Re: [Asterisk-Users] Conference bridge dimensioning

I am currently running stock MeetMe configs at multiple locations on single P4 hardware (512M and 2G, depending on which location).  I've seen no problems (no technical problems) up to and over 30 attendees, all coming in via H.323 (chan_h323), using g.711u (no transcoding).  Word of warning- above 10 people, a single misconfigured softphone attendee can create chaos (our fave is the guy who uses a softphone on a laptop without a headset, and doesn't mute, combined with the guy who is listening in on his cell phone from a train)- the noise level can become chaotic if you do not set up the meetme in 'broadcast' mode (1-2 presenters, rest listening in).  Based on load averages (at 25 people, on a single P4 with 2G ram and nothing else going on on the box, we see about a 0.5 load average), there's no reason why it wouldn't support 50 or 60 attendees before seeing problems.

Hi Jordan,

  We are planning on building the same thing. We are still waiting for the hardware. We are using a Dell PE 2850 3GHz with 2G of RAM and a TE210P.

  I asked Digium support if this can suupport 50 users in one conference and the tech support guy said yes.

  Here's also a response from this list

  Let's share our experiences.

  Goodluck.

        st1\:*{behavior:url(#default#ieooui) }                We are using an Asterisk box to do conferencing right now. I have had about sixteen active lines in conference and the quality was acceptable. We now have a need for 50 people to conference at one time. Does anyone have enough experience doing this to give me some pointers. Will it even be reasonable to try this? Is the mixing done on the the hardware, I plan on using a quad span t-1 card from Digium? The server is a fedora box with a dual core xeon at 2.0 Ghz and 2 gigs of Ram. Is there a rule of thumb to go by as far as conferencing resources?
