Real-Time Switching
Enable or disable the real-time switching function. When the real-time switching
function is enabled:
• If the SIP trunk device receives no response message or receives
response message 408 or 5XX (excluding 502, 504, 505, and 513) after
sending a registration request to the SIP server, the SIP trunk device tries
to connect to the member server with the second highest priority value in
the SIP server group, and so on, until it successfully connects to a SIP
server or have tried all the servers in the group.
• If the SIP trunk device receives no response message or receives
response message 403, 408 or 5XX (excluding 502, 504, 505, and 513)
after initiating a call, the SIP trunk device tries to connect to the member
server with the second highest priority value in the SIP server group, and
so on, until it successfully connects to a SIP server or have tried all the
servers in the group.

Table 256 Configuration items
Item Description
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.
