Cool.

Isn't this already supported with the built-in callgroup/pickupgroup 
functionality?

In the example you quoted, you would be looking at something like this:

exten => _20X,1,...          ; dial, etc.
exten => 720,1,Pickup(20)    ; the non-unique digits of the dialed
                                ; number

This example is a total of 11 dial-able numbers 200-209, and 720.  All 
extensions you might want to call pickup on have the common digits 20 
and one unique digit.  Pickup expects only the common digits when 
performing this type of action.

for your example:

exten => _9[0-7]X,1,...      ; dial, etc.
exten => 790,1,Pickup(9)     ; the non-unique digits of the dialed
                                ; number

This example is a total of 81 dial-able numbers, 900-979 and 790.  All 
extensions you might want to call pickup on have the common digit 9 and 
two unique digits.  Again, pickup only wants the common digits for this 
type of operation.
