[Freeswitch-users] How to deal with user pressing extra keys? flush_dtmf? session::flushDigits?

[Wes]

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.
