I believe that the original text is correct. The intent is that repeated
setup attempts are delayed at least by 15 seconds and up to a maximum delay
that's at least 2 minutes (the actual maximum is at the discretion of the
implementation).

I agree with Stewart that this is outside an errata scope, and requires a
consensus RFC if a change is warranted.

I've updated Ina's email address. I also removed Bob's old email address,
as he's left Cisco and I don't have an updated address for him.

Cheers,
Andy
