Polling Method
Enable different ports for extensions for
certain proxies such as Cisco Communication
Manager 7, to send a page SIP request
through different port numbers.
Two secondary SIP servers may be configured.
The 8180 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 primary server is unreachable the 8180 will
attempt to register with the backup servers.
If enabled the 8180 will always attempt to
register with the highest priority server.
Time period between sending monitoring
packets to each server. Non-active servers are
always polled, and active server may optionally
be polled (see below).
Explicitly poll current server to monitor
availability. May also be handled automatically
by other regular events, so can be disabled to
reduce network traffic.
Reconnect with higher priority server once
available, even if backup connection still fine.
SIP message used to poll servers to monitor
availability.
