You can use asterisk and implement an IVR flow using AGI php scripts.

Asterisk is an open source telephony project. You install the software on a linux box, then you connect some phone lines (PSTN, ISDN, SIP, whatever).

Asterisk can be controlled by using AGI php scripts to build custom interactions (dial number XXX, play wave "Press one to do this, two to do that", read DTMF input from user, etc).
