You might be reading out of date documentation. In 1.2.14, if you don't have "priorityjumping=yes" in extensions.conf and you don't activate priority jumping for an individual application (for Dial(), you add "j" to the options string), then the jumping behaviour you are expecting to happen (n+101) doesn't happen.
<br><br>If you don't want to do this via priority jumping, you can branch based on the ${DIALSTATUS} variable:<br><br>exten => s,n,Dial(${ARG2}|20)<br>exten => s,n,Goto(s-${DIALSTATUS},1)<br>exten => s-NOANSWER,1,Voicemail(${ARG1}|u)
<br>exten => s-NOANSWER,n,Hangup<br>exten => s-BUSY,1,Voicemail(${ARG1}|b)<br>exten => s-BUSY,n,Hangup<br>exten => _s-.,1,Goto(s-NOANSWER,1)<br><br>This is part of a macro invoked as Macro(mailbox,channel), but you get the general idea.
