Dial plan


I am having problem in dial plan when i have call a extension which is busy asterisk will play no body available instead of playing extension busy.
my extensions.conf setting is

exten => 222,1,Dial(SIP/222,40,Tt)
exten => 222,2,Playback(vm-nobodyavail)
exten => 222,3,Hangup()
exten => 222,102,Playback(tt-allbusy)
exten => 222,103,Hangup()


The newer versions of Asterisk have priorityjumping off by default.

See http://www.voip-info.org/wiki/index.php?page=Asterisk+cmd+Dial for more information.
