pppd will do it, you can read http://www.tldp.org/HOWTO/PPP-HOWTO/ or similar

generally you'll need to know routing and networking, pppd options and
chat options.

Then you need to set pppd/chat (pppd starts chat to control the modem)
to wait for a RING, answer the modem, then pppd takes over and
establishes the ppp session.
