Call Holding
Description
Call holding is a feature that allows a person to pause and resume an ongoing call
without terminating the line.
Getting Started
The Call Holding feature is available by default on the UCM. No additional
configuration is necessary.
Using the Service

• A and B are extensions registered to the UCM.
The service can be used as such:
1. B calls A.
2. A starts ringing and picks up the call.
3. Call between A and B is established.
4. A presses the hold button.

system’s configuration. No audio from either party can be heard.
6. A presses the hold button again to retrieve the call.
7. A and B can hear each other again.
