Monitor Time Condition Status
A time condition determines whether the system is treating the current moment as Business Hours, Outside Business Hours, or a Holiday, and inbound routes send calls to different destinations accordingly. If you assign a Busy Lamp Field (BLF) key on a user’s IP phone, that user can see the active status at a glance and tell where incoming calls are currently going.
There are two ways for a user to keep an eye on the time condition:
- On the desk phone. Program a BLF key on the extension’s phone. This page covers that method.
- On the Operator Panel. Users who are allowed to override the time condition on the Operator Panel can also view the current status there.
The BLF setup differs slightly depending on how the matching inbound route decides its schedule. Use the section below that matches your configuration.
Prerequisites
Section titled “Prerequisites”Before you add the function key, the target IP phone must already be connected to the PBX (Private Branch Exchange, your phone system) and linked to the user’s extension through auto provisioning. If you have not done that yet, set it up first:
Inbound route based on Global Business Hours
Section titled “Inbound route based on Global Business Hours”Use this when the inbound route follows Business Hours configured in the system’s default time zone.

The status is switched with the Switch Business Hours and Holidays Status feature code, which is *99 by default. That is the value you monitor.
