=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

=item pbxsvc

Optional svcnum from svc_pbx

=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.

# the new method can be inherited from FS::Record, if a table method is defined

Returns a set of Call Detail Records (see L<FS::cdr>) associated with this

Accepts the following options:

=item status => "" (or "done"): Return only CDRs with that processing status.

on inbound processing status.

=item default_prefix => "XXX": Also accept the phone number of the service prepended 
with the chosen prefix.
