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.
