[Freeswitch-users] Bracketing or not bracketing

[Steven Ayre]

These will match identically.

The only difference will be the second will set $1 to 123456789, the first
will not.

Brackets are only needed if you either want to capture part of the match
into $1 etc, or you want to match against multiple possibilities
(this|orthis).
