Hi, could you give me some example of what's necessary to collect DTMF digits during audio file playback and how to return collected data to my web application? I'm sorry but even after reading FS 1.2 book I don't know how to do that. 
Here's my application's httapi script:

<document type="text/freeswitch-httapi">
    <work> 
<pause milliseconds="2000" />
        <playback file="http://wypas2/simver/audio/test2.wav" name="digits"
            digit-timeout="5" input-timeout="15" loops="3" terminators="#"> 
            <bind strip="#">~\\d{3}</bind >
        </playback>
        
    </work>
</document>

but i don't see the collected digits anywhere in request parameters coming from FS. 

Thanks
RG
