How does the service provider differentiate between data and VoIP as data?
For our mobile devices in trucks, we use GSM/GPRS communication. Our customers are paying for a certain data amount -- depending on the service package to which they subscribe. We use a modem in our device, which can do both data and voice. But as I understand it, with VoIP, everything becomes data. So, is it cheaper for the user if they use VoIP? How will operators handle this from a business model perspective? Will they expand the data amount packages or will they need to differentiate between 'regular' data and VoIP data? And a technical question: how much VoIP data am I consuming if I have a one minute voice conversation? Continue Reading

Calling network management vendors: It's time to get on board with VoIP
Despite the hype, full-scale VoIP deployments are hard to find. According to our research at Yankee Group, over 80% of U.S. enterprises have VoIP deployed somewhere in their organization in some shape or form. This includes departmental trials and development environments. These kinds of statistics combined with a frenzy of media and vendor hype would leave one with the impression that we're right around the corner from ubiquitous VoIP and if you haven't deployed it yet, you're a luddite and you're putting your business at risk. However, digging a little deeper into our research we discover that a mere 6% of U.S. enterprises have VoIP running throughout their organization and caution is more the norm than the exception Continue Reading
