Algo 8180 User Manual page 53

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 8180 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.
Use Outgoing TLS port in SIP headers
Use ephemeral port number from outgoing SIP TLS connection instead of listening port
number in SIP Contact and Via headers. This is useful to connect the device to some local
SIP servers, like Asterisk or FreeSWITCH.
Do Not Reuse Authorization Headers
When enabled, all SIP authorization information from the last successful request will not
be reused in the next request.
