Is there anybody on the list who experienced the same problem or at least confirm that I'm on the right track with my analyzes below. Thanks, Arsen.

Environment: Sofia-SIP-1.12.10 is used as a typical UAS with TCP as SIP transport on Windows. Problem description: Accepted socket remains in CLOSE_WAIT state. How to reproduce: UAC connects to Sofia-SIP UAS, makes basic call and finally tears down TCP connection. Tport output: // Windows tport_wakeup(00CB7310): events HUP tport(00CB7310) tport(00CB7310, 0) tport_set_events(00CB7310): events tport(00CB7310): set timer at 1797891 ms because idle since send // Linux tport_wakeup(0x9cf91e8): events IN tport_recv_event(0x9cf91e8) tport_shutdown0(0x9cf91e8, 2) tport_close(0x9cf91e8): tcp/x.x.x.x:3095/sip tport(0x9cf91e8): set timer at 0 ms because zap When remote UAC tears down TCP connection 'events HUP' is raised on Windows, while 'events IN' on Linux. If I modify Sofia's code to raise 'events IN' in case of Windows too, socket is closed. The other workaround is to modify tport_hup_event handler isntead of < tport_shutdown0(self, 0); use > tport_shutdown0(self, 2); Any inside thoughts would be really helpful. Thanks, Arsen.
