I'm looking for a small formfactor mobo for an install that needs to handle 25 phone sets (no transcoding). I found a new dual atom 1.66GHz mobo - anyone know what kinds of call volume that will handle? MD

[asterisk-users] Dual Atom mobo - call capacity
Based on comments from Ward Mundy during a recent VUC call I'd expect even a single CPU Atom system to handle that many phones in an office application. Perhaps there may be merit in dual CPU in more of a call center application. http://www.voipusersconference.org/2010/nerd-vittles-incredible-pbx/ Michael Graves mgraves mstvp.com o(713) 861-4005 c(713) 201-1262 sip:mjgraves at mstvp.onsip.com skype mjgraves> -------- Original Message -------- > Subject: [asterisk-users] Dual Atom mobo - call capacity > From: Michelle Dupuis <mdupuis at ocg.ca> > Date: Thu, June 10, 2010 7:19 pm > To: Asterisk Users List <asterisk-users at lists.digium.com> > > >
I don't know how it calculates it, but FreePBX shows a bar for "total calls" that looks like it maxes out at six. We haven't hit that on any installs of this device yet, but that seems pretty low for sure. I know with four calls in progress, all VoIP, transcoding G711u to G.729, the load of the machine is still around .3 . j On Thu, 10 Jun 2010, Michelle Dupuis wrote:> I'm looking for a small formfactor mobo for an install that needs to > handle 25 phone sets (no transcoding).

I benchamrked a 500MHz VIA Geode processor to 85 calls without transcoding. A 1.6GHz Atom can handle 100's. (I use fanless Atom processors in my hosted servers. They're handling 100's of calls.)

I use the single core Atom 230 CPUs for systems of this size. Something to bear in mind is how the system will be used, max concurrent calls isn't really that great a performance factor, call arrival rates are more relevant, the CPU time is spent setting up and tearing down calls. Simply having calls in progress with no transcoding uses a tiny amount of CPU in comparison to the work involved setting up and routing a new call. cheers, Paul.
