Off Hook Hot Line Dialing

For security reasons, the phones support off hook hot line dialing feature, which allows the phone to automatically
dial out the pre-configured number when you lift the handset, press the Speakerphone key or desired line key. The
SIP server may then prompts you to enter an activation code for call service. Only if you enter a valid activation
code, the 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 the support from a SIP server.
The server actions may vary from different servers.
It is also applicable to the IP call and intercom call.
Note : Off hook hot line dialing feature limits the call-out permission of this account and disables the hotline feature. For
example, when the phone goes off-hook using the account with this feature enabled, the configured hotline number will not be
dialed out automatically.
