configuring phones and CUCM for SRTP

Hi All,

I am trying to find a way to configure Cisco IP phones to register with secure-SIP to CUCM and to use SRTP for media traffic. I found only one way to do so, which includes purchasing tokens from Cisco to generate CTL certificate and change the cluster security mode to mixed mode.

like the article below:

https://supportforums.cisco.com/document/73611/ip-phone-security-and-ctl-certificate-trust-list

I was wondering if there is another way to do so, without the tokens, like using a centralized CA server for the new certificates.

If you have 10.0(1) or higher, you don't need the tokens. Otherwise you do need them.
