[cisco-voip] 8832s

I can't believe there's still no syncing of TFTP/MOH Files or at least
making it the default option.  Uploading things to every node
over-complicates things.  And TFTP File Management has no bulk upload which
is super annoying when I rebuild subscribers on an upgrade.  I keep meaning
to make a script for that bulk TFTP upload.

There definitely needs to be some overhaul of phone firmware management.

We'll probably just see the phones start reaching out to the Webex cloud
nightly to update their phone firmware as we further this cloud transition.

We have to make sure this stuff doesn't get too easy for the customers and
kill off all our jobs too :P
