You or your coworker can join a call on the shared line. Your administrator needs to enable the feature on your phone.

If a user with whom you share a line has privacy turned on, you can't see their line settings and you can't add yourself to their call.


Press the line button for the shared line.


Enter *33 on your phone.


If set up this way, you'll hear a tone letting you know that the system recognizes the access code.


Enter the phone number of the person whose call you want to barge in to.


When connected, you're apart of the current call.
