• AWS's WebRTC best-practices text tells customers to allow-list incoming UDP traffic on port 3478, while the networking page lists 3478 only as an outbound rule and says no inbound client port is needed. disputed in context
• AWS strongly recommends that CCP media between the agent workstation and AWS go directly, without traversing VPNs or network accelerator hops. in context
• The Amazon Connect CCP sends its SDP offer, including host, STUN-derived and TURN relay candidates, to Amazon Connect over a WebSocket signaling channel, and receives the SDP answer the same way. in context
• Because standard WebRTC leaves signaling to the application, each CCaaS browser agent client uses its vendor's own signaling to its cloud (AWS documents a WebSocket channel); none of the fetched vendor pages say their browser client uses SIP over WebSocket. inferred in context
