Hi,
Do anyone know how to integrate MT8880 DTMF generator with traditional
2 wires telephone lines? That is, the remaining circuit to interface with ring and tip. I only need the transmitter part.Thanks!

You need whats called a 'Hybrid' to go from MT8880 to POTS. Actually half of one. Plenty of app notes out there. I think National has what your looking for.
You should also look at Part 68.
