Yes, they all refer to revision numbers inside our internal repository.

Unfortunetly I'm afraid that this specific fix is not goin to help you.
It was an internal fix in a new feature regarding to hardware-based DTMF
detection in our driver.
Anyway, your question is a good question for asterisk-users
nevertheless.

Are the digits sent inband in the PRI channel or out-of-band as
signalling? (Or both?)
You can check if the DTMF digits are sent inline in the PRI by listening
to the specific channel (e.g: with ztmonitor).
You can check if they are sent out-of-band using 'pri debug span N', I
guess.
