -2 returned from lookup() it means that the method for the
request (in this case INVITE) was not in the "Allow:" header in the
REGISTER.
You can check this by looking at the REGISTER request in a trace and by
inspecting the location records stored in Kamailio (use the ul.dump
command in kamctl for this).
You can disable method filtering in the Kamailio registrar module by
ensuring that the "method_filtering" modparam is set to 0 (or just not set
at all as disabled is the default). Doing this should prevent lookup()
ever returning -2.

Peter
Hi,
New to Kamailio. I have my Kamailio 4.0 server with websocket support,
and
the users can register using the JsSIP Tryit sample WebRTC application.
They can do 'chat' feature of JsSIP Tryit using kamailio 4.0 sip over
websockets module.
However, after registration, the users can't place an audio call. I see
no
ringing on the remote browser. Can anyone help with clues or debug? In
Debug log I can see the websocket ws_frame.c decode the websocket message
into SIP, and I see normal SIP call flow for an INVITE. However, nothing
indicating a call.
I ran 'ngrep -p -w -W byline port 8888' (WS port) and see that I'm
getting
an error response to browser UA of "405:
Method Not Allowed". I've
isolated it down to the this snippet in the kamailio.cfg for
route[LOCATION]:
$avp(oexten) = $rU;
if (!lookup("location")) {
$var(rc) = $rc;
route(TOVOICEMAIL);
t_newtran();
switch ($var(rc)) {
case -1:
case -3:
send_reply("404", "Not Found");
exit;
case -2:
send_reply("405", "TEST: Method Not
Allowed");
exit;
}
}
The switch case is returning -2, for some reason.
Any help in debugging this appreciated.
