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 IP phone will automatically dial out the
hotline number. Yealink IP phones only support one hotline number.
