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.

1

Press the line button for the shared line.

2

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.

3

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


 

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