One way might be to create an event loop and listen for DTMF

public bool Load()
        {
            ThreadPool.QueueUserWorkItem((o) =>
            {
                Log.WriteLine(LogLevel.Notice, "Thread Starting. ");
                EventConsumer con = new EventConsumer("DTMF", "");
                while (true)
                {
                    Event ev = con.pop(1);
                    if (ev != null)
                    {
                                  ... do what ever needs to be done
                    }

                }
            });

See http://wiki.freeswitch.org/wiki/Event_List#DTMF

I am guessing the DTMF is "DTMF" so play around with that if it does not work.

There are probably better ways.

What i need to do is listen on a session before, during and after the session is bridged with another call. I know built into FS is the option to listen for *x where x is 0-9 but i really need more than one digit.

I traced the method that listens for the single digit to the command switch_core_event_hook_add_send_dtmf(session, meta_on_dtmf); in switch_ivr_async.c

mod_managed also has the following in the native class freeswitch.
public static switch_status_t switch_core_event_hook_add_recv_dtmf(SWIGTYPE_p_switch_core_session session, SWIGTYPE_p_f_p_switch_core_session_p_q_const__switch_dtmf_t_enum_switch_dtmf_direction_t__switch_status_t recv_dtmf)

The problem is i can't work out how to use it.  I am fine the the first param for the session but have no idea what i need for the SWIGTYPE_p_f_p_switch_core_session_p_q_const__switch_dtmf_t_enum_switch_dtmf_direction_t__switch_status_t recv_dtmf param.

if anyone can point me in the right direction or knows a better way i would be grateful.

Chris
