Does anyone know if you can encrypt media and signaling to the provider but not to the endpoint? I am connecting to Twilio, an internet sip trunk provider and they support SIP TLS and SRTP. Behind the cube I am running CUCM and all my phones are not encrypting neither signaling nor media. To keep things simple but secure I want to just encrypt the cube to provider leg. Is this possible? If someone knows for sure it’s not and why, it would save me a ton of time.
