We are using call manager 18.104.22.168 and its running fine but just a small option which i am not able to find is when i am on phone and some body calls me he hears ringing tone where as i m busy on some other phone. So the users assumes i m not answering the calls. If someone can please tell me from where i can enable this option that if someone is busy the caller shold get the busy tone where as called party should get a notification. Thanks a Ton in adv.
Go into the line appearance on the phone and scroll down to where you see "Multiple Call/Call Waiting Settings on Device (mac address)" Then set your busy trigger to a "1".
