[asterisk-users] Variable stripping/removing part of string

[magnus.b at inputinterior.se]

Now i am lost.
exten => 0424449631,n,NoOp(${CALLERID(name)})
exten => 0424449631,n,NoOp(${CUT(CALLERID(name),\(,2):0:-1})
-- Executing [0424449631 at fax.inputinterior.se:4] NoOp("OOH323/Avaya2-8", 
"Martela (fax)") in new stack
-- Executing [0424449631 at fax.inputinterior.se:5] NoOp("OOH323/Avaya2-8", 
"fax)") in new stack
But i am looking for the part before " (", in my case: "Martela"

You're almost there.  The issue is that CUT uses 1-based offsets, not
0-based offsets, so:
exten => 0424449631,n,NoOp(${CUT(CALLERID(name),\(,2):0:-1})
