This may or may not work for you but this is what we have:

Scenario:

4 inbound lines using a TDM 4 FXO and 4 SIP extensions.

when a call comes in on line 1 ( give a standard ring),
line2 (ring2) , and line3 etc...

exten => s-BUSY,6,Goto(40852,9)
;done
exten => 40852,9,Hangup

etc... etc... etc... for each extension.


What this does for us is to separate the rings coming from specific pots lines
could also be adapted to other lines (iax, etc...) I believe.

Hope this helps
