[Freeswitch-users] Dialplan expression matching

Well first point I saw the incorrect xml so that can act strangely, usually
you can't even reloadxml correctly.

Next thing is that ^0[1-9]{9}$  shouldn't pass 0930000000, since it is
expecting 1-9 digits after 0, so 0931111111 can pass it. You should be able
to test it here https://regex101.com/ for pcre.

Also make sure you have all xml tags properlly closed, and try not to use
nested conditions, I saw some emails about that not working as expected.
