Configuring Proxy IP and Proxy Port:
5. In the Proxy Server field, enter an IP address or fully qualified host name in the Proxy
Server field. Default is 0.0.0.0.
6. In the Proxy Port field, enter a Proxy Port number in the Proxy Port field for accessing
the SIP proxy server. For example, 5060. Default is 0.
Configuring Registrar IP and Registrar Port:
7. In the Registrar Server, enter an IP address or fully qualified host name in the Registrar
Server field. Default is 0.0.0.0.
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 mes-
sage waiting indicator (MWI) does not come on.
8. In the Registrar Port field, enter a Registrar Port number in the Registrar Port field for
accessing the SIP registrar server. For example, 5060. Default is 0.
