Well, in websocket module you have the event route that's triggered when a connection is lost [1].

You wouldn't be able to use the unregister function of the registrar module, because a faked SIP message is used to trigger the event, but you can always write a custom SQL to delete the record of the location table using the socket information, to which you do have access: $si, $sp.

Hi,

I'm looking for a mechanism to unregister clients when the corresponding
TCP connection is closed, but had no success so far.

I've tried the handle_lost_tcp parameter of usrloc, but it didn't work:
the user was not unregistered, whereas the connection was seen as
closed by kamailio. Is it still a relevant option?

Otherwise, is there any mechanism that would trigger some kind of
event_route whenever a connection (TCP, TLS, WS, WSS) is lost or
closed?

Cheers,
