9 thoughts on - Pattern Extension Not Working In Dialplan

• The first issue I see is you are attempting to insert your pattern match in the middle of your ‘s’ extension, That’s going to break your ‘s’ extension.

  The second issue is that you are matching on XX which will match two digits, You need to match on _X instead if you are attempting to match on the number 8.

  I recommend you look into ‘read’ instead of trying to do a pattern match.

• Disregard that. I can’t even follow my own advice (‘dialplan show macro-age’). Don’t ‘intermingle’ extensions.

• ​Thank you all for your suggestions.

  1. [macro-age] is a macro and not an extension badly named.

  2. I am able to use Read to fulfill the purpose but we can’t use Read()
  after Background(). To use read we need Playback() [ am I right?]. But Playback do not provide barge-in facility i.e. user have to listen whole message then only his inputs will be accepted and if he entered input during the time recording is played , the input will be lost. So if using Background() [which return the control immediately] I have to use _XX extension.

  3. So basically I want to create a dial-plan where user is asked to input multi-digit value and he can enter it without listening complete message
  (if the user knows the message already)​

• You would be better off jumping to a new context and building up your number, digit-by-digit as it is entered, in a channel variable.

  In your “s” extension, set your variable to an empty string; do a Background()
  and then WaitExten() for a digit to be entered. Have an extension _X to capture each digit and append it to the number so far. Then use a GotoIf() to jump to the WaitExten() statement if insufficient digits have been entered so far. You might also want a * extension to clear the number entered so far, if the user makes a mistake.

  If you need a written example, I might be able to dig something out later.

• Thanks for the suggestion.

  @Stiles – Look like this may work. Will try this. Thanks.

• @A J Stiles : If you could provide an example as you said, It would be very nice. Thanks.

• This is excerpted from a dialplan application I wrote. It’s actually a PIN
  entry but should be usable for any general purpose application. Sound files referred to will need to be created by you.

  [get_pin]
  exten => s,1,Set(pin=)
  exten => s,n,Set(PINLENGTH=4)
  exten => s,n(prompt),Background(ajs-enter_pin)
  ; Build up the PIN digit by digit. The WaitExten() will be cut short by any
  ; keystroke, so we can use a quite longish timeout. exten => s,n(nextdigit),WaitExten(30)
  exten => s,n,Playback(ajs-sorry_didnt_get)
  exten => s,n,GoToIf($[${LEN(${pin})}<1]?prompt:saysofar)
  exten => s,n(saysofar),Playback(ajs-digits_so_far)
  exten => s,n,SayDigits(${pin})
  exten => s,n,Goto(nextdigit)

  ; We need a “h” extension (for tidying up after ourselves) in this context;
  ; because the call may be placed from within this context.

  exten => h,1,NoOp(Clearing up)

  exten => *,1,Playback(ajs-start_again)
  exten => *,2,GoTo(get_pin,s,1)

  exten => #,1,Hangup()

  exten => _X,1,Set(pin=${pin}${EXTEN:0:1})
  exten => _X,n,NoOp(PIN so far is ${pin})
  exten => _X,n,GoToIf($[${LEN(${pin})}>=${PINLENGTH}]?got_all:need_more)
  exten => _X,n(need_more),GoTo(get_pin,s,nextdigit)
  ; We have all 4 digits ….. exten => _X,n(got_all),NoOp(PIN is ${pin})

• ​Thanks. I will try it. Meanwhile I was trying below code.

  call goes to ‘test’ context and from there is passed to macro ‘age’. In ‘age’ macro when I am using any patter to accept even single digit, its not working. So instead of using pattern I hardcoded the extension, but still when I am pressing the key ‘2’ it is throwing below error. Please note that when diaplan execution is inside macro ‘age’, it searches the extension inside its parent context ‘test’…why? am I do something wrong?

  [test]
  exten=>s,1,Macro(age)

  [macro-age]
  exten=>s,1,Background(my/age)
  exten=>s,2,WaitExten(15)
  exten=>s,3,NoOp(${AGE})
  exten=>s,n,GotoIf($[${LEN(${AGE})} > 0]?notEmpty)
  exten=>s,n,Goto(s,1)
  exten=>s(notEmpty),n,Background(my/thank-you)
  exten=>s,n,Wait(1)

  exten=>2,1,(TEMP=${EXTEN}) ;; exten=>_X,1,(TEMP=${EXTEN}) is also not working exten=>2,n,Read(AGE,,1,10)
  exten=>2,n,Set(AGE=${${TEMP}*10+${AGE}})
  exten=>2,n,Goto(s,3)
