Hi, I am trying to create a small VoIP test environment, using the SPA9000. I have a small, private, routed IP network (a couple remote sites over a Frame Relay network). Again, no ISP, all private addressing and private routers and switches. I would have the SPA9K PBX at main site, along with a few phones, all on same VLAN/subnet. I would like to have a couple more phones at each remote site, obviously on different LANs and subnets. Security is not a concern, just wondering if the remote phones could register and use the services of the SPA9K. They will of course have IP connectivity. Does anyone know if this would be supported with one SPA9000 system? Bottom line is I want to make VoIP calls from remote site to main site (again, no ISP or ITSP involved). Thanks so much for any comments.
