I think you are over thinking this.  We set our Asterisk server up with 
multiple outgoing dial rules to handle local and long distance.  Keep in 
mind that we are connected to SIP provider that takes care of some of 
this for us.

Our local extensions are 2**

I have outgoing call rules similar to

exten = _NXXXXXX!,1,Dial(outgoing sip connection)   ( this is for local 
calls )
exten = _NXXNXXXXXX!,1,Dial(outgoing sip connection)  ( this is for long 
distance calls )
exten = _911!,1,Dial(outgoing sip connection)  (this is of course for 
dialing 911 )
exten = _011XXXXXX.,1,Dail(yada yada yada)  (interntional calls)
exten = _1NXXNXXXXXX!,1,Dial(Yada yada yada )  (long distance with a 1 
in front.)

If you have to have a 1 on front of your long dist numbers ( we don't ) 
leave off the _NXXNXXXXXX! pattern and only use the last one.

Asterisk will now look at the relevant extensions and decide which to 
use.  Using this method if you mis-dial then the phone line does not get 
used and Asterisk sends a failed number sound.  If you dial 3 numbers it 
will look at the local extension you have set up and if the one you 
dialed exist it dials it.  If you get an error.  If you match the patern 
above it dials out.  The only time with this system you would have a 
problem is if you make your internal extensions 7 or 9 digits.

Doing like I have above Asterisk will match your pattern more based on 
ext length than on what order the numbers are in.

Hope that helps
