Karl,

The paragraph to which you refer seems to me to say "the endpoint may choose
to terminate the call as described in Phase E, or it may attempt to
re-establish the Call Signalling Channel as described above.".  This is a
lot more explicit than "the procedures described above shall be used" - it
says, in fact that an endpoint may follow either of the courses of action
you describe.  A gatekeeper, however, would appear to be obliged to do the
first: I wonder how many do!

Regards,
Chris
