asterisk users - Aug 2005 - Minimum CPU required for 60 calls

I am interested in how much CPU and RAM asterisk requires for call handling.

1. What is the minimum CPU required for asterisk to manage 60 concurrent calls
without transcoding.

2. Handle calls on a 75% no transcoding, 25% transcoding


3. How many calls can it connect per second ie from one VoIP -> VoIP?

All the above refer to a VoIP setting.

4. Is there a difference between bridging and transferring?

I *really* dislike these kinds of questions.

Grab some hardware and try it.  It is the *ONLY* way you will know for sure.  
Grab a single processor Pentium 4 or Celeron system and do some testing. 
I'm
sure you have one sitting around somewhere you can use for a test, even if 
you have to put a different hard drive in it for the test.

Typically speaking, if you have to ask these kinds of questions you are 
NOWHERE near the level of competence in Asterisk to try and skimp and save on 
the hardware.  That is not meant as an insult, either.  Get it working, THEN 
start looking to pinch the pennies.  You will only be disappointed otherwise.

Now Mr Andrew Kohlsmith, can I call you Andy? Thanks for your answer to my
earlier query, but answering this one in this manner WILL NOT GET YOU INVITED
TO CHRISTMAS DINNER !!! (to paraphrase one Sergeant Murtagh)

I understand that some geek types don't have much time for non-techies who
they
feel don't want to do their diligence, but non techies have one trait - if
they
don't know something they ASK, they don't try to work out everything for
themselves, unlike of the wheel reinventing that seems to dog the geek world.
This can be a VIRTUE. Concentrating on one's unique added value in any area
of
endeavour matters.

I have installed Asterisk but my expertise in it does not extend to simulating
the demands of 60 calls, as I don't have the facilities to put 60 real calls
through them, and it could take me days if not weeks to get to that stage. Does
it hurt to inquire? Would you be happier if I asked for a way to simulate 60
calls on a box? If you can point me the way I would be happy with that.

You might be annoyed at the noise level, but this is a users mailing list, not
an advanced users mailing list.

The nice man Adam posted this link
http://www.voip-info.org/tiki-index.php?page=Asterisk+setup+medium+office+100,
which led me to find out a lot more and so did a few others.

Please Andrew, the mailing lists are not just a place to vent your pet peeves,
they are also a place where you can be nice to others - does one Victor Meldrew
spring to mind (hopefully you are not that old) :-).

If you have a critical comment to make, by all means do so, but try to go some
way in helping with the question.

I also have no intention to skimp on the pennies.

Yours Obelix.

PS.  You will get invited to dinner now.

That was long, wasn't it :-)
