[Serusers] Transparent SER (only) for accounting

Hi Guys, can i use SER in a transparent mode like a squid, with a iproute-redirect? My user currently using an asterisk for incoming and outgoint calls, but i need to do an accounting of every call (call-lenght) on the firewall, is this possible with SER, including some kind of "pass-through" authentication/registration to asterisk? I don't have direct controll over the "backend", so it's not possible to setup the users on SER... If someone has already done something like this i would really appreciate a ser.conf as a template :-) Regards, Andreas. _________________________________________________________________ Watch movie trailers online with the Xtra Broadband Channel http://xtra.co.nz/broadband
