• [Re-Register]: Re-REGISTER all activated SIP address-of-records to SIP service again
without user confirmation
.
If the user has gone off-line (see below) explicitly, restart the auto-registration process to let
user go online again.
• [Logout]: Goes off-line
without user confirmation.
Unregister all SIP address-of-records to all activated SIP service immediately and stop the
regular auto-registration scheduling to keep user offline. The phone will keep unregistered until
the “Re-REGISTER” command is issued to go online explicitly. This is useful when you are off
work and want all calls go directly to ring your home lines.
