[Asterisk-Users] fallthrough extension.

[Jon Lawrence]

Hi all,
I'm trying to sort out my dial plan.
What I'm wanting is something like the following - a bit simplified but 
hopefully you'll get the idea.
1) match internal extensions: dial them
2) anything else: send out zap

1 is easy :) it's 2 that's giving me problems.
I had hoped that the 'i' extension would act as a catchall extension but it 
seems to only do that from a menu. I've tried matching _. (hoping that * 
would parse the dial plan from top to bottom) but that just took over the 
entire dial plan and everything went out of the dial with the _. match.

I'm sure that there must be a way of doing this, can anyone point me in the 
right direction.

TIA
Jon
