Many of you, like me, have looping Background(), Wait(), and Goto() application priority chains that prompt users to enter some data, and then repeat the instructions if no keys are pressed. The problem of course is if the user doesn't start pressing keys during the Background() call and delays until the Wait() application is called, those keys are lost.
I had solved this some time back by creating a few random length files of silence, that would replace Wait() routines in some circumstances. I have finally created a formal measured group of files, each with 1-10 seconds of silence, and put them in my sounds directory for public consumption. Not a big deal for most of you to create these files yourselves, but perhaps a minor pain that hopefully I've removed for some people who don't have sound tools handy.

And you missed the right way to deal with this. You may have to break your extensions into more contexts, but you let the timeout function do it's work.
[learning_the_way] exten => s,1,DigitTimeout,5 exten => s,2,ResponseTimeout,10 exten => s,3,background(instructions) exten => s,4,background(more_instructions)
exten => t,1,Goto(s|3)
This will let the call progress through the backgound apps, and if it falls out of these rules, then it waits 10 seconds and falls into the t extension where you can do whatever you like even going back and repeating the instructions.

No, I didn't quite miss that method, but your example is useful in certain circumstances.
There are instances where you have pauses in between voice prompts that are not necessarily looped; I did not include in my message all possible iterations of why these silent gaps might be required, but since that is non-obvious, I include an instance below. It could be done with multiple contexts or meta-extensions, but I feel that is inelegant and confusing when it need not be. There are multiple ways to do things with Asterisk; not all of them fall into definitions of the "right" way for all administrators.
