Sure, you'll have multiple systems to maintain, but they will be smaller, less complex systems. Also, since each company is unrelated, there is little benefit to having them all on the same server (no need to dial between offices, etc) I agree. You have an exact multi-tenant setup. I would take each of the E1 connections and plug them into a server, one for each floor. If one of the servers runs out of connectins on its E1, then it can use the outbound lines from an * for another floor. You do not want the entire building to have an outage. You happen to have 8 E1 and 8 floors, right? If not, then you can have any floors that don't have a direct E1 connection dial out through the * servers that do have an E1. Also, *do not* run fax over SIP if at all possible. You will need channel banks to handle the faxes. Setup a hylafax server so each tenant can receive faxes over email, and send them from their computers, or just strike up a deal with efax for the building.

Vedran Dakic ha scritto: How does Asterisk handle this kind of setup with one-two/cluster central server(s) and a bunch of other servers connected with IAX(2)? If you have local calls, do they go directly from phone to phone, do they go from phone to per-floor-Asterisk server, or they have to be interconnected via the main Asterisk server(s)/cluster? With SIP the default is to directly connect the phones once the call is setup (I think also in IAX), investigate canreinvite / nat. Of course you can't do call detail record for calls which aren't forced to pass from the server, see if it's a problem ... As for maintenance we have a dozen of pcs with asterisk installed, each of them is server for 8/10 sip phones and client to a central asterisk server which then connects to E1. Asterisk pcs are scattered around, they pass trough at least one natted network, usually two. Never a problem. Connecting all the SIP phones to SER load balancing to more than one asterisk server will make you learn a lot about sip internals, proxy, domains, authentication and other interesting stuff, but if you need to have a working sistems and can start from zero go iax and spare yourself a lot of frustration. ___ --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

RE: [Asterisk-Users] A rather big setup.
I'm very aware of the maintenance issue, but it would also give me a great deal of freedom for some various other things as well. This of course depends on the Asterisk architecture, which I'm not completely aware of - in detail anyway. How does Asterisk handle this kind of setup with one-two/cluster central server(s) and a bunch of other servers connected with IAX(2)? If you have local calls, do they go directly from phone to phone, do they go from phone to per-floor-Asterisk server, or they have to be interconnected via the main Asterisk server(s)/cluster? I mean, there's little point of doing this kind of setup with dedicated Asterisk servers on each floor if you don't get your central server/cluster free of some work - at least of internal calls. Also, it kills scalability, which is always an "issue". Anyone? Cheers, Vedran.

RE: [Asterisk-Users] A rather big setup.
> 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 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".

[Asterisk-Users] A rather big setup.
I have been asked by the customer to deilver a big PBX-system based on Asterisk. The requirements are approximately: - up to 240 lines for making outside calls from the building - up to 1000 internal phone conversations (within the building) - scalable up to 300/1500 calls Does anyone have any ideas about a setup like this? How much servers should I use, should I use clustering, what E1 cards, how many, etc? Any help would be mostly appericiated. ___ --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
