As usual, if you want to ask a smart question you need to add more
details. 

DTMF can be caused by "talk off". Essentially a voice pattern that
triggered the DTMF detection. Now for the part that would have been
smart, identifying the location your DTMF is being detected. If it where
all zap, then it is the DTMF routines in asterisk/zapata, but as you
didn't bother to expound what is going on, it could be SIP hardware
phones acting up on you.

More details please before you go batty.
