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

[Alex Kinch]

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
