I'll need to check the old e-mails.

But, assuming we did NOT agree on that, are you saying that within an
existing subscribe dialog (containing one ore more subscribe usages, it
is ok to send an "initial" INVITE, containing a From AND To header tag
(isn't that considered to be a re-INVITE?), and create an invite usage?
