Okay. I got two replies from Shelby R. and Ken R. I presume these two answers do not conflict? I gather from these replies is that FS has 3 modes: 1) FS is a complete stand-alone system (i.e. FS interacts with media stream), 2) FS is a media_proxy (i.e. FS simply receives/transmits media but does not process it), 3) FS is in bypass media mode where FS tells both endpoints to send media directly to each other (i.e. no media handling packet handling at all). In mode 3), How do the IVR, Voice Mail, Eavesdropping, MOH and central conferencing features work? Would it use an external media server(s)? Also, Ken you mentioned "clusters". What is a cluster? What system(s) are you running the 20K concurrent calls at 2000 calls/sec rate? Which of the three modes are you running the server when recording these statistics?

Remember FS can operate in 3 modes, standard mode where we can do transcoding and interact with the media stream, or proxy_media mode where we just proxy the media packet in packet out, and bypass_media mode where we tell the end points to send the media directly to each other. This allows for some interesting scalability (we have clusters running in excess of 20K concurrent calls at call rates in excess of 2000 calls/sec) _____ From: Jerry Richards <jerry.richards@teotech.com> Reply-To: "freeswitch-dev@lists.freeswitch.org" <freeswitch-dev@lists.freeswitch.org> Date: Thu, 27 Aug 2009 08:45:30 -0700 To: <freeswitch-dev@lists.freeswitch.org> Subject: Re: [Freeswitch-dev] Scalabilty of Freeswitch Also on a related issue (since I am a novice to Freeswitch), regardless of statistics on number of extensions per system per configuration, I had a more general question: That is, does Freeswitch allow for distribution of loading (e.g. supports interface to media servers running on separate machines)? Also, I imagine the SIP signaling part must always be a standalone machine that manages all extensions?

This is very common question based on which many people measure switch capabilities, so in my opinion should be treated with that in mind (as marketing oportunity) Regards, Mindaugas Kezys http://www.kolmisoft.com VoIP Billing and Routing Solutions From: freeswitch-dev-bounces@lists.freeswitch.org [mailto:freeswitch-dev-bounces@lists.freeswitch.org] On Behalf Of Michael Collins Sent: 2009 m. rugpj?čio 26 d. 23:36 To: freeswitch-dev@lists.freeswitch.org Subject: Re: [Freeswitch-dev] Scalabilty of Freeswitch This question sounds eerily familiar...

You can have many hundreds of users, but there are a lot of factors: network infrastructure, call volume, etc. Also, when that number is exceeded, how can Freeswitch server be distributed to accommodate a larger installation? Yes there are strategies. You definitely want a professional to assist if this is a serious production environment. There are members of the FS community who do this sort of thing, or you could email consulting@freeswitch.org to get assistance from the core FS developers. -MC _____ _______________________________________________ FreeSWITCH-dev mailing list FreeSWITCH-dev@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-dev UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-dev http://www.freeswitch.org
