[cisco-voip] Migrating from CUCM 7.1.3 to CUCM 8.6.2

[Ted Nugent]

We've proposed "drive to 9.x" to many customers recently and the biggest
argument against this that we've hit was that most of our clients are
running 79x0 phones which will not be supported, all of these clients
budgeted for the upgrade, UCS and professional services but not the phones,
even with incentives from Cisco this has been a giant hurdle. Most have
decided to stop at 8.6 and will budget for phones next year.
