[sr-dev] executing tm:branch-failure event_route also when t_relay() fails?

if t_relay() fails, for example, when tcp connection to destination is dead, no transaction is created and therefore tm:branch-failure event_route thus is not executed. this greatly complicates config script writing, for example, when trying to unregister unresponsive contacts. is there any possibility to enhance the current t_relay implementation so that even if transaction is not created, tm:branch-failure would still be executed for each branch of the failing t_relay? -- juha
