Unfortunately the operating carriers will not insure you against dishonest usage and you will be ultimately liable for the cost of them!

Be sure that yours’ has unique or strong codes on everyone’s mailbox. Many PSTN customers have had their VoIP telephone systems checked by their service technicians when they have a reason to visit such as a reported fault.
