Using your 200mb quota + 2GB extra at $150 a gig doing VoIP - Priceless"
As far as I know VoIP uses very little bandwidth an uncompressed VoIP stream is 128Kbps and modern schemes like G.729 can be as low as 12Kbps. So to use 2GB for VoIP you would have to talk for approximately 48 hours.
This is not counting silence suppression (i.e. only one of the two people in the conversation are generally talking at any one time so the other node does not sent packets) This means that only about 40-50% of the maximum bandwidth is used on average. So you can double the 48 hours number.
