Hotline
Hotline, sometimes referred to as hot dialing, is a point-to-point communication link in which a call is automatically
directed to the preset hotline number. If you lift the handset, press the Speakerphone key or the line key, and do
nothing for a specified time interval, the phone will automatically dial out the hotline number. Yealink phones only
support one hotline number.
Note: If you do not specify a line, the phone uses the first available line to dial out the hotline number by default.
This feature works only if the Off Hook Hot Line Dialing feature is disabled. For more information, refer to Off Hook Hot Line
Dialing.
