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

20 Jun 2008


      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.
