I believe you have a polarity reversal in your reading of my post. VoN is a subset of VoIP; it is what providers who *advertise* VoIP are generally actually selling; it is much more prone to problems on the local IP loop and the backbone than the subset of VoIP which the cable company who's selling you the broadband is offering. > > Cable companies are selling you *one hop* (maybe 2 or 3; certainly > > not > > 12-18), over a link with bandwidth protected from whatever may be > > going on on the Internet IP link they're also selling you; and which > > is > > therefore guaranteed to have better quality than whatever "VoIP" > > service > > it might be competing with." > > > > Better? > > Not really, because you're still arguing a point that doesn't matter. > Is it Voice?

SMTP isn't latency, jitter, and dropped-packet sensitive and SIP/RTP is, and that's pretty obvious. Yes, the number of hops and exchange points matters to VoIP in ways that it doesn't matter to SMTP and POP. I will attempt, one more time, to clarify my original underlying point. Then, if you absolutely insist, I shall give up: """ Lots of people sell PSTN gateway access via the TCP/IP public Internet. Nearly all of them call this VoIP. It is, but that term is insufficiently specific to allow the comparison of this service with "VoIP" service offered as a "triple-play" by broadband/cable companies, because their service is "protected" in one fashion or another from many impairments which the service sold by those third-parties is prone to, by the nature of the differences in their transport. Additionally, characterizing that third-party service solely as "VoIP" tends to give that term a bad reputation in other contexts, such as protected internal VoIP PBX service, in which it's perfectly suitable, even though Vonage is generally no better than mediocre. """ Did that more clearly explain why I'm unhappy with the fast and loose usage of the term VoIP in many contexts? Cheers, -- jra
