[Asterisk-Users] Help on second dial

[David Lung]

Hi, all 
I'd like to configure Asterisk to receiving call from
PSTN. After PSTN phone call in, Asterisk will prompt
user to enter a number, then Asterisk will 
transfer the call to a SIP phone by this number. 
Please help me check the following extensions, is that
OK? thanks! 

[from_pstn] 
exten => _.,1,Answer() 
exten => _.,2,GoTo(Xfer,s,1) 

[Xfer] 
exten => s,1,Background(privacy-prompt) 
exten => _.,1,Dial(SIP/${EXTEN}@$(OutboundProxy), 30) 

Any suggestion? 
I am really not sure that whether $(EXTEN) can refer
to the numbers that entered after prompt? 
Thanks!
