Does VoIP use gobble up lots of data, if you're being tracked by our ISP or Comcast?

Some who read the lower post about Comcast now metering one's data use wondered if using Comcast Voice, or any other home VoIP product, would really eat up large gobs of data.Walt Neary, who works for Comcast on the west side, said it won't.

Here are Walt's comments shipped by e-mail:The streaming data in VoIP calls just doesn't use that much bandwidth on a relative scale. We're quite serious that the 250(GB limit) is only going to affect a very, very small group of people.

The folks I talked with are leery about providing numbers publicly because Vonage or Skype might have slightly different numbers, or you might talk with someone who is/says they are a VoIP expert and have different numbers.
