asterisk users - Oct 2008 - Dimensioning a telephony system based on openser!

Hi,

  I've sucessfully completed an Openser 1.3.2 + Mediaproxy 1.9.1 + Asterisk
1.4 + CDRTool with freeradius telephony system.
  Asterisk is used only for voice mail and redirectioning calls.
  Every calls should pass through mediaproxy so that i can account them.
  The goal was to create a simple prototype of what could be a VoIP
provider.
  Now i need to dimensioning this system to work with this requisites:

       - 10000 users;
       - 100 VoIP to VoIP calls simultaneously capacity;
       - 30 VoIP to PSTN calls simultaneously capacity;

  Can anyone point me some ideas of how can i design such a system (how many
servers, how to distribute the services among them, etc.).
  I have this prototype mounted with VMWare, so i think that even making
tests with sipp aren't going to be reliable.
  Thanks in advance,

                 Nuno

You can do accounting without handling media.

Without mediaproxy? Only based on SIP messages?

Yes.  There are some liabilities with that in that the signaling 
messages may be incomplete (i.e. you may miss a BYE) and this is the 
usual reason given for doing media proxying for more accurate accounting.

But the latency, bandwidth consumption, and increased complexity and 
cost associated with doing it on a large scale does not justify it, in 
my opinion.  SIP-only accounting is "good enough" most of the time.

"SIP-only accounting is "good enough" most of the time."
Does not work in production environment. Specially when you are charging per
second or per minute.
Works only if some one is offering unmetered only service or just doing it
for fun. If it metered service like calling cards, termination or metered
DID etc, then this can be really bad.
My 2 cents.
