Secondary SIP
Server
This field contains the URL or the IP address of a second SIP server.
When this field is configured, GXP2124 will send out Registration requests and
Subscribe messages (except for message waiting) to the “SIP Server” and
“Secondary SIP Server” for the same account.
When making a call, GXP2124 will use the registered primary “SIP server” first. If this
primary “SIP Server” is not available, the registered “Secondary SIP Server” will be
used.
If the primary “SIP Server” is not registered but “Secondary SIP Server” can be
registered, GXP2124 will use the “Secondary SIP Server” directly when making a call.
Note:
Please do not configure duplicate SIP Server address in “SIP server” and
“Secondary SIP Server”.
