Configuring Basic Features

197

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 presses the

speakerphone key or desired line key (pressing line key is not applicable to SIP-T19(P)

E2 IP phones), dials out a call or goes off hook the phone 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.

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.

This feature is also applicable to the IP call and intercom call.
