Are you sure that removing such registrations is the best thing to do?
You don't know what the user is going to do; maybe they will be using it
continuously, or maybe it'll be backgrounded. It's impossible to
determine, so you can't assume any given registration is stale, and it
is reasonable to attempt to contact the registrant for any given inbound
call, even if the attempt is futile because it has gone unreachable.
Meanwhile, the moment the endpoint is "woken up" via a push
notification, it will re-register and overwrite the stale contact
binding instead of adding an additional one, provided that the match
mode is set correctly.
