This is why the SIP timers were introduced in the first place: there is no correct way to detect when the client is going away, as no activity is a good session state.That's only true when Asterisk tells the other endpoint that it is allowed to use voice activity detection and silence suppression, which at this point it does not do. In spite of that, there are many endpointsthat do it anyway,
Oh yes, I've seen these problems first person, mostly manifesting themselves as dropped syllables after a period of silence if not complete loss of a call, but I assumed it was not a negotiated option but rather left to unilateral decision of an endpoint. Thank you for the correction!
