Activating this feature allows an extension to automatically access a nominated resource by simply going off-hook. The activation can be immediate or after a delay of up to 9 seconds. The delay allows the user to dial something before the hotline feature takes effect. The hotline resource can be:

• another extension
• an exchange line or trunk route
• an abbreviated number
• a pickup or paging group or a UCD number

The hotline feature can be active during day mode only, night mode only or always.
