I had the same problem with a connection over our local Cable Co., even 
the engineers could not tell me why. I was able to route around it by 
putting in a direct route, anything that went through their gateway 
didn't work as described. Some internet routers and gateways drop rtp, I 
think, expecially systems designed to filter the traffic.
