You can access and change the AutoHours Settings from both the Web Console on the "System Settings" Tab, as well as from the "AuToHours" tab on the application settings.
AutoHours Feature
The IVM AutoHours schedule can be used to make IVM answer automatically only after business hours, to use different OGMs at different times of day or to change the number of rings to wait for at different times of day. This will save you having to manually turn IVM On/Off or select OGM every day.
To use AutoHours tick the "Use AutoHours" box and enter the applicable hours for weekdays, Saturday and Sunday. Then select what you want IVM to do between these hours and what you want IVM to do outside these hours.
Typical settings for a normal business offices are:
Weekdays: 09:00:00 to 17:00:00
Saturday: 09:00:00 to 12:00:00
Sunday: 00:00:00 to 00:00:00
Between these hours: Do not answer calls
After hours: Answer with default OGM
Similar results can be obtained using the Date-Time Validity Checking, but the system-wide AutoHours Settings are simpler. But if you are looking to setup a system that is more complex than the AutoHours feature allows you should see Date-Time Validity Checking.
