问题

[out]
exten=>_X.,1,Answer()
exten=>_X.,n,Background(hello)
exten=>_X.,n,WaitExten(5)

exten=>1,1,Goto(check,s,1)

Audio menu are playing, but when I press 1, sound stop and after few second check command run. How to quickly respond to a user request?

回答1:

You are doing begginer error which described in almost any asterisk book for beginer.

I recommend you read "Asterisk The Future of Telephony" by O'Relly.

This exact error is simple:

• in your dialplan you have extension _X., which mean "any number starting with digit.
• you ask asterisk waitfor extension selected in this context.
• you are pressing digit, but acordinly to context you may want enter 1111(also fit you context). So asterisk wait upto TIMEOUT(digits) until you enter next digit.
• your timeout is 5 second, so it go ext 1 in 5 second.

[Syntax]

BackGround(filename1[&filename2[&...]][,options[,langoverride[,context]]])

You can use other context for matching.
