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 => 1111,1,noop(user pressed 1111) 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. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Edward de Jong Sent: Monday, November 21, 2011 11:51 AM To: [email protected] 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? -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
