[asterisk-users] Avaya 4620 SW SIP Config - not setting Proxy/Registrar

[Atlanticnynex]

I'm using the latest SIP firmware from Avaya. The phone receives the
46xxsettings.txt OK, and then after entering extension and password it
goes to the home screen saying 'Registering'. When I check
options->ViewIPSettings->IPAddresses on the phone,
the registrar and SIP Proxy fields are blank.

I have both lines: SET SIPREGISTRAR "67.1XX.XX.XX" and SET
67.1XX.XX.XX:5060;transport=udp  in 46xxsettings.txt so I'm not sure
why they are empty.

Also, what username/password will it use for registration/calls? There
is no config examples for the line accounts.
Does anyone have any *working* example configs?
