Luz,

Yes, this is possible with Asterisk. You probably already have a database system with predictive numbers to call, so you'll need some development to talk to that.

For the Asterisk servers, this depends on quite a few factors such as what phones you're using, what database you're talking to, etc. You're probably looking a several modern server PCs, but you do need to plan your requirements in more detail first.

You could use digium cards, but you'd need 13 TDM04B cards, which is not very practical. You're probably better of using E1/T1 cards in the Asterisk servers, then a channel bank to split this out to analogue lines. If you really want to do it right, get rid of the analogue lines to the outside world, and use E1s or T1s.

For a project of this size, you definitely need professional help. The amount you spend will be much less than the cost of 50 operators sitting idle if the system breaks. My company does Asterisk consulting - drop me an email off list if you're interested.
