=head1 NAME

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

=head1 SYNOPSIS

    use Regexp::Common qw /URI/;

    while (<>) {
        /$RE{URI}{tel}/       and  print "Contains a telephone URI.\n";
    }

=head1 DESCRIPTION

=head2 $RE{URI}{tel}

Returns a pattern that matches I<tel> URIs, as defined by RFC 2806.
Under C<{-keep}>, the following are returned:

=over 4

=item $1

The complete URI.

=item $2

The scheme.

=item $3

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

=back

=head2 C<$RE{URI}{tel}{nofuture}>

As above (including what's returned by C<{-keep}>), with the exception
that I<future extensions> are not allowed. Without allowing 
those I<future extensions>, 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 I<future extension>.
