Server Redundancy Feature
Two secondary SIP servers may be configured. The 8201 SIP PoE
Intercom will attempt to register with the primary server but switch
to a secondary server when necessary. The configuration allows re-
registration to the primary server upon availability or to stay with a
server until unresponsive.
If Server Redundancy is selected the web page will expand as shown
below.
Backup Server #1
If primary server is unreachable the 8201 SIP PoE Intercom will
attempt to register with the backup servers. If enabled, the 8201 SIP
PoE Intercom will always attempt to register with the highest priority
server.
Backup Server #2
If backup server #1 is unreachable the 8201 SIP PoE Intercom will
attempt to register with the 2nd backup server. If enabled, the 8201
SIP PoE Intercom will always attempt to register with the highest
priority server.
Polling Intervals (seconds)
Time period between sending monitoring packets to each server.
Non-active servers are always polled, and active server may
optionally be polled (see below).
Poll Active Server
Explicitly poll current server to monitor availability. May also be
handled automatically by other regular events, so can be disabled to
reduce network traffic.
Automatic Failback
Reconnect with higher priority server once available, even if backup
connection is still fine.
Polling Method
SIP message used to poll servers to monitor availability.
