Otherwise, someone else always is the carrier to your ISP's transport.

For example, Comcast cable modem with Vonage phone service. With T-Mobile's UMA service, your ISP will be the transport, but T-Mobile will still be the carrier (your usage takes away from your monthly minutes).
I understand the comcast/vonage scenario, because that's what I have, but it still requires a Vonage phone adapter installed to be able to make calls through the cable internet service. How exactly do you make phone calls on your wifi bb using tmobile minutes on a cable internet connection?
