[Freeswitch-users] Lua playAndGetDigits

[Michael De Lorenzo]

I'm having some trouble getting consistent results with playAndGetDigits,
sometimes the digits are record and other times they're not.  It seemed to
have something to do with how quickly the digits were pressed, but now that
no longer seems to be the case.

I'm trying to have users press a confirmation code, in this case "1111"
although I'd like to make it accept "1" or "11" or "111" or "1111" if
possible.

Can anyone point me in the right direction?


    session = freeswitch.Session("{ignore_early_media=true}sofia/gateway/"
.. provider .. "/1" .. number_to_call);

    while(session:ready()) do
       session:answer();
       session:setInputCallback("onInput","true");

       --playbackMessage(check_message);
       digits = session:playAndGetDigits(4, 4, 1, 5000, "",
get_digits_message, "", "[1]");
       freeswitch.consoleLog("info", digits .. "\n");
       freeswitch.consoleLog("info", "Did this check out? " ..
(check_message == true and "yes" or "no" .. "\n"));

       -- we got what we're looking for, so we can end this
       if(check_success) then
          freeswitch.consoleLog("info", "A positive response was received
from this check.\n");
          break;
       else
          -- not a positive response
          -- if we reached our max attempts, we're finished move on
          if(attempts == max_attempts) then
            freeswitch.consoleLog("info", "We've reached our maximum
attempts for this number.\n");
            break;
          end
       end
    end
