NAME

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

SYNOPSIS

use Regexp::Common qw /URI/;

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

DESCRIPTION

$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 future extensions are not allowed. Without allowing those 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 future extension.
