I would agree. While we were going through the migration phase there was a
strong Cisco presence. Unfortunately, we've seen that presence wane now that we
are fully deployed. Unless of course, we start talking about buying a new
product... ;)
We've picked up quite a bit of experience from the migration, so our requests
now have become quite a bit more complicated and are more design related, which
may be at the root of the problem, however, sometimes, we just need a pointer in
the right direction.
We've (or I've) been getting much of that from this list where I once got that
from our SE team pointing us to different internal Cisco resources via
conference call, etc.
I like reading documentation like everyone, and expect that I have to do my
part, but a half hour discussion with a knowledgable rep can give you a
headstart that no documentation can.
