Description The address of the registrar for which the IP phone uses to send REGISTER requests.
A SIP registrar is a server that maintains the location information of the IP phone.

can dial using username@ip address of the phone.
If the Registrar IP address is set to 0.0.0.0 for a per-line basis (i.e, line 1, line 2, etc.), then
the register request is not sent, the "No Service" message does not display, and the mes-
sage waiting indicator (MWI) does not come on.
