Freepbx, how many users supported?

Hi all.

If i am using Core 2 duo P4 intel system with 2 GB ram, can i support upto 250 users ? I want the following services on freepbx

  1. Auto attendant with several (3-4) options
  2. Trunk to Cisco router, on which SIP trunk from local ITSP will be connected
  3. 250 extensions

I want to get a rough idea, is Freepbx strong enough to handle this much load ?

How many simultaneous calls and what codecs will you be using?

In terms of configuration the system you describe will do fine – but how it’s used.
