[VoIP] Asterisk Programming Technique

[Lee Spenadel]

So it looks like I'm back to my original *x dialing plan for connection to
other services.  Hey, life could be worse. Thanks for your help guys.

Yup, my way won't work if you have overlapping numbers of the same  
length.  You *must* distinguish them somehow.

This is why I use the 200 prefix for CNET.  This also works the other  
way (from the step switch back to the network.)  By dialing 1+200+ the  
CNET number, I can send a call out the network correctly for CNET and   
1+ some real NANP number will go out to the real PSTN.

In Minneapolis, MN we can (normally) dial

7 digits for a phone number in your own NPA OR
10 digits for a phone number in your own NPA
10 digits for a phone number outside your NPA (but still local)

1+10 digits for toll calls.

Obviously, if I want to call my neighbor using 7 digit dialing, who  
might have the same number as a CNET switch, I have to distinguish it  
somehow, and I chose to prefix an unused NPA for CNET.

An unused *xx code might be a good way to go for routing calls via FWD  
or other services.  Maybe *FWD  :)
