Have you used a mobile phone when you test the "fast speed DTMF sequence"? We have found that in GSM network DTMF digits are sent out-of-band from the terminal (despite the tones generated by phones) and are "injected" in-band into the audio channel _but_ with some delays between digits. At least this is the situation in Romania (Vodafone and Orange GSM networks).
