For security reasons, IP phones support off hook hot line dialing feature, which allows
the phone to first dial out the pre-configured number when the user lifts the handset,
presses the speakerphone key/off-hook key or desired line key, dials out a call using the
account with this feature enabled. The SIP server may then prompt the user to enter an
activation code for call service. Only if the user enters a valid activation code, the IP
phone will use this account to dial out a call successfully.
Off hook hot line dialing feature is configurable on a per-line basis and depends on
support from a SIP server.
