[Asterisk-Users] Re: Pattern matching problem

[Eric "ManxPower" Wieling]

You are correct.  _NXXXXXX matches 6137451.  Once Asterisk sees 7 
digits, the first digit not being a 1 or 0, and since it sees that no 
other patterns can match, it immediately stops listening for DTMF and 
starts dialing.

If you don't like that then add:

exten => _NXXNXXXXXX,1,Goto(i,1)

And that will match your 10 digits.  But of course, since Asterisk now 
has pattern matches for both 7 digit and 10 digit numbers, when you dial 
a 7 digit number Asterisk will wait for DigitTimeout before deciding 
that you wanted to dial 7 digits and not 10 digits.

Or you could add exten => _NXXXXXX.,1,Goto(i,1)  Which will match 8 or 
more digits.
