:If you read my original post I referred to using this in corporate networks. Meaning a network for a company that subscribes to an ISP and pays for a fixed bandwidth.
Usually, they are charged an arm and leg by the ISP, and therefore don't like the idea of their employees getting a free phone ride on the corporate internet access.
You think phone calls are free? The phone company charges our company for every phone call, even local ones. I suspect that moving our phone traffic over to VoIP would lower our total costs.
