[asterisk-users] Shared Line Appearances

[Pavel Jezek]

anyone using/experimenting with this new feature in asterisk 1.4?
is anybody able to post some info how to use and what features are 
supported?
I have general knowledge how SLA should work, ie. monitor status of 
another line like BLF with additional features like answer ringing call, 
barge into existing call on shared line and make conference call or 
resume call, that was put on hold on another phone sharing line....

as I look in sla.conf.sample, seems, that when Dial(SIP/junky) from 
example, this will ring both defined phones,
but what other features of SLA asterisk will support (like barge, shared 
line status indication)?
I would like to use this feature on linksys942, because this phone 
doesn't support BLF, so maybe SLA will help me ;-)

; define a SLA called junky
[junky]
trunk => SIP/10
station => SIP/15
station => SIP/16
