[Serusers] radius acc: where are the start records?

Hi there after slashing my head with a hammer for a little bit, reading many times the SER RADIUS Howto and acc man page, I managed to get acc to log some RADIUS accounting packets (Stop records and Call Failure records) with FreeRADIUS unfortunately, I could not discover how to generate the START records, no matter what I tried!! as the Stop record doesn't have RADIUS session-time, I need the Start record so my current billing system can be used. I've searched the list archives quite a bit, and googled on [serusers] and FreeRADIUS lists but couldn't find a clue. any help would be gratelly appreciated snippets of ser.cfg [...] loadmodule "/usr/lib/ser/modules/registrar.so" loadmodule "/usr/lib/ser/modules/auth.so" loadmodule "/usr/lib/ser/modules/auth_radius.so" # acc compiled with RADIUS support loadmodule "/usr/lib/ser/modules/acc.so" loadmodule "/usr/lib/ser/modules/nathelper.so" # -- acc params -- modparam("acc", "radius_config", "/etc/radiusclient/radiusclient.conf") modparam("acc", "radius_flag", 1) modparam("acc", "radius_missed_flag", 2) #modparam("acc", "log_level", 1) #modparam("acc", "failed_transactions", 1) #modparam("acc", "report_cancels", 1) #modparam("acc", "report_ack", 1) # -- usrloc params -- modparam("usrloc", "db_mode", 0) # -- auth_radius params -- modparam("auth_radius", "radius_config", "/etc/radiusclient/radiusclient.conf") # -- rr params -- # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) # !!

Nathelper if (uri=~"[@:](192\.168\.|10\.|172\.(1[6-9]|2[0-9]|3[0-1])\.)" && !search("^Route:")){ sl_send_reply("479", "We don't forward to private IP addresses"); break; }; log(1, "LOG: route[1]\n"); setflag(1); # if client or server know to be behind a NAT, enable relay if (isflagset(6)) { force_rtp_proxy(); }; t_on_reply("1"); # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP if (!t_relay()) { sl_reply_error(); }; } onreply_route[1] { if (isflagset(6) && status =~ "(183)|2[0-9][0-9]") { fix_nated_contact(); # CHECK LATER: does this need to be enclosed on # if(method==BYE || method==CANCEL) ??? force_rtp_proxy(); } else if (nat_uac_test("1")) { fix_nated_contact(); }; } # EOF --- one thing that I noticed was that, depending on which side ended the call, the RADIUS Stop packet cames with that side being the calling-station-id and the peer being the called-station-id. is it supposed to be that way?
