As stated in the draft:

   Once a session is setup ICE consent freshness [RFC7675
<https://datatracker.ietf.org/doc/html/rfc7675>] will be used
   to detect abrupt disconnection and DTLS teardown for session
   termination by either side.


Which means that the server has to monitor the ICE requests and
timeout any client which hasn't issued a new ICE request to renovate
the consent in 30s.


Best regards

Sergio
