Read any keypress using asterisk

I think you need to listen for ChannelDtmfReceived event and check if it is the same originated channel . You can get digit value from that input.

You can use either. Both will provide you same result.

Well,

Doing this with ARI is indeed a cool thing - but mildly counter productive (yes, this is an ARI library, but sometimes for simple stuff - Asterisk dialplan is preferred).

Using the dial application and the U(x^y^z) option, you can create a situation where a call is received by Asterisk, then a second leg is originated to the receiving party - but a dialplan subroutine is executed on the receiving party channel, prior to bridging the two channels.

    U(x[^arg[^...]]): 
        x - Name of the subroutine to execute via Gosub
        arg - Arguments for the Gosub routine
    Execute via Gosub the routine <x> for the *called* channel before
    connecting to the calling channel. Arguments can be specified to the Gosub
    using '^' as a delimiter. The Gosub routine can set the variable
    ${GOSUB_RESULT} to specify the following actions after the Gosub returns.
        ${GOSUB_RESULT}: 
            ABORT: Hangup both legs of the call.
            CONGESTION: Behave as if line congestion was
            encountered.
            BUSY: Behave as if a busy signal was encountered.
            CONTINUE: Hangup the called party and allow the
            calling party to continue dialplan execution at the next priority.
            GOTO:[[<context>^]<exten>^]<priority>: Transfer the
            call to the specified destination.
    NOTE: You cannot use any additional action post answer options in
    conjunction with this option. Also, pbx services are run on the peer
    (called) channel, so you will not be able to set timeouts via the TIMEOUT()
    function in this routine.
