Summary:                    [patch] 1.6.1: unidirectional PCM if (FXS?) hardware
DTMF detection enabled
Description: 
The following is seems to be a regression between 1.6.0 to 1.6.1 . Tested
it locally with Astribanks and also heard it reported with Sangoma A200
cards.

In this case, the caller does not get PCM once the call is established.

Workaround: disable hardwqre DTMF detection in the driver.

Btw, after looking more at the code, I think that confmute(p, 0) should be
not in the zt_handle_dtmfup but in the zt_handle_event instead (in the if
which handles ZT_EVENT_DTMFUP - right before "return f;")

This way "unmute" code for the case of hardware-detected DTMFs will be
close to the code which makes the "mute" call. 

tzafrir, could you please test if it works because I still do not have the
board with h/w detection. Thanks.
