Keep-Alive Mode
The keep-alive function is used to detect whether the SIP servers in a SIP server
group are reachable. The SIP trunk device selects a server according to the detect
result and the redundancy mode. If the keep-alive function is disabled, the SIP trunk
device always uses the server with the highest priority in the SIP server group.
• Disabled—Disable the keep-alive function.
• Options—The SIP trunk device periodically sends OPTIONS messages to detect
the servers. If the SIP trunk device receives response message 408 or 5XX
(excluding 502, 504, 505, and 513) from a SIP server after sending an
OPTIONS message, it considers the SIP server unreachable.
• Register—The REGISTER message can be used to detect the SIP servers. If the
SIP trunk device receives response message 408 or 5XX (excluding 502, 504,
505, and 513) from a SIP server after sending a REGISTER message, it
considers the SIP server unreachable.

OPTIONS Messages
Set the interval for sending OPTIONS messages to the SIP servers when the
keep-alive mode is set to Options.
