Hi Antonio,<br>
<br>
You have to call b2b_init on the initial INVITE that creates the dialog.<br>
And the B2B server will know to correctly treat the REFER when it comes.<br>
That REFER message in fact will never go in the default route but in the<br>
route with the name defined in the module parameter "script_req_route"<br>
