[asterisk-users] How to config SIP blind transfer in extension.conf

[Lucian Romi]

I figure it out.
This is because sip_channel is in dialing process. Oh man, how can you do
blind transfer when a call is not establish yet.

so I added

exten => 511,1,Playback(demo-abouttotry)
; Let them know what's going onexten => 500,n,Transfer
exten => 511,n,Dial(SIP/sip_proxy-out)

now it works perfectly well.
