Simultaneous calls

can anybody tell me how many simultaneous outbound PSTN calls can be handled via asterisk??

  1. depends on bandwidth
  2. depends on codec used
  3. depends on hardware
  4. depends on number of trunks

How many do you want it to handle?

what maybe the hardware requirements for handling a 10000 simultaneous calls and required setup??
