Description
"Line" key can behave as a private line or shared line key,
according to the setting user_shared_line.
Private Line (user_shared_line = "off"):
This key can be used for:
SIP Identity Mapping:

This allows the customer to use different SIP
identities (accounts, registrations, lines) similar as
having several PSTN phone lines. Local SIP
identities (lines) can be assigned to programmable
keys from the list as Context via key Type "Line".
Free Key:

Line is also the default setting for the Freely
Programmable LED Keys P1–P12. If no argument
is set, the keys are treated as free. Outgoing and
incoming calls not bound to any other key go to the
first such key that is not already occupied.
Shared Line (user_shared_line = "on"):
The Bridged Line Appearance (BLA) feature allows
subscribers to share SIP lines and also provides status
monitoring of the shared line. The BLA feature is commonly
offered in the IP Centrex services and IP-PBX offerings.
When a user places an outgoing call using such an
appearance, all members belonging to that particular BLA
group are notified of this usage, and are blocked from using
this line appearance until the line goes back to idle state or
if the call is placed on hold. Similarly, all members of the BLA
group are notified of an incoming call and the call can be
picked up on a line appearance associated with the BLA
extension.
BLA members can monitor the status of the bridged line via
the Function keys available on the VTech phones. For
monitoring the status of a bridged line, the function key
must be configured as a "Line" type. In addition, the
"Number" must be set to the bridged line resource URI, and
the "Context" must be set to a specific identity (not "active").
Once the phone has registered and subscribed
successfully for the BLA resource, the LED corresponding
to the programmed function key indicates the status of the
bridged line. LED "on" indicates the line is in use, while
LED "off" indicates an idle status.
