My advice is to forget about "dial 0 to get to the outside line"
mentality when using Asterisk.  However, you can easily implement "dial
0 to get to the outside line" in Asterisk but the problem is once 0 is
dialled, it is totally outside Asterisk's control.
For example, you cannot use Asterisk to bar some numbers which you don't
want users to call.

Because of the varied nature of the telephone numbers that people may
dial, I think it makes sense to get the users to press dial or send
after they have enter their number.
