I would try to stretch out the length of the DTMF digits.  I have noticed that 
PlayDigits' digits are awfully short, I imagine that they're equally short 
out of the zap interface.

The default length appears to be either 100ms or 800ms, I'm not sure which.

from zaptel/digits.h:
#define DEFAULT_DTMF_LENGTH     100 * 8

I'd perhaps try changing that value to 250 or even 500 -- Note that I have not 
done this myself before, I am merely guessing.
