How to deal with user pressing extra keys? flush_dtmf? session::flushDigits?
I'm writing an ivr script in lua, and using playAndGetDigits in a couple different places. Both places just take a single digit to continue on. If the user presses 2 digits, it seems as if the second digit is being queued and it's being processed in the next call to playAndGetDigits. Often the extra digit is invalid, so when it tells the user to press a certain key, it follows immediately with the message "invalid key", due to the extra key being in the "queue"... is this anything I can protect against? I found a flush_dtmf, but it is not very documented: http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_flush_dtmf and I also found this: http://wiki.freeswitch.org/wiki/Session_flushDigits but calling it before and after playAndGetDigits didn't *seem* to help... should it? script here: http://pastebin.freeswitch.org/16584
session:flushDigits() right before you collect DTMF and you will never get any old dtmf On Fri, Jun 24, 2011 at 2:51 PM, Wes <wes-fs@499x.com> wrote:

I put flushDigits right before playAndGetDigits, but it is still queueing up keypresses... if I type more than one key, weird things start happening in my loop. (the one that prompts for 1 - play back recording, 2=submit recording, 3 = rerecord)... sometimes I get the message "invalid response" followed a few seconds by "your recording has been submitted", and I've not typed anything in between. incidentally, if I press a digit while playAndGetDigits is still speaking, it takes a few seconds for it to stop talking and act on the keypress... ... it just doesn't seem very responsive.... which is why I'm testing extra keypresses... because if users don't immediately get a response, they tend to press the key again. script here: http://pastebin.freeswitch.org/16584 On 6/24/2011 3:17 PM, Anthony Minessale wrote:

Hey, that Lua code looks awfully familiar! (I wrote some of that on a snowy day in hotel room in Wisconsin...) Okay, I think I see what you're trying to do. You just want to have the person press 1 to continue. Do you want something different to happen if the person presses a key other than 1? Just checking. Also, I don't see any flushDigits in your script. Try adding this before your PAGD: session:execute('flush_dtmf'); Try again, report back, etc. -MC On Fri, Jun 24, 2011 at 2:06 PM, Wes <wes-fs@499x.com> wrote:

incidentally, if I press a digit while playAndGetDigits is still speaking, it takes a few seconds for it to stop talking and act on the keypress... ... it just doesn't seem very responsive.... which is why I'm testing extra keypresses... because if users don't immediately get a response, they tend to press the key again.

Yes, that is your example modified a bit! I did not pastebin the latest version, but I did have it in there. anyway, it seems to be working better now when I tested it again. My intention is to detect a human, so that if I get a voicemail system, it won't end up recording. Is there a difference between: session:execute('flush_dtmf'); and session:flushDigits() ?
