[Serusers] Accounting forwarded calls with Setflag

Hi I was wondering if anybody had some advice on howto account forwarded calls to the subscriber who farwarded his phone? ATM I account people by the From address, and I was thinking of adding a control prior to the routes in ser.cfg, which serched the message for any diversion header: if (method=="INVITE" & search("Diversion:")) { log(1, "Call is being forwarded and we need to account it to this person\n"); append_hf("P-hint: Call being forwarded from\r\n"); setflag(1); }; But I dont seem to be getting the information, that I seek, cause no 302 status gets recorded in my accouonting table. Any help on what I'm doing wrong? And is there a better way to use setflag, or more correct? Regards Martin
