Call Forwarding
Description
Call forwarding is a feature that allows an endpoint to redirect calls to another phone
number or extension, minimizing the chances of a call going unanswered.
Getting Started
The Call Forwarding feature is available by default on the UCM. To use it:
1. Navigate to Extension/Trunk->Edit Extension and navigate to the Features
tab.
2. Configure the Call Forward Unconditional, Call Forward No Answer, and Call
Forward Busy fields with the desired settings.
(Optional). Enable the call forwarding feature codes by navigating to Call
Features
→
Feature Codes and clicking on the DND/Call Forward tab. This allows users
to enable and disable specific call forwarding settings by entering a code.
Using Call Forward Unconditional
Call Forward Unconditional redirects all calls immediately to the configured
destination.
Assuming the following:
• A, B, and C are SIP extensions registered to the UCM.
• A has Call Forward Unconditional set up to redirect calls to B.
The service can be used as such:
1. C calls A.
2. A does not ring, and the call s redirected to B.
3. B rings and picks up the call.
4. Call between B and C is established.
Using Call Forward No Answer
Call Forward No Answer redirects calls upon ring timeout to the configured
destination.
Assuming the following:
• A, B, and C are SIP extensions registered to the UCM.
