Understanding Shared Lines

Remote-in-Use

The “In Use Remote” message and icon display on your phone when another phone that shares your line has a connected call and Privacy is disabled. You can place and receive calls as usual on the

shared line, even when the “In Use Remote” message or icon displays.

Sharing Call Information and Barging

Phones that share a line each display information about calls that are placed and received on the shared line. This information might include caller ID and call duration. (See the Privacy section for exceptions.)

When call information is visible in this way, you and coworkers who share a line can add yourselves to calls using either Barge or cBarge. See Using Barge to Add Yourself to a Shared-Line Call, page 54.

Barge—Allows you to join a shared-linecall with an IP phone that has the built-in bridge enabled.
