Hey Guys, just looking for some input on this, thanks! Basic Topology ------------------------------- Core Route Servers - Server A, B Registration Server, Collects USRLOC which all reports to the SAME DATABASE. Server C (User A initial registration server) User A -> it will tell me location Server D User A -> it will tell me location Any complications, I should be aware of? So Call Flow will look like so: INBOUND CALL: (Server A|Server B) -> (Server C|Server D) -> (END USER) Now should I be weary of any "lockings" such as a client end such as cable/dsl modem, the ata itself, etc? Thanks. -- Brandon Armstead
