Phone Registration
Registration methods of the fallback mode include:
Concurrent registration: The IP phone registers to two SIP servers (working server
and fallback server) at the same time. In a failure situation, a fallback server can
take over the basic calling capability, but without some of the advanced features
offered by the working server (default registration method).
Successive registration: The IP phone only registers to one server at a time. The IP
phone first registers to the working server. In a failure situation, the IP phone
registers to the fallback server.
When registering to the working server, the IP phone must always register to the primary
server first except in failover conditions. When the primary server registration is
unavailable, the secondary server will serve as the working server.
