Regexp::Common::URI::tel -- Returns a pattern for telephone URIs.

       Bound to be plenty.

$RE{URI}{tel}
       Returns a pattern that matches tel URIs, as defined by RFC 2806.  Under "{-keep}", the following are
       returned:

       $1  The complete URI.

       $2  The scheme.

       $3  The  phone  number,  including  any  possible  add-ons  like  ISDN subaddress, a post dial part, area
           specifier, service provider, etc.

   "$RE{URI}{tel}{nofuture}"
       As above (including what's returned by "{-keep}"), with the exception  that  futureextensions  are  not
       allowed.  Without  allowing those futureextensions, it becomes much easier to check a URI if the correct
       syntax for post dial, service provider, phone context, etc has been used  -  otherwise  the  regex  could
       always classify them as a futureextension.
