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
