I am making good progress, however I always seem to have NAT issues with nathelper, so I am trying to use MediaProxy. I have it installed, and the calls are showing up on the Media Sessions page, but they always show as "Status: inactive" and never show any actual traffic. Also, the client that is behind NAT (or not) can not pass any voice traffic in or out. If I run the rtpgenerator.py it shows the test rtp with traffic flowing. Any ideas? Thanks, Doug
