; Feature code prefix to allow FreePBX user to set and unset a dobro-callflow
; it works similarly to a Call Flow Conrol, except the phone user sets the
; destination number when enabling
; Latest version:
; Usage:
; Dialplan below goes in the file
; /etc/asterisk/extensions_custom.conf
; and then create a Custom Destination with the details indicated. The idea
; is that you have a dobro-callflow of an arbitrary sequence of digits, say 2000.
; you program a blf with "6502000" and create a Custom Destination with arg "2000"
; The user then dials the feature code to set the redirect and again to toggle off
