[OpenSIPS-Users] B2BUA Ripping/Truncating Callid

[Logan]

This is the extent of my local route. If the $var is not present, I do not add it. Do you see any issue with what I'm doing here?


local_route {
        #xlog("L_INFO","***** IN LOCAL ROUTE ********\n");

        if (is_method("INVITE")) {
                if($var(pai_userpart)) {
                        append_hf("P-Asserted-Identity: \"$var(pai_display)\" <sip:$var(pai_userpart)@$Ri>\r\n");
                }else{
                        xlog("L_INFO","PAI is not present, not adding\n");
                }
        }


}

You need to be careful when you alter requests in B2B mode (the
received INVITE and the sent INVITE belong to different transactions).
Make sure that you have something valid in those vars before applying
any changes to the outgoing message.
