Configuring Lines

Cisco Small Business SPA300 Series, SPA500 Series, and WIP310 IP Phone Administration Guide

The Cisco SPA IP Phones (also called
numbers of lines depending on the phone model. See the
Phones" section on page 12
Each line corresponds to a phone number (or extension) used for calls. Each line
can support two calls. 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 (Cisco SPA303 and Cisco SPA500 series, except for the Cisco SPA502G)
or the Select button when the Resume icon is displayed (WIP310).
The Cisco SPA300 Series and Cisco SPA500 Series IP Phones support the private
hold feature for MetaSwitch and BroadSoft. Users who have a shared line can
press the PrivHold softkey, and the call can only be resumed by the user who
placed the call on hold.
