Server Redundancy Feature
Two secondary SIP servers may be configured. The 8190S will attempt to register with the
primary server but switch to a secondary server if necessary. The configuration allows re-
registration to the primary server upon availability or to stay with a server until
unresponsive.
Backup Server #1
Only visible if 'Server Redundancy Feature' is enabled. If primary server is unreachable
the 8190S will attempt to register with the backup servers. If enabled, the 8190S will
always attempt to register with the highest priority server.
Backup Server #2
Only visible if 'Server Redundancy Feature' is enabled. If backup server #1 is unreachable
the 8190S will attempt to register with the 2nd backup server. If enabled, the 8190S will
always attempt to register with the highest priority server.
Polling Intervals (seconds)
Only visible if 'Server Redundancy Feature' is enabled. 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
Only visible if 'Server Redundancy Feature' is enabled. 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
Only visible if 'Server Redundancy Feature' is enabled. Reconnect with higher priority
server once available, even if backup connection is still fine.
Polling Method
Only visible if 'Server Redundancy Feature' is enabled. SIP message used to poll servers
to monitor availability.
Keep-alive Method
If Double CRLF is selected the 8190S will periodically send a CRLF message for both
UDP and TCP connections to maintain connection with the SIP Server.
Keep-alive Interval
Interval in seconds that the CRLF message should be sent.
