Am I correct in assuming that all calls from each organization would route through our Asterisk server & be passed off to the service provider
That depends on your setup, on the provider and on the organization. If all support ReInvites and have them enabled, then it will work and the RTP traffic will flow between the organization and the provider. But each organization needs to be reachable via a public IP (i.e. not NAT) and the provider you use must support it too. I believe most(?) do, but you should check. --Luki _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
