Off Hook Hot Line Dialing
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/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.
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.
The server actions may vary from different servers.
It is also applicable to the IP call and intercom call.
