Dear Mr. Alen. D Greetings, Million thanks for developing such software to make life easy. i wish to seek your opinion in one task, Kindly advice. What are the possibilities to TOP UP Voucher time / TOP UP a user time. Kindly share the idea. if you in my position, how would you address this challenge? i am asking because you can think better solution than i would. i am willing to study further. *What i am thinking the following, i am not sure even if it is valid thought / idea* Freeradius check accounting records in "Radacct" table. creating additionaltable in radius database *"TOP_UP_TIME"*. When user click top up icon, if something can transfer all accounting records for that user to "TOP_UP_TIME" table. Freeradius would not know since when the user is logged in because there is no account in "Radacct" table. The next accounting that will reach from NAS to Freeradius would be the first time stamp. Thanks / Regards RM --
