Caseydoug, your previous post on page 3 seems appropriate.

Carve out as much of a port range for Voipo's ATA that you can and hopefully this will not interfere with any other devices that maybe in this port range. I'd estimate the majority of people out there (95% or more) do not have other devices that conflict with UDP 5000-65000. They'll just have to experiment and see what works.......
