And Lastly……Stealing Minutes
• Phreakers– Phreakers break into gateways to steal minutes– 200M mins/month stolen worth an estimated
$26M/month*– Transport networks now moving to private
connectivity to avoid Phreakers

Current State of Play
• All the afore mentioned problems have either been solved or are close to being solved by session boarder controllers
– Also addressed in IMS
• Service providers are implementing or have implemented security systems
• Businesses building their own VoIP networks will have to be extremely careful about implementation
