<div>I want to setup a blind transer for auto forwarding to SIP peer.</div>
<div> </div>
<div>I have context forwarding looks like this in extension.conf</div>
<div> </div>
<div>[forwarding]</div>
<div>...</div>
<div>exten => 511,1,Dial(SIP/sip_proxy-out)<br>...</div>
<div> </div>
<div>This will do the re-invite, which is attendance transfer maybe. </div>
<div>But I want a blind transfer by REFER method. How can I do that?</div>
<div>I know that the transfer() function may be able to do that. But I don't </div>
<div>know the syntax for that. </div>
<div>I tried</div>
<div>"</div>
<div>exten => 511,1,Transfer(SIP/sip_proxy-out)<br>"</div>
<div> </div>
<div>So can any one give me a hint on this? Thanks!</div>
