[OpenSER-Users] OpenSER Proxy to Asterisk & MESSAGE handler

[Ross Beer]

Hi All,
 
I am using OpenSER as a NAT proxy for asterisk and would like to use it to deliver SIP 'MESSAGES' between clients.
 
At the moment I have the following configuration however messages are not being sent to the other clients. Instead they are being passed to asterisk.
 
I would be very grateful if anyone could point me in the right direction.
 
Ross
