I was testing a scenario whith parallel forking (multiple registers) where 2
endpoints answer near simultaniously. When phone that was just a bit slower
hangs up, the BYE gets forwarded to the caller and thus the connection is
terminated. This is as far as I know for stateful transactions (t_relay())
I always assumed in this scenario the state machine in kamailio would prevent
this kind of behavior by itself. Is there a way to prevent these messages
being forwarded?
