Hi all. I've being reading posts from the list since yesterday and I feel this question was answered a lot time ago, but the list archives are a mess (yet). I hope some one is willing to help me out. I want to set up this: caller ----- PSTN ---- (SOMETHING1) ------ VoIP --------- (SOMETHING2) ---- PSTN I think this must be a very basic architecture, but I'm not sure wat SOMETHING1 and SOMETHING2 are. I've been on this for a while now (around two months) and till yesterday I haven't find Asterisk. Can you help me? I need to know hardware and software needs for this. I have read a few about voIP and have some programming and configuration skills under Linux and Windows. Thanks in advance. RODOLFO --- avast! Antivirus: Outbound message clean.

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.

An FXO port could connect to an analog extension on your PBX too. Thinking of PSTN lines and telephones can limit the thinking of a newbie to just PSTN lines and analog phones. There are MANY ways you can use FXS and FXO ports to connect devices togather.
