[Freeswitch-users] lua, sound playback and interruption on DTMF entry

Hi all, I've got a lua script that plays a sound file then listens for DTMF. What I'd like to do is interrupt the sound file playback and process the DTMF if the user starts entering digits whilst the sound file is playing. At the moment they have to wait til the sound file has finished before entering digits. Any suggestions? Here's the script snippet.. ession:streamFile("/usr/local/freeswitch/sounds/dk/gsm/vm-enter-num-to- call.gsm"); session:streamFile("/usr/local/freeswitch/sounds/dk/gsm/vm-then- pound.gsm"); digits = session:getDigits(20, "#", 3000); Thanks, Alex
