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.
A global value of 0.0.0.0 disables registration. However,
the phone is still active and you 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 message waiting indicator (MWI) does not
come on.
