             Summary: Dialplan pattern matching error
                 Key: ASTERISK-23805
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-23805
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/Dial
    Affects Versions: 11.9.0, 11.4.0
         Environment: CentOS 6.5
            Reporter: Andres Mazzocchi
            Severity: Minor


There's a little flaw in the pattern matching algorythm. This pattern is pretty straighforward:

exten => _9XZ.,1,Answer()

It means one should be able to dial 9(0-9)(1-9). numbers, unlimited length.

However, if the dialed number begins with 920., Asterisk returns the following error:

---
Call from '2801' to extension '920256666' rejected because extension not found in context 'xxxxxxxx'.
---

A simple workaround is to add an additional entry tailored for these specific numbers:

exten => _920.,1,Answer()

Furthermore, the pattern recognizes correctly numbers 921 to 929. The only one that is not recognized is 920.

I've discovered this while using Asterisk 11.4.0, then I upgraded to 11.9.0 and the error is still present. I don't know about the versions in between.
