Users can switch in or out of Night Service mode by dialing the appropriate short code. Calls are presented to a Night Service group. This can be controlled automatically by setting a time profile which defines the hours of operation of the main group or manually using a phone feature code. During Night Service mode, the original hunt group is temporarily disabled. You can design callers to the hunt group to do any of the following actions:

• Pass to a Night Service Fallback group passing calls to a manned extension or external number.

• Be played the Out of Hours greeting if set in voicemail.

• Receive a busy tone.
