Issues:
Environment:I am running a Ubuntu 12.04, I have downloaded 1.8 asterisk version, build was successful. I have configured chan_dongle to work with a voice enabled dongle. Marked as Major since setting the variable is a essential feature for the read application. Without that its a useless app.Attachments:( 0) debugLog.txt

When I make a incoming call, and put punch in a code I get following results only in " entered" as a result.
When I send a sms to this number, it fills up sms.txt with the sms and the source number correctly.
Basically pincode variable does not get a value on the read application.

exten => sms,n,System(echo '${STRFTIME(${EPOCH},,%Y-%m-%d %H:%M:%S)} - ${DONGLE} - ${CALLERID(num)}: ${SMS}' >> /var/log/asterisk/sms.txt)

In order to help troubleshooting this issue, please attach debug logs.

https://wiki.asterisk.org/wiki/display/AST/Collecting+Debug+Information

The READ application appears to be working from my testing.  Perhaps the debug logs will help show what is happening.

One thing I notice is that you are not outputting to a file like in the other two extensions sms and ussd.  You are simply doing "echo".  For troubleshooting, I put a NoOp in there instead of using System and I do see that pincode variable is being set properly.

Here is the myDebugLog contents. I dialed the number, dongle answered the call and played the voice prompt. After that same result, no dtmf.

READ application is saying that nothing was entered.  I don't think there is anything wrong with READ, perhaps the problem is in the third party driver you are using.

It looks like you are using chan_dongle, is that correct?  Please check their wiki page that has some options for debugging problems with DTMF.

My dtmf value in dongle.conf is

dtmf=relax

I also tried off, inband. Did not work. Same thing, dtmf variable not set on read application in dialplan.

I just also tried 'tail -f /var/log/asterisk/myDebugLog' and while I was punching in the keys no response. So guess the issue is somewhere in recognizing the dtmf signal from my mobile phone (HTC Wildfire Android 2.3.6)

app_read is fine.  I used that exact dialplan snippit against a Digium phone connected via chan_sip.  It's a problem with chan_dongle or the device attached to chan_dongle.  Since that's not a channel driver that's a part of Asterisk, I recommend closing this issue in the Asterisk issue tracker and referring instead to the authors of chan_dongle.

Just like Malcolm stated, app_read is working fine.  I have tested it and Malcolm has tested it.

Since this driver is not part of Asterisk, we are unable to provide any further support.  Please contact the authors of chan_dongle for further help in getting the driver to read input from your device.
