Terry, thanks for compiling on this important state information for H-323.
For those of us who are nit-picking could you give us a definition for the elements in the table?
x o t new(???) n/a (blank), etc.
I'm not really sure what they mean. The labels at the top of the table, why they are there also need some definition, although I think I know what they mean. A paragraph on the scope of the table would also clarify, for example, are conference calls included?
Also, if you could take us thru one scenario in the table that has different elements in it, that would be helpful. I want to make sure I have the right interpretation of the table before we talk about it on Thursday at the teleconference.
Thanks.

I have been working on collecting the call state information present in various H.323 network elements. The goal is to: 1. see what data is present 2. suggest what data must be re-established if a new element takes over (or an element recovers but has lost call state data) in order to allow the call to continue at various specified levels of recovery: - call can continue but billing data lost - call can continue with full billing data - etc.
I have certainly not completed this study, but have collected a fairly complete set of call state data items and put them into a table indicating which element(s) they reside in. The plan is to choose a notation to indicate how vital each element is for various levels of recovery and which other element has the data that can be used to restore it in the new element.
I will share this much at this time and perhaps we can begin a discussion about - completeness (what I have missed) - presentation (is there another format that could make the information more understandable)
I am attaching it as a word document.
