  That's what I understood, now I know for sure.

  This gives way to a followup question.  Why would digit I enter NOT be
  passed or detected from an IAX2 connection?

  My guess is call quality between the caller and the VOIP DID provider.

  Caller Phone (MaBell, Mobile phone) --> DID Provider --iax2--> Asterisk

  If the connection is bad between the cell phone and did provider, tones
  may not be "heard" correctly, right?

  Once within an iax2 connection, DTMF tones are almost impossible to NOT
  work, correct?

Thanks Russell!
