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:
