As far as i understand, Kamailio is probably in a Datacenter somewhere and the Asterisk box is in an Office without any public IP address forwarding data directly to the Asterisk. The best solution I can think of (in terms of security and ease of use) is using a VPN between Kamailio and your client's Asterisk box. Kamailio would forward all SIP messages to Asterisk via the VPN connection (OpenVPN is a very good solution) and RTPEngine would also have to be set up on the Kamailio box.
Without a VPN, you could use the Contact of Path modules and have your Asterisk register on Kamailio, but you would have to do some code because of the NAT issues. I would keep things simple, set up a VPN and have Kamailio and Asterisk "think" they're on the same network. *Sérgio Charrua* *www.voip.pt <http://www.voip.pt/>* Tel.: +351 <callto:+351+91+104+12+66>21 130 71 77 Email : *sergio.char...@voip.pt <sergio.char...@voip.pt>* This message and any files or documents attached are strictly confidential or otherwise legally protected.
