Availability not changing for extension-specific office hours

15.5. Update office hours for an extension to specific times.

None set for Friday - so it should set them as unavailable. Save settings, but extension is still available.

Hello @poynter.net

If you are setting the office hours on a Friday and leave the Friday hours blank the system will not switch all extensions to DND as the PBX did not receive a trigger to be able to switch the extensions to DND.
To provide a better example lets assume that you are setting office hours for Friday on a Friday at 09:00. You set the office hours to 08:00 to 17:00 and apply the changes. In this scenario the PBX will do nothing until 17:00.

The same hours are set at 07:00 the same Friday. In this scenario the PBX will set the extensions to Available at 08:00 as the change will be triggered by the office hours.
I hope the above make sense.
