Hi I'm new at using OpenSER. I plan to use OpenSER with a SIP proxy (rtpproxy?, mediaproxy?) in order to handle SIP client registrations and connections behind NAT, and then I want to pass the control to an Asterisk server, in order to make the call over an IAX trunk. I've been reading quite a lot documentation on both SER and OpenSER, but I can't figure out how to do it properly. Is there an example or a guide I can check? Thanks in advance. -- Saúl -- "Some people say why, other just say, why not." http://saghul.wordpress.com/
