Think about that problem if you will for a moment. 2 SIP UAs are behind the same firewall. They connect out and the ITSP sees it is the same IP. You effectively have a 2 NAT problem. Unless your firewall is smart enough to route the 2 calls itself, you will have a problem. UA 1 tries to connect to caller at $outside_ip, and firewall goes, you can't connect here because I have 4 possible options and do not know where to go. ITSP tries in reverse, and UA 2 ends up in the same boat. Plus for you to think about, same basic problem exists, intra office calls would rely on the internet for any routing info. Internet down and no calls make it anywhere. Bad design to outsource your interoffice calls to someone on the internet. -- Steven Critchfield [email protected] --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "NLUG" group.
