Shidan: WOW! " As far as what's needed to make * work effectively, a Sangoma card on a P4 can handle 200 calls/second, with no transcoding".
That's amazing! 200 calls per second.... on the Sangoma. With regards to CPU usage and dual proc. capabilities... granted and ALL agreed with what you are saying with regards to quality of sound & services etc. But on a small office scale... handling 10 - 20 calls ... do you really need all that horse power? Leaving the factor of TCO, does one really need a Ferrari to go from Toronto to Mississauga - where a Honda 4 cyl. would be more than enough? Realistically speaking... within the confined office of 20 people, you can obviously configure your IP phones to all negotiate at the same codecs. Hence no transcoding involved... except perhaps the added options for call monitoring, conference calls & voice mails. Please don't get me wrong... I'm ALL for Dual Proc., and support it 100%... if the money is coming from someone else's pocket... and if cost is not a factor... why not! But even in a small office of 20 people where all 20 people are on the phone at the same given time... is a dual processor really all that necessary from a technical perspective? Would appreciate your input.

For any * purpose given the same setup a dual processor will always work better, festival, the tcp stack, agi forking, ........... ,the list goes on and on, can take advantage of the extra cpu to do lots of good work. Actually even Asterisk works MUCH better on a dual processor. As far as codecs go its threaded just fine. The only problems are its main thread which do all the cleanup, and the actual transport stacks, which are being worked on, at least for IAX as the posting. With more CPUs, in many cases, the actually quality of the call will increase, not just the number of calls you can handle. Echo can. and trancoding (voice not protocols) are inherently costly, and software is still not the best place for them, thats why good cards still matter (thats not really why good cards matter in * because neither Digiums or Sangomas do this yet and for the cards that do, none of those things have been interfaced with zaptel yet). But good cards still do matter with *!! As far as whats needed to make * work effectively, a sangoma card on a P4 can handle 200 calls/second, with no transcoding.
