Your question does not make any sense, and is likely to cause far more confusion to casual readers of this list. In addition, this is not a development question anyway.

There is no "do not support DTMF" for any card, since DTMF detection can always be done in software. Without a hardware echo canceler, no board can do DTMF detection on the board, since there are no DSPs on the board.

As it stands today, the TE407P, TE412P, TE207P and TE212P do not do DTMF detection in hardware, due to some limitations in the firmware of the Octasic echo canceler hardware. The TE406P and TE411P do DTMF detection in hardware, if it is enabled.
