Tuesday, April 19, 2011 SIP & H.323 – How Does it Work?
So, have you seen the rumblings of using the SIP standard instead of H.323 in schools?
I ran into this during Read Around the Planet.
Some schools with TANDBERG installations on the east coast gave out their address to dial as an email address! This caused some confusion and trouble for Read Around the Planet this year. They didn’t seem to know that most schools with H.323 couldn’t dial it or didn’t know how to.
I don’t really understand all the technology – but I see the effect on educators trying to connect “advanced videoconferencing” with other schools who have “advanced videoconferencing” (i.e. Polycom, Lifesize, Cisco-TANDBERG, etc.).
These are the questions that are raised in my brain. What about for you?
- How does an old Viewstation connect to SIP?
- What has to be in place for H.323 to connect to SIP?
- Why is it that the school with the new TANDBERG HD installation couldn’t dial an IP address with the dial protocol on auto? They had to select H.323. That’s not very educator/user friendly. Most educators don’t know the difference between H.323 and SIP. I barely understand it!
- Why is it that this school with new TANDBERG HD equipment couldn’t call older Polycom systems during Read Around the Planet? I think it might have been Viewstations they were trying to dial. Shouldn’t H.323 be able to call any H.323?
- If a content provider buys a new system that uses SIP – who will advise them on how to connect to schools that can only dial out?
- Is Cisco-TANDBERG really pushing SIP now?
I am trying to understand the ramifications of this for programs such as Read Around the Planet, collaborations between schools through CAPspace, connections between schools and content providers around the world, etc.
What do you think? Any ideas? Please comment!
