I have been working on kamailio with following scenario:

1. Webrtc SIP Users register to Kamailio

2. Users initiate outgoing calls to some other numbers 

3. Kamailio dispatches outgoing calls to Asterisk 

4. Asterisk answers the call and then send a text message to the caller using SendText, which was working fine a few days back but all of sudden it has stopped working

5. At Asterisk end it is showing that message was delivered successfully but when I check SIP user logs, there is no message event.

Please review my config file at following URL:

Developers, I also want to know if there is any way to log text message in kamailio server.
