[OpenSIPS-Users] b2b refer scenario

[Duane Larson]

One thing that might be asked of you is what version of OpenSIPS are you
running.  I think there have been some updates that fixed some b2b issues.
Also I believe that  in order for you to use b2b the SIP message cannot have
a ToTag.

You have to use B2B like so

 if(is_method("INVITE") && !(src_ip == "OPENSIPS_IP") && !has_totag() ) {
{
    location();
    b2b_init_request("refer");
    exit;
}
