Ok i go from ivr option 9 that works well , then i need to dial out with my internation provider, i suppose WaitExten Sets ${EXTEN} variable so i dial out with it, but when i start to dial my first number is executed immidiatly. I got the i extension, so it is executed if no exten found. WaitExten is Not wait till i finish my number.

exten 9,1,Answer()
exten 9,2,WaitExten(8)
exten 9,3,Dial(Sip/${EXTEN}@myprovider,60,t)
