Hello, I 've just came to the point of rolling my own billing that I have mysql database with table "acc" and details of called party , accstart, acc period and so on. I have another table that I have prefixes and prices for T1,T2,T3 . My question is : do You have some howtos, scripts for rating users? I try bash for now but it is slow and not scalable in future.. what about mysql shell or sth? Could you send me some examples ? I would appreciate that Regards..... -- Pozdrawiam, Wojciech Ziniewicz Optocomp sp.z.o.o, www.optocomp.pl mailto: wojtekz(a)optocomp.pl +48(0)691031535
