Just wondered if anyone has done or is doing a radius app ? There are several ways to deal with radius stuff. Straight auth checking & for those with calling card applications stop and start recording. Even the situation of restricting to one call at a time could be done so theft of time doesn't occur. basically.. send to radiusauth(variable1,variable2) retunrs auth (yes/no) send to radiusstart(variable1,variable2) returns auth yes/no returns number of minutes (being number of minutes or charge units left) send to radiusstop(variable1,variable3) variable1 = session-id (identifying user) variable3 = number of units used Gary .
