Is anyone other than me have a weird year with video protocols? It used to be that you just had to think about… is this call H.323 (IP) or H.320 (ISDN)? and connect accordingly. Now sometimes two video protocols (H.261, 263, 264) get in a call and have a fight with each other!
This year so far I’ve several strange things happening with calls with both Polycom and Tandberg units that can do H.261, H.263 and/or H.264. This morning I was troubleshooting a call with Andrea Israeli, NY and a ClicktoMeet site for Read Across America. Andrea and I have identical Polycom VSX7000’s on the same software rev and the ClicktoMeet site could call me but they couldn’t call her. Very strange. On a hunch, I suggested forcing the call down to H.261. Voila! It worked.
I feel like I’ve been sucked into 261/263/264 la la land. It’s a land where you never know if your calls will work. But it seems that forcing the call down to H.261 makes it work. Why is that???
I love the idea of H.264 working on low bandwidth sites with better quality. Another of my Read Across America connections is with a class in Alberta who called us at 128K. The quality was beautiful! Polycom People Plus Content came across great as well. I’d really like to see this work on a consistent basis. I guess we just have to weather this bump as the vendors work it out.
Crossing my fingers for 32 mostly Read Across America connections this week….
