Look long and hard before purchase of a TDM400 It doesn't work with many motherboards, and Digium's anser is "try another Motherboard"
Seriously consider the Sangoma A200
5 year Warranty and works with all motherboards.

I'm preparing for my first asterisk install, and would like to ask a hardware question & confirm my understanding of some basics:

    * The Q: I'm looking for 2 FXO ports to have asterisk answer 2
      incoming lines. There are single FXO port cards for about
      $30...  but dual cards, or the Digium "400" cards, are all
      several hundred dollars. Why is this? Are the chipsets so
      different, or am I missing something?

And here's my plan to teach myself using increasing complexity:

    * Starting point is standard PC, standard phone line
    * do trixbox install on PC & connect to LAN (no special hardware yet)
    * then I should be able to setup IVR and voice mail boxes, and
      access them using a "soft phone" from any PC on the network, but
      only"locally", using extension numbers, right?
    * I could also plug IP phones directly into the network and access
      the asterisk box "locally", using extension numbers, right?
    * add FXO card(s), and connect incoming lines. Now I can also:
          o dialup the voice mailboxes from any standard phone worldwide
          o Use any of the IP and/or softphones to send and receive
            calls via PSTN, right?
    * add FXS card(s) and I can plug standard phones into the asterisk
      box and I can use them as extensions, to either access voicemail
      locally, or send/receive calls via PSTN ... right ???
    * Now for VoIP I just have to order the service from a vendor like
      vonage, and I can use any of the soft phones, IP phones or
      standard handsets for VoIP... right ??

Do I have any major misconceptions about the above?

Thanks a lot for your patience !!!
