    Anyone have any experience with this? Our set up is fairly simple; we have
    4 locations in 3 states connected via VPN over dsl lines of various speeds
    (1.5meg, 768, 768, 512 all asynchronous). VPN works great, but when I've
    experimented with netmeeting there is a 3 or 4 second lag in the voice and
    the video is pretty choppy. Do I need frame connections to get the QOS
    that is needed or is it possible to make our set up work.

    Thanks

    Once your data enters the VPN the QOS gets eaten! Sorry, but I think you
    cannot combine the two because your network can no longer give priority
    to the VoIP when needed.

    That's what I figured but had to ask anyway.

    Thanks

    Give priority to the VPN perhaps?
