True. After looking at it again, A and B are the only answers that mention "endpoints"
• (test) A. An Expressway-C communicates with the internal endpoint and forwards the media to and from an Expressway-E. (most logical)
• B. A Cisco Endpoint is configured with a publicly routable static NAT SIP address to advertise instead of is private IP address. (best answer)
• C. An Expressway-C communicates directly with the remote party using the ICE protocol (not an endpoint)
• (test) D. An Expressway-E is used as a VPN server to allow remote SIP edge servers to connect calls (cannot find any info on this) (not an endpoint)
• E. An Expressway-C rewrites the SIP SDP to advertise its own IP address to the external party. (not an endpoint)
Having a hard time with this one.
Answer A is a given.
I have found zero information that suggests Expressway-E being used as a VPN server, but it can be used as a TURN server which possibly debunks Answer C because with ICE, the Exp-C removes itself from the media path.
Now with ICE, the TURN server allocates relays and one of the paths for sending/receiving media is via it's publicly-accessible address on the NAT device
