>P.S. How many folks out there have phones (hard or soft) from which >they can place calls to other random SIP endpoints? (I do, but also >realize I'm in a minority.) Probably enough of us. I agree that SIP conferencing doesn't work perfectly, but POTS conferencing, even rather high priced POTS conferencing, is often pretty bad, particularly when people are on cell phones or calls over other noisy or slow links. It's certainly worth a few experiments to see if a $0 conference is really worse than a $1000 conference.
