Shared Line Appearence
From Snom Asterisk Portal

Feature Description
The Shared Line Appearance feature allows subscribers to share external lines (VoIP, ISDN, PSTN, ..) and also provides status monitoring of the shared line. When a user places an outgoing call using such an appearance, all members belonging to that particular SLA 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 SLA group are notified of an incoming call and the call can be picked up on a line appearance associated with the SLA extension.
You can also share lines in Asterisk without the Shared Line Appearance feature, but with SLA it is possible to select a desired outgoing line via a BLF key before you start dialing, which can be very handy in daily work.
Configure Asterisk
The support for Shared Line Appearances was introduced in Asterisk 1.4.0 but did not work correctly. Please use Asterisk >= 1.4.1 to use Shared Line Appearances.
As Asterisk is a media gateway with many channel drivers, the configuration and usage of Shared Line Appearances is a bit complicated. (you need to define SLA trunks, SLA users/stations and a mapping between both)
The configuration and usage of Shared Line Appearances is described very detailed on the Asterisk Website.
