THanks, this seems to almost get me there... Once I call into the server
and goes to my locals I no longer get Video.

When I call the extension directly I get video no problem.

When I first call the server at my IP address then it routes to my local
I no longer get video.

Any ideas why that might be?

THanks,

Jerry
