Recently, I was reading the release notes for the latest version of the TANDBERG MPS MCU software after we upgraded our bridge. I noticed a section about H.239 that indicated that passing the H.239 streams between different types of bridges – the Polycom MGC, Codian, TANDBERG, still doesn’t work consistently. There are known issues.
I’ve written already about other scenarios I’ve seen where H.239 doesn’t work. The MCUs talking to each other seems to be another area of potential conflict.
So if you have a unit that does H.239, you should always have a back up plan for showing your visuals. I’m thinking specifically of MysteryQuest where we connect a lot of different types of endpoints in the same conference, and even Read Around the Planet.
