=head1 NAME

FS::svc_phone - Object methods for svc_phone records

=head1 SYNOPSIS

  use FS::svc_phone;

  $record = new FS::svc_phone \%hash;
  $record = new FS::svc_phone { 'column' => 'value' };

  $error = $record->insert;

  $error = $new_record->replace($old_record);

  $error = $record->delete;

  $error = $record->check;

  $error = $record->suspend;

  $error = $record->unsuspend;

  $error = $record->cancel;

=head1 DESCRIPTION

An FS::svc_phone object represents a phone number.  FS::svc_phone inherits
from FS::Record.  The following fields are currently supported:

=over 4

=item svcnum

primary key

=item countrycode

=item phonenum

=item sip_password

=item pin

Voicemail PIN

=item phone_name

=back

=head1 METHODS

=over 4

=item new HASHREF

Creates a new phone number.  To add the number to the database, see L<"insert">.

Note that this stores the hash reference, not a distinct copy of the hash it
points to.  You can ask the object for a copy with the I<hash> method.

    },

sub table_dupcheck_fields { ( 'countrycode', 'phonenum' ); }

=item search_sql STRING

Class method which returns an SQL fragment to search for the given string.

=cut

sub search_sql {
  my( $class, $string ) = @_;
  $class->search_sql_field('phonenum', $string );
}

=item label

Returns the phone number.

=cut

sub label {
  my $self = shift;
  my $phonenum = $self->phonenum; #XXX format it better
  my $label = $phonenum;
  $label .= ' ('.$self->phone_name.')' if $self->phone_name;
  $label;
}

=item insert

Adds this record to the database.  If there is an error, returns the error,
otherwise returns false.

=cut

# the insert method can be inherited from FS::Record

=item delete

Delete this record from the database.

=cut

# the delete method can be inherited from FS::Record

=item replace OLD_RECORD

Replaces the OLD_RECORD with this one in the database.  If there is an error,
returns the error, otherwise returns false.

=cut

# the replace method can be inherited from FS::Record

=item suspend

Called by the suspend method of FS::cust_pkg (see L<FS::cust_pkg>).

=item unsuspend

Called by the unsuspend method of FS::cust_pkg (see L<FS::cust_pkg>).

=item cancel

Called by the cancel method of FS::cust_pkg (see L<FS::cust_pkg>).

=item check

Checks all fields to make sure this is a valid phone number.  If there is
an error, returns the error, otherwise returns false.  Called by the insert
and replace methods.

=cut

# the check method should currently be supplied - FS::Record contains some
# data checking routines
