Actually you can do this a lot more simply without using Goto (which
might mess with your CDR):

exten => _404NXXXXXX,1,NoOp
exten => _770NXXXXXX,1,NoOp
exten => _678NXXXXXX,1,NoOp

exten => _NXXNXXXXXX,2,NoOp(Start of common instructions)
exten => _NXXNXXXXXX,n,etc....

Since there is an implicit 'Goto' from priority 1 to priority 2 anyway,
you might as well take advantage of it :-)
