I tested by calling Polycom and they connected into the our cameras. I 
also tested our polycom by connecting to their testing units with no 
problems.

If I recall correctly I had to open a  couple of specific ports, and 
then a range of ports. I also am assuming you have opened the correct 
firewall rules? It did take me about two weeks because of some stupid 
little mistake, but it did work.

I am in the middle of moving next week and getting my file server back 
up and running. I will try to find a copy of the working config file and 
let you see what I did. Since it was a while ago I can't really remember 
exactly what I did. It would also be helpful to know which equipment you 
are using and also get a copy of the instructions for them. You can mail 
me off list.
