asterisk users - Sep 2003 - Request for best practices

We are trying to implement "area-code dialing" in our asterisk PBX. 
Basically: we will have a number of customers, who may be in different area 
codes, that want to direct-dial each other's extensions. We want this to 
work like a "real" centrex, in that seven-digit numbers should try (1)
"local" VoIP extensions, and then (2) "local" PSTN numbers.
Ten-digit
numbers should dial (1) "long-distance" VoIP extensions, and then (2) 
"long-distance" PSTN numbers.

Here's my plan so far, does anyone have a better way? Will Goto() work the 
way I expect it to (i.e. will the extension I specify be pattern matched)?

==Extensions.conf=
[area555]
exten => _NXXNXXX, 1, Goto(extensions,555${EXTEN})
include => extensions

[area666]
exten => _NXXNXXX,1, Goto(extensions,666${EXTEN})
include => extensions

[extensions]
exten => 5551234567, 1, Macro(stdexten, 1234, SIP/user1)
exten => 6661234567, 1, Macro(stdexten, 1235, SIP/user2)
include => longdistance

[longdistance]
exten => _NXXNXXXXXX, 1, Dial(${Nufone},${ARG1})
exten => _NXXNXXXXXX, 2, Congestion()

[macro-stdexten]
... as in demo ...

==Sip.conf==[user1]
...
context = area555

[user2]
...
context = area666



Thanks,

It should work but you need to do Goto(extensions,666${EXTEN},1)
