Advanced Call Handling
Cisco Unified IP Phone User Guide for Cisco Unified Communications Manager 8.6 (SCCP and SIP) 5
Tip
Logging out of hunt groups does not prevent non-hunt group calls from ringing your phone.
Using a Shared Line
Your system administrator might ask you to use a shared line if you:
Have multiple phones and want one phone number
Share call-handling tasks with coworkers
Handle calls on behalf of a manager

Understanding Shared Lines

Remote-in-Use Icon

The remote-in-use icon appears when another phone that shares your line has a connected call.
You can place and receive calls as usual on the shared line, even when the remote-in-use icon appears.

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 5.

Privacy

If you do not want coworkers who share your line to see information about your calls, enable the Privacy
feature. Doing so also prevents coworkers from barging your calls. See Preventing Others from Viewing
or Barging a Shared-Line Call, page 7.
Note The maximum number of calls that a shared line supports can vary by phone.

Using Barge to Add Yourself to a Shared-Line Call

You can use barge features (cBarge or Barge) to add yourself to calls on your shared line. (Calls must
be non-private calls. See Using a Shared Line, page 5.)
