Let's work on a description on the logic needed and see if Vitally's code is close:
1. Connection dies (tcp, tls, sctp) 2. Event-route activates 3. Check if there's a outbound flow with reg-id associated with the flow 4. If not, is there a registration associated with the flow 5. If 3 or 4 is true, do something
Do we have functions for 3 and 4? Can this be done in scripting?

I started to implement this. It is in a branch somewhere, but I couldn't get it working.
If someone who knows the TCP code better could take a look...
Regards,

Hello,
I've made a patch to kamailio-4.0.3 which removes stale registration when kamailio looses an incoming tcp connection. Of course this patch needs more work.
Since the are no direct references between user location contacts and tcp connections callback function uses linear search through the whole location table using received field as a key.
Can anybody more experienced in kamailio internals check if I chose the right place to get information about lost tcp connections ? Another thing I wanted to ask is maybe somebody can suggest a better way to tie a tcp connection to the user location information without complicating "usrloc" module by any heavy data structures.
If anybody else except me need this It would be great to fix known problems and add it to kamailio. <remove_tcp_contacts.patch>_______________________________________________
This is something required for outbound too. We need to remove the registration and thus the flow if a connection dies. The problem is that we can manage the connection on another server (edge proxy) too.
...which is why I earlier proposed an event-route for this use-case.
