I am trying to achieve the same thing. I have bothe asterisk and X-lite behind NAT.
sip uses port 5060 X-lite can be configured to use an rtp port, and you can specify your external address... y configured my nat to foward 5060 to my * ports 8000 and 8001 too. I also tried with the sip with no nat. and my result where the same... I have 5 seconds of audio... so I guess there is another extra port involved in the operation, one which signals the communication status. does someone knows anything about this? is my guessing correct? thanks, alito ----- Original Message ----- From: Peter Zeltins <[EMAIL PROTECTED]> To: Asterisk Users <[EMAIL PROTECTED]> Sent: Monday, October 27, 2003 10:42 AM Subject: Re: [Asterisk-Users] SIP & IAX behind NAT > OK, I got IAX to work.
