ISDN and a cheap ATA. No other cards needed for me.

ISDN I understand for the exchange lines, but how would you connect the
phones? or are they ISDN phones?

The ATA is an analogue telephone adapter, essentially an ethernet/PSTN
connection, different ones allow connection to phone(s) and/or line(s),
(oftern called FXO and FXS), asterisk can send calls to them for your
extensions.
