[cisco-voip] Phone authentication

[Reto Gassmann]

Hello

We have to setup phone authentication for all of our 4000 IP Phones (7960,
7961).
We currently run our Callmanager 4.2(3) without authentication and encryption.

Has any one some kind of best practice on how to set this up. Especially the
deployment for the phones would be interesting. Te set up for the CallManger,
the Certificates and the key pairs for the phones is pretty good described from
Cisco.

Thanks for input
