When this field is specified, the phone will register with the primary
SIP registrar (The “Registrar” field) if it is accessible. If the primary
SIP registrar becomes inaccessible via UDP or TCP, the phone will
attempt to register with the backup registrar. If the phone
successfully registered with backup registrar, it will switch to the
backup registrar to perform outgoing calls and receive incoming
calls. While the phone is registered with the backup registrar, it will
monitor the primary SIP registrar connection. Once the primary SIP
registrar becomes available again, the phone will roll back to
register with the primary registrar and route SIP traffic from/to the
primary registrar.
Use Proxy for
Registration
Use this option to indicate whether or not the SIP proxy server(s)
specified in the Outbound Proxy field should be used when
registering. Select “Use Outbound Proxy” to have the system add
listed proxy servers to the route headers of the SIP REGISTER
request.
Outbound Proxy
Enter the outbound SIP proxy server’s IP address or name in the
Outbound Proxy field. If there are multiple SIP proxies, separate the
addresses by a comma. Also note that on the SIP Settings page
there’s an option to allow strict routing. If that option is set and you
have a SIP proxy that is configured for loose routing, add the “;lr”
designation after the proxy’s address, for example,
“10.134.129.101;lr”.
ID
ID is the phone’s SIP ID used for SIP registration. If this field is left
blank, the Username field will be used as the ID.
Display Name
Display Name is the string that is shown at the far side when you
make outbound calls. If you do not provide a Display Name, the
Username will be used. Please note that your IP PBX might
override the Display name sent by the FLX and replace it with
names configured in the PBX.

This is the username for the account used to authentication with the
SIP registrar and proxies.
Password
This is the password for the account used to authenticate with the
SIP registrar and proxies.
