At a few shows, including the latest ITEXPO, the 3 big cablecos - TWC, Comcast and Charter - share a booth. One message, 3 supposed separate companies. Now they are doing training together. How? Are the systems, processes and products the same? Kind of.
TWC doesn't have a Hosted PBX offering yet. And TWC will likely never have one, since it is up for sale and about to be parceled out between Comcst and Charter.
You can't call it collusion because they don't do it in secret. If the ILECs did this (and who knows they might at USTA meetings), the FCC would step in.
