The answer is no. With Analog Feature Testing (AFT), user can only send OR receive DTMF digits in a single action. It is not possible to use a single action to send AND receive DTMF at the same time. If users want to test this functions, they have to use the "non"-AFT feature. Essentially they have to configure two scripts, one for the originating side, and the other for the terminating side. With that, users can then configure a SEND DTMF action on one side, and a RECEIVE DTMF action on the other side.
