You can use this feature to play different auto-attendant greetings and options depending on the time of day. For instance, if your office closes at 6 PM and a caller dials in after that time, he or she could be greeted by a message saying “Thank you for calling, our office is now closed.” If that caller wishes to contact the sales department, they would be told that the sales department is closed and that they should leave a voicemail message.
An alternative approach would be to have calls sent to different staff depending on the time of day. Some businesses and organizations need to be available 24 hours a day, and day/night modes allow administrators to choose which staff will field calls during regular business hours and which staff will handle after-hours calls. This strategy can provide the best of both worlds, by ensuring you’re always available to clients but also that the call volume is shared fairly throughout the day based on “shifts.”
This feature is a function of your auto-attendant.
