numbers of lines depending on the phone model. See the
Phones" section on page 2
Each line corresponds to a phone number (or extension) used for calls. Each line
can support two calls. So, for example, a four-line phone can handle eight calls.
One call can be active (in conversation) and seven can be on hold.

Shared Line Appearances

Shared Line Appearance (SLA) allows multiple phones to share an extension
number and manage a call as a group. At any given time, each station sharing a call
appearance can monitor the state of the call appearance. A station can select a
shared call appearance to make a call only if the call appearance is not being used
by another station.
When a call is made to the extension number for the SLA, all sharing stations ring.
Any station can answer the call. If the active phone places the call on hold, the call
can be resumed from any of the sharing stations by pressing the corresponding
line key from another phone (Cisco SPA 303 and Cisco SPA 500 series, except for
the Cisco SPA 502G) or the Select button when the Resume icon is displayed
(WIP310).
