Let me add that the vast majority of CGs that I've known are at a loss when it comes to VOIP. I They know how to plug it in, but making it work is a different story. Telecom was the unwanted orphan of IT - not glamorous enough, and quite arcane, talking about data telecom now. Voip requires a whole other skill set. I think CGs and telephone people are positioned an equal distance away from that skill set.
Seems like a lot of people here want to let CGs get there first.
