But no UDP, right? It's what I wanted to know in order to see what kind of patterns can be applied, given that the UDP is connectionless.
For TCP/TLS, what can work, it's to use tcpops module which can execute an event route when a tcp/tls connection is dropped. If you track the association of connection id with the call-id of the presence publish, then you may be able to do some tricks and lower the expires of the published presence state. I haven't had the time to see what's possible there, but could worth investing. An alternative would be to enhance presence module to behave as registrar/usrloc (which can delete contact records on connection drop) to expire documents when tcp/tls connection is closed (not sure if anyone already added it). Btw, it's your client (I mean, can you control its development/features), or it is just some generic sip softphone? Because there can be some tricks added to the client side as well if you control it.
