That seems wrong - I would have thought it was a "prerequisite" as
opposed to "the same thing" because seizing the line is immediately
followed by a dialing request.
This requirement is about sending one request that causes both actions
to occur. In a PSTN ringdown circuit (a very specialized circuit,
used for "hotlines"), the two operations are the same thing. Besides
this statement, is REQ-16 itself not clear? Perhaps I should just
remove this statement if it adds confusion rather than clarity to the
requirement.
IMHO, a good fix is:
REQ-16 The mechanism should support a way for a UA to seize a
particular appearance number and also send the request at the same
time. This is needed when an automatic ringdown feature (a telephone
configured to immediately dial a phone number when it goes off hook)
is combined with shared appearances - in this case, seizing the line
is >>>integrated with<<< dialing.
