Log in to the Web Interface, and go to SIP, input settings, then Lines and input settings. The settings to change from the factory settings would be:

SoundPoint IP SIP Settings
Setting Value
Proxy address: voiceless.aa.net.uk
Server 1: voiceless.aa.net.uk
SoundPoint IP Line Settings
Setting Value
Display Name: Your name, etc.
Address: your-number@voiceless.aa.net.uk
Auth User ID: Your Number
Auth Password: Your Password
Label: Your Number




NTP server setting is ignored, and phone only tries to set time from its default gateway so you need to have an NTP server or portmap to an NTP server on your local router. Without this, the screen constantly flashes the time which is annoying.

Requires a reboot after changing SIP proxy or Line settings.
