Does anyone know where i can find out how powerful a machine has to be to handle a certain amount of call volume? Eg, 2Ghz is enough processing power to maintain 100 calls at a time. 4Ghz is engouh to process 250 calls etc etc. Thanks Dan -------------- next part -------------- An HTML attachment was scrubbed...

Messuring processor power using megahertz is like mesurring speed of vehicles by messuring horsepower. You'll find big trucks with more horse-power that a F1 car, yet, the big truck is slower. Frecuency of procesor only guarantees the same change in power in the same branch of processors, like comparing two P4, or two Athlon XP, but if you start comparing AMD vs Intel, that is no longer valid, and let me drop a different processor like a Spark, PowerPC, etc, and the comparation is very, very useless. We should start comparing procesors with better mesurring units, like flop (floating point operations per second). Even then, when messuring a system for something like handling calls, bus speed may be important, as well as network speed (don't neglect those other aspects). If you do transcoding of all the calls, then you'll need a lot of processor ;) -- Jos? Pablo Ezequiel Fern?ndez

How are calls being terminated? Are they being trunked? What codecs do you plan on running? Will the server be transcoding? MOH? Etc. There's no clear answer, really.
