Hi everybody,
Background
Video endpoint ---- CUCM --- EXP-C ---(tls)--- EXP-E (CompanyA) === Internet === (CompanyB) video endpoint
Due to the scenario is connecting to other company, so
> Expressway MRA with B2B is used
Question:
My question is how do I know the path between Exp-E and CompanyB's Video Endpoint has encrypted media stream?
In my understand, encrypted connection usually required to generate CSR and apply signed cert between 2 nodes
However, I don't see the Cisco Doc has mentioned anything about the cert setting between CompanyA and CompanyB.
Or is it already encrypted between Exp-C and Exp-E, then the rest of packets are all encrypted toward CompanyB?
Does anybody has an idea?
Thanks in advance
Sam

Hello,
You are right it is encrypted via SRTP at the beginning of CUCM.
You can read the first few pages for answer.

If both organizations support encryption, the call will be encrypted end-to-end. However, if something within the path doesn't support encryption, the call will not be encrypted. In either case, the call details should tell you if it's encrypted or not.
