Fellow asterisk users,

I am trying to get Single Line Appearance functionality working on a set of Linksys SPA942 phones and have not been successful. It looks like sla.conf is not getting read, only one phone reads as registered for the shared line, and a busy tone every time the shared extension is dialed. I have followed the documentation [1] and followed through other threads I saw regarding this feature [2,3,4]. Any advice would be appreciated.

Sincerely, Dennison Williams

; ==; = sla.conf
; ==[line1]
type=trunk device=SIP/240 ; The example show using a DHADI trunk, but I can use a sip line right?
