My psychic friend says he's using a compressed codec (G726 maybe) and 
using inband DTMF.  Obviously he should be using RFC2833 if he is using 
a compressed codec.  Heck, I use RFC2833 even for phones that use ulaw. 
  It does not hurt as long as both the phone and Asterisk know what DTMF 
mode to use.
