Night Service Button (#503)

Use this feature to program a button on the system telephone at extension 10 to turn Night
Service on and off. When Night Service is on, all lines and pools assigned to the telephones of
the users in the Night Service Group ring immediately, regardless of their normal Line Ringing

Night Service is useful if you want phones to ring after regular business hours. For example,
although Shipping Department workers do not answer calls directly during the day, you want them to answer incoming calls after hours.

  • You must program a Night Service Button on the system telephone at extension 10.
  • Program Night Service on a button with lights. This feature is not supported on a button
    without lights.
  • Dialing restrictions for extensions not in the Night Service Group remain the same as during normal daytime operation.
  • If you reassign the Night Service Button, it is removed from the button where it was
    previously assigned.
  • If you program a System Password (#403), you must enter the password when turning Night Service on or off. In addition, when Night Service is on, users in the Night Service Group can dial only numbers on the Emergency Phone Number List (#406) and Marked System Speed Dial numbers without entering the System Password. Night Service with a System Password is useful for controlling unauthorized use of phones after hours.
  • If you have a voice messaging system, VMS Hunt Schedule (#507) determines when outside calls should ring the VMS Hunt Group (always, day only, or night only). The status of the Night Service Button at extension 10 tells the voice messaging system to operate in day or night mode.
  • The Night Service Button returns to the status (on/off) it was in immediately prior to a power failure or to System Reset (#728) being used.
  • Night Service is unavailable on T1 lines with Direct Inward Dialing (DID).
