**Call flow control** is a switch with two states, **Active** and **Passive**. Calls go out of the matching path. Change the state by dialling the object's internal number or from the Webphone.

Use it to close the office early, switch to an emergency message, or override your normal [Time conditions](https://kb.voipcloud.online/au/pbx/conditions/time-conditions/).
