Now you did it - asked for an answer - and I just have to take the bait!!
1. Realize that SIP and RTP can have two different paths. The SIP can be routed to GC directly and the RTP can transverse a different path depending on STUN and TURN replies. AWS Direct Connect is like a pipe that rides the internet in its own little tunnel and only allows connections to AWS end points. So, if you have Direct Connect any traffic to GC can go through that connection and avoid any contention on the Internet because it is controlled by AWS and only allows AWS traffic to flow through that tunnel - kind of like a toll road - you pay to have a fast lane that is not affected by anything happening on the normal lanes. (I am from LA, so I understand fully the need for toll roads).
2. Think of Direct Connect like the entrances to the toll roads - you can just hop on any place. Your AWS Direct Connect partner will bring you an MPLS that allows you to "hop on" to Direct Connect from you facility by either a dedicated on ramp or riding over your existing internet connection to the local handoff to AWS, so you will pay your carrier for this local access loop and then pay AWS for Direct Connect.
Now as for your questions about privatization of the Edges (if I can refer to it like that), GC only supports AWS Direct Connect on the public side of AWS. If you use the Private side, you can have your traffic flow into AWS into your own VPC and then use a VPC gateway in AWS to transverse over to the public side and into GC, but you cannot connect directly to GC on the private side like an MPLS connection to your VPC or data center.
The Edges themselves create their own little tunnel to GC through your firewall on port 443 and use RTP ports to transport audio to and from GC in the cloud. Cloud Front is not really involved in any of this except for storage of resources like icons, wavefiles, and the like.
I hope I have not confused things too much and happy to get into some details if need be.
