exten => 222,1,Answer
exten => 222,2,Wait(1)
exten => 222,3,Background(beep)
exten => 222,4,Dial(SIP/2030@2030)

Above 4th line [  exten => 222,4,Dial(SIP/2030@2030)  ] works

but when I use exten => 222,4,Transfer(SIP/2030@2030) it doesnt work...
May I know why?? am I doing something wrong??
How to transfer a call???
