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.

Unmute when we get a dtmfup (we muted on dtmfdown) event.

This would occasionally cause one-way audio when using hardware DTMF
detection.
