Assuming you're in the United States and getting POTS service directly
from the telco, chances are really good it's FSK-based.

To check with a buttset, hook it up to the pair and monitor as you call in 
from another phone.  If it's DTMF, you'll hear DTMF.  If it's FSK, you'll 
hear a squawk much like a packet radio transmission or the data bursts you 
hear on weather radio when a warning is issued immediately after the first 
ring.  -rt
