I am currently using UM as our radius controller.
When a client logs on using a 1 hr voucher, their 1 hr starts from the time of first logon.
When they disconnect, usermanager still sees the voucher as active and after 1 hr, the voucher has expired.
Is it possible that a client can purchase a 1 hr voucher, use only 10 minutes and log off. When they return in a few hours, and log on, there will be 50 minutes remaining on their voucher.
Basically, 1 hr voucher can be used for 1 hr usage and not from the time they log on.
