[Users] MEDIAPROXY - Cannot detect inactive rtp sessions, any other BYE fix method?

Hi Guys, I know that this is not the support channel of mediaproxy, but just hoping that somebody from ag-projects is monitoring this list as well. I found out that, in my case, the SIP-BYE issue is still persistent even by using mediaproxy . If I will stop sending rtp through mediaproxy (eg by killing my client from task manager, or loosing the internet), mediaproxy will still find the session active, like nothing happened and therefore the bill will be inaquarate. I am using the version 1.7.2, and as read in the change log, 1.8.0 didn't change anything on this chapter. Is there any other solution or workarround available? Thxs, Dan
