Was there a particular reason why you were trying to use \[the "new" pattern matching engine\]?

No, there was not. I must've toggled it years ago for fun; new is better right?

When I configured that machine, I didn't correlate the \+31NUMBER bug with the new pattern matching engine. I thought it was some kind of bug related to the {{+}} sign at the time. Now, my asterisklint told me remove the {{_}}'s, at which point the bug reappeared and I decided to figure out what was wrong.

Long story short: I don't mind if the new engine is dropped. I don't use it on purpose.

> When executing dialplan with {{extenpatternmatchnew=yes}} set, some patterns do not match the same as they did with the old dialplan engine.  The example that I came across:
> {noformat}
> exten => 7,1,goto(100,1)
> exten => 100,1,noop(Dialplan chose correctly)
> exten => _1X[0-5],1,noop(Dialplan chose WRONG)
> {noformat}
> Under the old dialplan engine, the 100 extension would be chosen (correctly since it is more specific).  Under the new engine, {{_1X\[0-5]}} is chosen instead.  This is not a major issue since the new engine is disabled by default.
