server group and
configure the server
information.

By default, a SIP server group has no
member server.
You can add at most five member
servers to a SIP server group. An index
represents the priority of a member
server in the SIP server group. The
smaller the index value, the higher the
priority.
5. Specify a name for
the SIP server group.
group-name group-name
Optional.
Not specified by default.
The name of a SIP server group identifies
the SIP server group. The domain name
of the carrier server is usually used as the
name of a SIP server group. If the name
of a SIP server group is not configured,
the host name specified in the assign
command is used to identify the group, if
any. Otherwise, the IP address or
domain name of the current server in the
SIP server group is used to identify the
group.
6. Configure a
description for the SIP
server group.
description text
Optional.
Not configured by default.
Enabling the real-time switching function
With the real-time switching function 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 registration
requests 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
has tried all the servers in the group.
With the real-time switching function enabled, 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 has tried all the servers in the
group.
