All,

Someone could say a Guide for Configuring Authentication, Integrity, and Encryption in Communications Manager 8.6?

Thanks,

This is covered in the Cisco Unified Communications Manager Security Guide, Release 8.6(1). Feel free to reply with more specific questions after reading the guide.

Jonathan,

I need also encryption between CUCM and SIP Gateways. So, I configured the SIP Gateways only the command "SRTP" globally, and the "SRTP Allowed - When this flag is checked, encrypted TLS needs to be configured in the network to Provide end to end security. Failure to so will expose the keys and Other information." in CUCM.

I do not set encryption for IP phones. When making a call to the PSTN no opening audio. This happened for not IP cphones encryption?

I have some doubts and I could not implement security facilities.

Another question is about the TLS. For SIP Gateways I need to install certificates, right?
