Call to Number after extension answer

Hello Friends , Well , i m here again … the question is .

Is there a way to call to extension , so that answer , “please , digit the number that you want to call” (i got the sound), and than call from SIP Trunk or Dahdi after that ?

Call 444 >
Automatic Answer : Please digit the number >
Digit 88888888 in my softphone >
Call from SIP Trunk to 88888888 . >

I cannot think about how can we do that , but i m tryng to do something like


exten => 444,1,Goto(external,s,1)


exten => s,1,Answer
exten => s,2,Background(digit)
exten => s,3,WaitExten(10)

exten => _X.,1,Dial(SIP/${EXTEN}@trunk,50)

Thank you very Much
