  Serge,

    How are you going to be building this server?  I am not going to claim
to be any sort of expert on
  sizing, but I do have some experience as an IVR designer/developer.

  In one of your previous posts you mention E1 cards.  In order to get 300
msgs at once you would need to
  be running 10 E1s, is this reasonable?
  How many questions are there in your survey, how long is an average call
going to take?
  say you have 5 questions, and a complete call will take approx 2 minutes
  allow for call-setup and call-breakdown - 15 sec
  should allow for 26calls per hour per channel @ 30 channels = 780 calls
hour using just 1 E1
  In this case you would only have, at maximum, 30 prompts playing at any
one time.  From what I have seen in this mailing
  list there are servers out there doing a lot more than that (but I do not
know what the hardware is).

  I have built systems running at that level of traffic using the Contarra
IVR platform and running on a P4-1.6GHz with 512MB on a dialogic card.
  Surely an * box with a decent CPU & Memory can handle it no problem.

  Now that I have gone stated all this for the world to criticize, please
let me know if I have made any critical mistakes/assumptions.

  Shawn
  P.S Contarra & Envox I know, Asterisk I am learning.
