I also understand your stand here Kevin - there is no way you can restrict the software running on a server out in the wild, and no way to make sure the software they are running will not conflict in any way.
But a single port E1 card with hardware echo cancellation....possible? PaulH On Wed, 2007-11-28 at 17:22 -0600, Kevin P.
