Please note this is non-normative text and I would not interpret the above as a valid argument. Moreover, OPTIONS timeout has no effect on the dialog or its usages (see RFC5057). _______________________________________________ And very commonly, a timeout (408 response) indicates a *temporary* unreachability, and the UA should not assume that the dialog is unusable forever.
