I came across this post from January 1st of 2011, and I'm republishing
it, since I'd like to see more discussion on this topic. John Levine
answered Sam with some detail, and I'll add some more questions to
John's original post, but VoIP remains a "Black Box" to me and so I'm
seeking some more info.

I'd add a couple of questions to Sam's original:

1. Why is Comcast's "VoIP" offering so bad? It's got reserved
   bandwidth, a fatter pipe, and the advantage of a closed system that
   has known, well-documented interfaces at both ends. What went
   wrong?

2. What did the "1995 Caller ID decision" involve? Was it ever resolved?

Happy New Year, Bill.

I would be especially eager to learn how Vonage really works.  It's all a 
mystery to me.  Sure, I undersand the transmission method, but I don't  
have a clue about how they "switch" calls and how they interface into the 
PSTN.  I recall the suits where Verizon (I believe) seriously challenged 
Vonage for a time, based on Vonage's violation of Verizon patents, or 
something like that.

Clearing the air on Vonage and VoIP would be great.

Another interesting subject would be the history of how strong the FCC was 
in the 1995 Caller ID decision, then in subsequent years have seem to lost 
interest in maintaining the integrity of Caller ID delivery and they never 
did address the reserved PBX component of the original decision.
