Use Night Service to reroute calls after hours.
Night Service redirects outside calls to their night mode destination. Typically, the attendant or supervisor activates Night Service after normal working hours, when most employees are unavailable to answer calls. Lines can ring extensions directly at Night, providing specific answering points for Night Service calls. (For example, you can program lines to ring the security station at night.)
To have outside lines ring the External Paging system (which users can answer by dialing a code), see Outside Call Ringing Over External Page in Paging. To have the ringing call also activate the system relay, see Page Relay Control in Paging.
These are the available answering options for a line. The same options are available during the day and when the system is in the night mode.
