I'm familiar with Networking, VoIP, Asterisk and Linux... but I've never deployed a VoIP with PSTN.

I've got one week to deploy VoIP + 2 PSTN numbers, I don't mind reading like crazy but I would like to get a recommendation on what hardware to buy (not the specific model, but just the specific kind of hardware), like "you need a X card with Z ports" or something like that.

I guess I need some kind of FXO/FXS card connected to my server with maybe 2 ports (the numbers are going to be analog, but the phones are going to be IP).

I could buy a card and then spend my time setting it up, but of course I don't want to buy something that's just not going to work.

You're correct that you need an FXO/FXS card presuming that your phone lines will be analog. I've used cards from both Digium and Sangoma. I'd recommend sticking with the major manufacturers of these cards for Asterisk as this is your first setup and you want it as simple as possible. Digium will be a little simpler but I'm partial to Sangoma cards as we've not had any reliability issues with them.

The analog cards you can buy from the manufacturers I recommend are module so you typically start with a card that has 4 physical ports and you plug in the modules you need. Just remember that to connect your system to the pstn you're going to need "FXO" ports on the cards.
