Home server
A Home server handles SIP requests for the specific domain assigned for this server. The
Home server also forwards any requests pertaining to other domains to the Edge server. One to
20 Home servers and exactly one Edge server is required in this scenario. Each Home server
can support up to 15,000 SIP users. Home servers can be duplexed for local failover.
Home/Edge server
A combined Home/Edge server performs the functions of both a Home server and an Edge
server for an enterprise. This is a single-server scenario. That is, no other Home or Edge
servers can exist in this architecture. Home/edge combined servers can be duplexed for local
failover.
