[SR-Users] Help with SIP over Websocket audio call: 405 Method Not Allowed

[Brad Johns]

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:

Mar 29 20:16:07 ace /usr/local/sbin/kamailio[5928]: NOTICE: acc
