Sip droid will know the local network is down and be able to hang up the call because of that. FreeSWITCH has no such knowledge, so won't know the call is hung up and will continue sending RTP. 3 possibilities are:1) Use session timers2) There is a parameter to hang up a call is no RTP has been received for a certain period of time3) Use SIP/TCP, keepalives might help (but the default is measured in hours) Note that all of these are timeouts - you simply won't be able to know the call has ended immediately.
