<p class=MsoNormal><font size=4 face=Arial><span style='font-size:14.0pt;
font-family:Arial'>I need to be able to play a file and collect digits at the
same time. I detect the digits via the DTMF Events on the AMI interface. I
use the Get Option command to start the play. However, I encountered a slight
timing bug. Asterisk can detect the DTMF digit at the same time our
application is sending a Get Option Command. The result is that my application
sees the digit, which is exactly as expected. When this occurs, I want to be
able to stop the play, but I have not been able to find any AMI, AGI command,
or Application to allow us to abort an existing play.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=4 face=Arial><span style='font-size:14.0pt;
font-family:Arial'>Some vendors have an internal digit collector. When a play
is initiated, several options are passed in (# of digits to collect, clear
existing digit queue flag, timeout, etc).<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=4 face=Arial><span style='font-size:14.0pt;
font-family:Arial'>Other vendors provide events to notify the application when
a digit is pressed/released. In this environment, the application is
responsible for most of the work. The key feature is that provide a way for
the application to be able to stop the play.<o:p></o:p></span></font></p>
