Summary:                    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.

Did some bisecting in the 1.6.1 branch.

Versions before r134260 fail to build with current DAHDI.

That version and on exhibits the problem.
