If you have a shared line, you might see the
"in-use-remote" message on your phone screen
indicating that a co-worker is currently using the
shared line. You can place and receive calls as usual on
a shared line, even when the remote-in-use message
displays.

Maximum Supported Calls on a Shared Line

The maximum number of calls that a shared line
supports can vary by phone model. For example, your
Cisco Wireless IP Phone 7920 supports a maximum of
two calls on a shared line while your co-worker's
Cisco IP Phone 7960 can support four calls on the
same line. If there are two calls on the line, the
NewCall softkey is unavailable to you but is available
to your co-worker.
