Hi, I'm recently added voip on our services using ser. i bill my users using the time of INVITE and BYE. but got a complain from one of my users, why even if the call was not answered they still get billed, what can i use on ser to check whether a call has been answered or not, then i will bill only base on the answered call. Thanks in advanced. Regards, Ron _______________________________________________ Serusers mailing list Serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers
