Doing that roll back of versioning in Skype causes the channel to freeze completely and doesn't resolve the issue without another flash
You just changed your version in the Skype TX application? Whenever I do that, it locks the channel up. I have 2 - 4000 units and 2 - 100 units that are all doing the same thing.
If I close the Newtek application - it goes back to black outputs
Are you talking about the return to the Skype caller video being black?
We constantly have this issue which is easily resolved by setting the Return to Caller Tab - Video Format from Auto to 1080i and then back to Auto.
