Most of Asterisk's AGI commands can be interrupted by pressing a DTMF dig=
it.
Which - if any - DTMF digits should cause an interruption can be specifie=
d
via the escapeDigits parameter of many of AbstractAGIScript's methods. Th=
e
singe character that those methods return corresponds to the digit that
has been pressed to interrupt the command.
There is no way to say "Abort this command only if user presses DTMF digi=
t
2 after he pressed DTMF digit 1".

If you want to read DTMF digits for further processing, you can use the
GetDataCommand. See
http://asterisk-java.sourceforge.net/apidocs/net/sf/asterisk/fastagi/comm=
and/GetDataCommand.html
The corresponding getData() methods are available in Asterisk-Java
CVS-HEAD, but you can as well use the GetDataCommand with Asterisk-Java
0.1 vial channel.sendCommand()

I'm getting an error with using sendCommand(GetDataCommand).  I'm not sur=
e=20
if this is an asterisk problem or if it's a asterisk-java problem or if i=
t's=20
a provider problem.

Occassionally, when executing the script, dtmf input is recognized, and t=
he=20
AGIReply will always list the response as null (timeout).  This will then=
=20
happen for the duration of the call, even if subsequent Get Data commands=
=20
are executed.

This put the provider and asterisk at the top of my list.  However, I had=
n't=20
had that problem with any of my providers prior to switching over to usin=
g=20
AGI script.

Any ideas what might be causing this?

That sounds odd. However if this only happens from time to time I am
almost sure it is not an Asterisk-Java problem.
What type of channel do you use in this scenario? (IAX2, SIP, Zap, ..?)

Did you process DTMF prior to switching?

I'm using IAX2 channels, but it seems sporadic... I just wish I could 
reproduce the error so I could get some more details.  I've run 30 tests or 
so in a row w/o hitting the error again, but it has happened to me about 3 
times total on 3 different providers on 3 different days.

Before switching to AGI script, I simply relied on the extension being 
inputted.  i.e. a user hitting '123' would be routed to exten => 123,1,... 
Now, I'm trying to use the Get Data to check for 123.

Another thing I should mention is that I'm stringing a couple of Get Data 
commands together to play different wav files.  Would this cause any 
problems?

Hmm.. I'm also setting the timeout to 1 ms for the files that I'm streaming 
that are immediately proceeded by another streaming file.  Would this cause 
any issues?

I wouldn't use Get Data in that case but rather just Stream File. You can
provide escape digits to stream file so you can interrupt it. I think
thats a cleaner solution.

Right, but the escape digits only allow for a single dtmf input, correct?

yes, but if you detect that the user escaped you can read the missing
digits via waitForDigit

I'll give that a try.  If there are still any missed dtmf, it'd probably be 
an asterisk issue.

Thanks again,
