In the example, I believe the OP was using n algebraically to show the 
areas between 2 and 33 without realizing that n was in fact a valid 
priority number.

Roderick, yes, you can use Goto or GotoIf to skip entire sections of 
dialplan logic.  You either need to number your priorities fully or use 
labels with your n's if you choose to use n priorities.

exten => s,1,
exten => s,2,Goto(s,4)
exten => s,3,
exten => s,4,

OR

exten => s,1
exten => s,n,Goto(s,superjump)
exten => s,n
exten => s,n(superjump),

I believe that's how it works, but it's from memory, so might not be 
quite right.
