Hi Jesus,

 

For Audio Encryption (SRTP), CWMS uses TLS. As for exact cyphers and key length, this changes from version to version depending on security improvements. What exact version of 2.5 are you running?

As for PC Audio users, externally, they are connecting to the system via port 443 so all the traffic is going via 443. Currently, most common SSL certs issued by Certification Authorities for HTTPS traffic are using 2048-bit encryption.

I hope this is what you wanted to know.
