Hrm... Isn't a VoIP call realtively low bandwidth? I haven't studied this, but Vonage's site seems to imply that the maximum data rate is 90Kbps

typically see speeds greater than this from my web browser... Are they saying that anything that might consume over 100Kbps isn't going to be allowed?

it's not about bandwidth, it's about pps. namely, radios don't very much like a lot of pps ;]

Using Vonage and a call to my cell phone, an unscientific, but reasonably accurate estimate: I left a voice mail on my cell "my voice is my passport" and dropped the call from the Vonage side. Call duration was 81s. Average speed was 80pps. The avg packet size was 200b. The call was "BYE" at 60 seconds, but there was a REGISTER at 76s so I included that as the call teardown marker and in the averaging. I didn't think being liberal would hurt. -M<
