I hate to say it, but jumpping off into a 100 channel PBX is not the way to go with Asterisk. Build a 1x1 PBX first on an old Pentium 500. get this to work then try adding SIP phones then add some other features. After you've spent some time you will not need to ask the above. In fact I'd say if you need to ask
Guys,
Thanks for all the helpful advice, but I think we're getting off topic. I have specific engineering requirements I have to meet. I can not change my problem space. I need a 30 user G.729 (not 100's) plus custom apps, single box solution. No buts, and I need to make it as cheap as possible. This is for Thailand...you can spend $100 on an overpowered computer or you can feed your family for a month. (No joke!) Price matters....alot. I don't want it to scale. My problem space is fixed. I don't need to build a general purpose PBX.
What I really want to know is, what are the constraints of the G.729 codec? Does anyone have any real world experience implementing this, and is the resource utilization a result of mathematical floating point calculations, or a result of branches and sequential processing instructions?
Can anyone give me some solid advice here on how resources are being used?
What you've taught me so far is:
A) you believe that MP or HT will help the performance. Problem is, these
are expensive solutions. Can you quantify this answer at all? How much
will it help, and would it help more than additional floating point performance?
B) The G.729 codec is linked to the hardware, so I can't even experiment without having to pay for it each time.
Question...is there anyway to transfer the G.729 licenses from one system to another when I don't want them anymore? I need to answer this questions, and paying $300 everytime I need to check out a new architecture (and worse than that waiting for 24 hours) simply isn't practical.
Does anyone have contact info for an engineer at Voiceage who can help answer my questions? Is there a multi channel developers license available that would transfer across different hardware architectures?
Thanks for your feedback,
Chris Ziomkowski
