[Freeswitch-users] Getting terminator value from PlayAndGetDigit

Hi, I am looking for ways to extract the actual "terminator" value being pressed by user in the case where user can press # or * to signal the end of DTMF input. By extracting this "terminator" value, I would be able to perform action accordingly. For instance, if * is pressed, it means the user is aware that he/she has entered the wrong number and would like to retry. Could someone tell me if it is something possible within Freeswitch? Thanks, Keith
