asterisk users - Feb 2007 - requesting real world meetme capacity numbers

Hi All,

I'm very interested in real world experience of double digit number of
users sustaining good quality audio in a single meetme conference.

Personally, I have seen 23 users in one conf room, all coming in SIP,
ULAW.  Server is 3.2GHz proc, 1Gig RAM, 1-2 % proc utilization under
23 user load, perfect audio.

I'm working on a conf bridge for 150+ users, could use some advice, if
anyone has accomplished such a feat or has any ideas on how.

Thanks.

Above a certain number, background noise destroys the conference.

Anyone remember what the number is?

I'd be interested in your findings.
I'm leaning towards app_conference - you should evaluate it at the  
very least.

With those sorts of numbers you will have to mute the vast majority  
of users
and have them press a button before speaking otherwise the audio will
vanish under the weight of 150 people breathing :-(
