[cisco-voip] 8832s

Thanks, now I want to watch that movie again.  It's been a looong time.

I can agree that support is not black and white.  Though, do consider the
Cisco Partner's perspective, when Customers ask for recommendations on what
they should be doing.  Our responses should always be motivated by keeping
them on supported combinations of: configurations, hardware, and software.

And back to my original point, having firmware delivered via CUCM upgrades
and Device Packs is hurting that effort, because the collateral upgrading
which is occurring, is seldom what you want.  I.e., Production is not ready
for the new firmware, or it's older than what you are already running.

Case in point: I have a customer right now with ones of thousands of
phones, looking to add support for the Webex Room Kit device, so we need a
Device Pack, but they are not ready to roll out a major firmware upgrade
from 11.x to 12.x on all of their 78/8800 series phones.  Therefore, I have
to now dance around the firmware upgrade, in what should be an otherwise
easy task of applying support for just this specific device model.

I'd be curious to know how many people are actually delivering phone
firmware via Device Packs, versus CUCM upgrades, versus COP files, versus
ZIPs.

For me, it goes like this:

1. CUCM Upgrades are for upgrading CUCM, I typically freeze the existing
phone firmware upgrades (and will do them pre- or post-upgrade of CUCM)
2. Device Packs are for adding support for newer models, I typically freeze
the existing phone firmware upgrades
3. COP Files are almost never used for upgrading phone firmware, they
change the device defaults, when my intention is never to upgrade 100% of a
model right from the start (pilot first)
    *If COPs didn't change device defaults, I'd likely use these over ZIP
files.  Do these restart TFTP automatically?  I cannot recall.
4. ZIP Files are my preferred approach, because they are low risk because I
can easily control their distribution in the environment (like running a
pilot first)
