- Access your call manager and click on Feature-Call park. Please create a Call park Number/Range.
- Click on Service-Service parameters, click on your Call manager's Ip address or name, select Cisco Call manager.
- In the Configured Service Parameters Box, you will find the parameter: CallParkReversionTimeout.
- Type the desired value in seconds in the value field and click on update.
- Try to make a phone call from one IP Phone to another one, and if you want to park that phone call, click on. If you don't pick it up, your phone will ring in the number of seconds that you specified. If you want to pick it up, just dial the Call park number.
This is the only feature available right now.
