# Call Rerouting First Alternatives

## Purpose

The Call Rerouting First Alternatives form is used to specify the routing information for the first alternative rerouting. The routing information is defined based on:

- the condition at the called number that caused rerouting (busy/do not disturb, or no answer) and

- the device from which the call originated (DID trunk, tie trunk, CO trunk, or internal call).

Use this form for the following tasks:

- Programming Call Rerouting

- Program Auto Attendant

- Program Night Service - Automatic
