[asterisk-r2] openr2 - hearing dtmf tones after answering

[Moises Silva]

Unless you are using DTMF R2, the DNIS is not transmitted using DTMF, but
MF.

Also, in both MFC-R2 and DTMF-R2, by the time Asterisk is notified of the
incoming call, the full DNIS and ANI were already transmitted, so there is
no chance you will hear them.

I would say that DTMF is coming from the other party.
