I have set up a conference with four people on a very low-end box. The voice quality was very good. All four were connected using VoIP. Three were using IAX2 clients, and one was using a SIP hardphone. I suspect the system could have easily scaled much further -- the CPU and memory usage were fairly low. I've pushed a low-end system far enough to encounter problems. I set up what I thought was a prototype system on a box salvaged from the junkheap, and it immediately became so popular it got overloaded. * 1, New Jersey: P-II 350, 192 MB RAM, RedHat 8.0, * 1.0 stable * 2, Jamaica: P-III 800, 256 MB RAM, RedHat 8.0, * 1.0 stable 7 party conference on * 1 in New Jersey. 3 extensions on * 2 via IAX trunk to * 1 (no jitter buffer). Four calls on * 1: 1 IAX to VoicePulse, 1 local SIP, 2 remote SIP on Xten softphones in Vermont and UK. All calls are GSM (including IAX trunk) except for 1 local SIP user who is ulaw. 7 users sounds OK *if* the network connection to Jamaica is in really good shape -- but audio quality on the Jamaica trunk goes downhill really fast as network quality deteriorates. It's *much* more sensitive to network quality than a regular call across the same trunk -- and it becomes more sensitive to network quality as the number of users in the conference increases. On one occasion, a 7-party conference ended because audio quality from Jamaica was unusable. I then immediately called one of the extensions in Jamaica, and audio quality was OK. CPU usage during the 7-party conference was usually 10 to 15%, with occasional peaks at 50%. On a good day, the network path from NJ to Jamaica is about 170 msec with 15 msec jitter (sounds perfect); on a bad day, it's 10% packet loss and 500 msec jitter. Needless to say, the latter condition is always unusable. A one-to-one call is still usable with packet loss of 3 to 4% and 60 to 70 msec jitter (although it certainly has audible dropouts), but a 7-party conference sounds really dreadful. ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

It was up to date with asterisk, but I haven't update the CVS on sourceforge in a bit (nobody had even been looking at it). I've updated it now, and it should compile against the current 1.0 branch. Hmm, looking at the code now, we still don't have an extra parameter there. maybe that was post-1.0? -SteveK

Re: [Asterisk-Users] The maximum capacity of MeetMe
Hi !! all !! As for system specs, I believe that Jeremy's system is based on a dual-processor (P-IV 2.4 GHz) Dell 1750 server with several GB of RAM. My low end box was a 1.7 GHz Celeron with 256 MB It becomes helpful. Thank you very much!!. Key points: (on a server dedicated for conferences only) o number of channels o types of channels o codecs used (and ratio) o number of conferences o number of channels in the conferences I used SIP and bandwidth is set as 100M. It and a codec use G.729. A conference room is 1 room. How many persons can participate in the quality of a meeting? (CPU PenIII 866 [MHz] and RAM 256 [MB]) ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

For example, how many conference rooms can be made from CPU 866 [MHz] and RAM 256 [MB]? Is there any person who tried someone? I am studying MeetMe now. Please tell me a hint!! The answer is 1. That's right, only one conference. The answer is also probably some number greater than 30. Which answer applies to your situation, would depend on how many people are in each conference, what technologies they are using to connect, what kind of hardware is in your asterisk server, and how much bandwidth you have available. Now, go and figure out what you need asterisk to do, then test a configuration you have and figure out what your configuration needs to be. - Andrew Thompson http://aktzero.com/ ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
RE: [Asterisk-Users] The maximum capacity of MeetMe
I regret that I've only used MeetMe a few times, and only up to two users. Perhaps others that are using MeetMe could comment on the number of concurrent conferences and total users they have asterisk running with. The specs of the systems involved would be most helpful. If this is on the wiki, I apologize.
