If you have SER in the public internet along with RTP proxy ( http://www.portaone.com/~sobomax/rtpproxy.tar ) then you can can deal with any symmetric SIP user agent behind NAT. In some cases SER will force RTP proxy, but it tries to minimize using the rtp proxy. I don't know if asterisk is symmetric, most existing sip phones are. SER can't be call stateful, it's a SIP proxy. Jan. _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
