change cluster security mode for call encryption

[@Syed]

Dear All,

I am planning to change cluster security mode from non-secure-mode to mixed-mode to enable call encryption, but before making any changes is there an option for me to test this on a few phones.

Testing this as part of proof of concept

A quick reply will be appreciated

before you do that, make sure your cucm software is restricted and not unrestricted,

you might also want to consider running IPSEC to your gateways

Hi Dennis,

It is an unrestricted version.

I did not get this point, can you elaborate on this.

you might also want to consider running IPSEC to your gateways

Are you saying that I can test a few phones, how??
