Warm Dial is a feature (since firmware version 10.1.26.0) that initiates an automatic call to a pre-configured number if no other number is dialled after a configured time out (e.g. fifteen seconds) once the phone goes off hook.
You can set the destination and time period on the WUI:
- Auto Dial Timeout (<auto_dial>): any value between 3 to 2147483647 seconds. Default value is off. Any value below 3 will trigger a Hot Dial.
- Auto Dial Target (<auto_dial_target>): Any valid phone number
