Re: [asterisk-users] difference between playback and background?
Alternatively, if you don't have that extension defined anywhere, Asterisk will jump to the i extension, where you can then read the actual entered digits from the INVALID_EXTEN variable and jump back to the main part of the dialplan. Note that if they enter digits that *could* match a defined extension, Asterisk won't necessarily jump to the i extension until more digits are entered which may or may not cause no explicitly defined extensions to be matched.

Re: [asterisk-users] difference between playback and background?
First question - playback is not interruptable by DTMF, background is.
You have two options here
Option 1
Use Read
[getnum]
Exten => start,1,read(mydigit,prompt,4,skip,1,2)
.. verification stuff
Option 2
Use WaitExten with Background
[getnum]
Exten => start,1,background(prompt)
Exten => start,n,waitexten(2)
Exten => ,1,noop(user pressed )
Exten => I,1,playback(invalid)
For option 2 you have to define each valid 4 digit entry in the context.
Yes it can be maddening, but you get what you pay for.

Subject: [asterisk-users] difference between playback and background?
In the dial plan language of asterisk, what is the difference between
prompting the user with a Playback() command vs. a Background() command? I
want in a part of my dial plan to ask the user a prompt, and wait for 4
digits to be typed in. I don't want the user to have to end the string with
a pound or something, just wait 2 seconds after they stop typing. ANd I do
want the prompt to be interruptible if the user is fast and knows already
what to do.
I need to do some tests on the number they entered. If i use background(),
and say the prompt, and then follow with a WAIT command, how do i reference
the number they just typed in? does asterisk set the ${EXTEN} variable when
the user types something?
What I find maddening about the asterisk documentation is a lack of clarity
on the sequence of things, and what variables get set when?

Re: [asterisk-users] difference between playback and background?
It sounds like you may want to use the READ command instead. This lets you
hard-set the number of digits to expect and then sets a variable which you
can use later in the dialplan. Generally you use the background command to
let them dial an extension or automated attendant option. Playback plays
without the option to interrupt it.
