Shared Line Appearances
Shared Line Appearance (SLA) allows multiple phones to share an extension
number and manage a call as a group. Cisco IP phones support SLA in association
with a BroadSoft application server.
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 (SPA9X2) or the Select button when the Resume icon
is displayed (WIP310).
The Cisco SPA525G supports 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.
Each station with an SLA can be configured independently. Although the account
information is usually the same for all of the stations, settings such as the dial plan
or the preferred codec can vary.
