[Asterisk-Users] Re: Compressing a dialplan

[Maron Kristófersson]

By sorting the plan there should definitely be a way to do it, you will 
need some algorithm that takes all the numbers digit by digit ( first go 
through all digits nr. 1 in all possible numbers, then nr. 2...).

However what you're trying to do makes me think if asterisk shouldn't be 
able to pass Early Dial on to the telephone network channels.  What I am 
thinking is that you could define in extensions.conf that you wan't the 
Zap or Capi device to start sending numbers immediately, if the Zap 
device get's a complete number before the dialplan in extensions.conf it 
will decide that the call belongs to it and hooks up with the ringing 
notification to the caller.  However if the number matches an extension 
already defined in the dialplan, it will hook up to that one.

The Zap channel could be made listening by default, or only if the first 
character is a specific character like 0.

This would be a sacrifice of a Zap channel everytime somebody starts 
dialing but I think it's worth it in many cases.

Probably this has been thought of before (or am I forgetting the minor 
detail that ruins the idea?) but I would like to hear what the 
developers have to say about it?
