With Hotline/Warm-Line operation configured, the IP Phone automatically calls the defined destination
when you take the handset off-hook or press the speaker button. The call initiates immediately, Hotline,
or after a delay of up to 10 seconds, Warm-Line. The later permits you the time to access another feature
or line as needed. Note that with Hotline configured, Speed dial, redial and other automated dialing
features will not operate.
Operation of this feature is automatic.
