Seems like this could be fun/golf

I am using Active Perl 5.8.8. and Perl Dev Kit 7.0.
I'm writing some code that standardizes the format of phone numbers in a
database because users have entered them in every way imaginable.
Anyway, some of the phone numbers look like this:
800-69-VORTEX
...where the user has entered alpha characters instead of numbers. My
first thought was to use a hash to do the translation, like this:
%alpha2num =
(
'A' => '2',
'B' => '2',
'C' => '2',
'D' => '3',
.
.
.
...but since the rest of the routine uses only regular expressions, I
thought that it would be nice if this type of translation could be
accomplished with a regex.
I have not been able to think of a way, but I thought I would put it to
the list to see if anyone else has done this before.
