Hi Joel, and thank you for your response. Actually, I use one IP but two different ports. I have not yet figured out why some Providers need two listening ports but other need one. As I mentioned, the ones that need one port will only have one way Media if two ports are used. This is extremely Strang!
Yes, I am trying to use RTPEngine but have not been successful. I have earlier posts (this week) which explains the problems I am having with RTPEngine.
