In terms of using asterisk to implement your diagram, "something1" and "something2" are basic linux boxes equipped with: - pstn interface card (such as x100p, tdm, isdn, T1 card) - ethernet interface (to connect to your broadband internet) - asterisk software The type of pstn interface card to use will be dependent upon how many "simultanous" phone conversations you'd like to support. The x100p card is a single pstn line interface; the tdm card supports one to four (tdm04b bundle) pstn lines (the tdm card needs to be purchased with fxo interface modules); the isdn card supports from one to 23 (?) pstn logical interfaces (depending upon the exact card purchased); or the T1/E1 card supports from 1 to 24 (T1) or 1 to 32 (E1-?) conversations. You'll find most of those cards at www.digium.com under Hardware Products. If you are outside the US, consider the TDM card as opposed to the x100p card. The size of Linux system will also be dependent on how many simultanous calls you want to support, and exactly how you have the system configured. For a single call, some folks have it running on old 300 mhz (and slower) box, while high traffic volumes will require a much faster system. The asterisk software can be found on the digium home page (lower-left menu option), which points to www.asterisk.org Also, lots of good reference material at www.voip-info.org After you've configured your system with your favorite Linux distro, download and compile asterisk per the instructions found on the www.asterisk.org site. Pay attention to the last steps on your screen that copies configuration samples to /etc/asterisk. Read through those configuration files, read the info at www.voip-info.org, and you should be able to get a system running. _______________________________________________ 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
