Enable SRTP with CUCM 6.X

Dear Networkers,

We have CUMC 6.1(3) installed and we would like to enable Secure RT¨P for internal Calls.

Can anyone please, provide us with the detailed procdure how to activate such feature? I Checked the "Cisco  CallManager Security Guide" but I couldn't find a clear procedure.

Your help is really appreciated.

Thanks in advance.

Re: Enable SRTP with CUCM 6.X

The decision to perform Encrypted or Authenticated calls is determined by the security profile assigned to each party of a call. The lowest common denominator, including unsecured, wins unless you set mandatory minimums. There is a long and involved prerequisite to doing this where you must enable mixed mode on the UCM cluster using the CTL Client, CAPF, the security tokens, and device LSC enrollment. All of this is documented in the Security Guide that you referenced. The steps involved are far too many to repeat here.
