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".
IP address or Domain name of Outbound Proxy, Media Gateway, or Session Border
Controller. Used for firewall or NAT penetration in different network environment. If
the system detects symmetric NAT, STUN will not work. ONLY outbound proxy can
provide solution for symmetric NAT.
User account information provided by VoIP service provider (ITSP); either an actual
phone number or formatted like one.

to or different from SIP User ID.

of ITSP.

The default is set to A Record. If users wish to locate the server by DNS SRV, users
may select SRV or NATPTR/SRV. When "Use Configured IP" option is selected, if
SIP server is configured as domain name, phone will not send DNS query, but use
"Primary IP" or "Secondary IP" to send sip message if at least one of them are not
empty.
This option applies only if "Use Configured IP" is selected, the phone will send DNS
query to the Primary IP. Insert IP address here.
Insert the first back up IP here.
Insert the second back up IP here.
Default is "Disabled". If the phone has an assigned PSTN telephone number, this
field should be turned on and a "User=Phone" parameter will be attached to the
"From" header in SIP request.
This parameter controls sending REGISTER messages to the proxy server. The
default setting is "Yes".
Default is "No". If set to "Yes", the SIP user‟s registration information will be cleared
on reboot.
