I live in France and the ISP I’ve subscribed to provides a regular phone line along with my Internet connection. Here’s a simple schema of my setup:
Since I don’t use this phone line I would like to switch the regular phone with a computer (preferably running Linux) where I could receive/handle calls programatically. For example, execute a shell script if I press 2, that kind of thing.
I’ve asked this question somewhere else and I was pointed here. I’ve googled around but I didn’t found a really basic introduction to asterisk.
I’m experienced in programming, unix, sysadmin and basic network stuff but I know next to nothing about phones or asterisk. So I would like to know if asterisk can actually do what I want and how. Also, I guess I’ll have to buy a telephony card. Which one should I buy given my very modest need? If you can’t point me to a precise model, just give me the technical requirements of the card I should buy.
