Remember that the E1 only gives you a 30 lines from each floor then!
If you use a dedicated 100mbs ethernet and uses IAX trunks you can have much more lines from each floor.
Just my 5 cents. Best regards--On Saturday, November 26, 2005 12:35:16 PM +0100 Vedran Dakic <[EMAIL PROTECTED]> wrote:
You mean 240 / 1000 simultaneous calls or 240 outside lines and 1000 internal phones ?I can only guess that I should have the ability to deliver a solution that can do some 100/500 simultaneously. The only question is how powerful should be a machine (or machines) that could do around 100/500 simultaneously. And, just for the sake of knowing, what should the setup be alike if it was 240/1000 simultaneously?In the second case there's no need for a cluster, a good server will do, (obviously a second server for backup is a good idea ). I'm assuming you can use a/ulaw to transmit the data, if bandwidth is a problem and you must compress cpu usage becomes a boottleneck to keep in mind.A/ulaw? I saw some reports that G.729 uses very little bandwidth and has a quality part granted (audio quality). It's not a question of hardware and/or CPU power, I have two dual Opteron configurations and could install some more, it's just the question of that setup running with quality audio and no unwanted events. I presume that I should have all of the phones using the same codec (so, no transcoding), and preferrably the same VoIP protocol. I have a choice there so everything's possible. Let's say - IP10s has H.323, SIP and MGCP firmwares, although I'd like to leave H.323 out of the story.I'm having ~80 concurrent calls from iax/sip to pri in alaw from an userbase of ~150 clients and the cpu is around 6% on a dual 2.8 Ghz. 1000 phones are a lot, and sip sometimes is an hassle (mostly nat), I don't know your network topology, but maybe you can consider to connect every group of phones to an asterisk pc and the pcs to the server via iax, which uses a little less bandwidth and most of all works "out of the box". A pentium 400 can handle ~8 calls with ilbc, so every modern pc will do.Maybe I have a better idea, now that I come to think of it. Maybe I should install one Asterisk server per floor (8-9 floors) and use IAX to connect to the central server with E1 connections. Does that sound reasonable? _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
