asterisk users - Mar 2013 - asterisk sizing for play and dtmf detection

Dear all

i'm planning a migration to asterisk for a high volume IVR service
(from 1000 to 1500 concurrent call)

The IVR service is based only on DTMF tones so the features required is

- play feature
- dtmf detection

Asterisk will receive calls via VOIP (SIP with g711 codec)

The IVR service wil be a static service based on Asterisk dialplan
with some prompt (from 0 to 5, play of files in the same codec of the
received call) and some dtmf detections.

How many simultaneous call can i handle per server? each server will have:

4 core 3.0 Ghz
4 GB of RAM

I need an aproximate sizing:

0-100 calls per server ?
100-200 calls per server ?
200-300 calls per server ?
300-400 calls per server?
400-500 calls per server?

Thanks to all in advance

The bigger server I have has 150 max channels during peak hours and has a
max load of 0.5 with 24 cores. When I was using a 4 cores server with the
same number of channels, I get a load of 3 ... so the load x core relation
is valid. I think it will be good to have a load not over 4 for a 4 core
server, so you can have at least 200 active channels on the server. If you
accept more load, then you can get more channels.

If you accept calls on.g711 and static ivr dialplan you should be able to
do around 300-400 concurrent on the box config that you provided.

And If you pay some expert consultant, he may be to fine tune it to be able
to handle 500 concurrent as well.

Which version of asterisk are you planning to use?
Any DB integration layer inside IVR?
