Issues with carrier-based IPV Many thanks to the readers who replied to our newsletter last week about IP Video (IPV) offered as a managed service within a carrier's IP-VPN portfolio.

IPV over an IP-VPN Following our recent newsletter focus on IP Video, we heard from one of our readers with some excellent questions about IPV over an IP-VPN. He asked, "What would you say were the challenges inherent in adding video to an IP VPN that is already set up for data and voice? Some ISPs offer VoIP convergence with data over an IP VPN but not many offer video too. I would have thought that many industries would welcome the addition of video conferencing over their VPN as a way of saving time and money going to meetings. Is there a reason why this is not being offered as an add-on service?"
