JTAPI 1.2 / XTAPI DTMF Tone detection

Hi all,

I'm new to JTAPI and I need help with DTMF tone detection.
I've got a simple class that makes a call to my mobile phone.
I get notified on call events:

Connection to Address: 0 is INPROGRESS

Connection to Address: 0833055676; is ALERTING

Connection to Address: 0 is CONNECTED

Connection to Address: 0833055676; is CONNECTED

When I receive the ConnConnectedEv I also enable DTMF:
...
mtc.setDtmfDetection(true);
...

and I check for MediaTermConnDtmfEv:
...
else if (evlist[i].getID() == MediaTermConnDtmfEv.ID) {
            System.out.println("MediaTermConnDtmfEv");
            /* Print out the DTMF digits */
            char digit = ((MediaTermConnDtmfEv)evlist[i]).getDtmfDigit();
            System.out.println("detected DTMF: " + digit);

            TerminalConnection tc = ((TermConnEv)evlist
[i]).getTerminalConnection();
            MediaTerminalConnection mtc = (MediaTerminalConnection)tc;

            try{
                // Echo out the same digit we detected
                mtc.generateDtmf(digit + "");
            }catch(Exception e){
                System.out.println("Exception generateDtmf: " + e.toString
());
            }
          }
...
Somehow I'm not getting DTMF events.
My program doesn't detect when the call has been hung up by remote
terminal either.

Any help would be greatly appreciated.

Thanks,
Enrico
