From the blog post: 'Today my wife received a phone call from a Comcast representative who had called to promote their new "Comcast Digital Voice" service... Ordinarily, we don't mind Comcast calling us from time to time with new offers... [but this time] they proceeded to tell LIE after LIE in an attempt to convince us that Vonage was not as good as Comcast Digital Voice. Imagine how many people would be scared into using Comcast Digital Voice because Comcast makes them believe that Vonage is insecure and only works when your PC is turned on.' Is Comcast going a bit far in their techniques to lure in new customers?"

Actually it's slightly more secure only because SS7 is a simple protocol compared to SIP (tunneled of course). It's also more secure in that a non-authorized person (like a private investigator) could not tap a VoIP connection without gaining entry to the premises. A POTS connection can be tapped by anybody who can access your line (anywhere). Comcast's VoIP likely uses similar technology to Vonage and so is probably just as secure.
Define "secure"? POTS/DSL/Vonage-on-DSL has an inherent level of security and reliability above cable/cable-VoIP/vonage-on-cable because telco technology is [b]circuit based[/b]. Your line isn't dependant on a shared RF medium that can potently be snooped/jammed/interfered with by anybody else on the same node. Doubt that? Then explain why it took Time Warner six months to figure out that the problem with my Roadrunner service was a friggen 45 year old TV down the block leaking RF onto the cable plant? Had I TW's digital phone/vonage I would have been royally screwed. I can't recall the last time that my POTS/DSL service was taken down by a 45 year old phone next door....
Anybody that relies on VoIP service over a cable connection is insane. My DSL service is circuit based and survives just about anything including power outages. My cable service doesn't even survive thunderstorms and dies during power outages, presumably because the repeaters aren't line powered.

DSL is a bit of a challenge, too. However, DSL can be monitored from other pairs in the same trunk just like a cable modem. (listen for weak cross-talk.) The DSL physical layer isn't scrambled at all, so if you can see the signal (no matter how weak), it can be decoded with ease.
The PSTN ceased to be truly circuit switched decades ago. It's been digitized, packet switching for a long time. The only circuit is in the "last mile" from the CO to CPE. And more often than not these days, your copper wires don't even go all the way back to the CO; they go to a multiplexer. (or "remote DSLAM" if we're talking DSL.)
As to which is "secure"... neither. POTS/DSL is easiest to sniff if you're willing to sneak around to plant a physical tap -- on the NID or any of the boxes on down the line, right down to breaking into the DSLAM itself. Cable just requires you be somewhere in the neighborhood (no sneaking required), and willing to sift through a lot of noise to find one specific modem's traffic.
On the issue of power, both DSL and cable are endpoint powered. If your house loses power, your modem will stop working. It doesn't matter if it's a DSL modem or a Cable modem. Telco's may have more experience with keeping their equipment powered, but they aren't going to give a shit if the DSLAM loses power during a storm; they'll only care about keeping "lifeline" services (read: POTS) functional. That DSLAM in the cabinet at the top of the hill doesn't have a generator backing it up.

On a more serious note, I've talked to many customer service reps who didn't know what they are talking about. I don't know that you can call it lying, it is perfectly possible this guy thought these things were true. Or maybe this guy is just a jerk who will be in the unemployment lines in a few weeks (every company has these, probably even Vonage). Bottom line is, you can't trust someone who calls you up during dinner to try to sell you a product. Just as you can't trust a single blogger that claims Comcast is running a massive campaign of disinformation because of a single experience.

Hate to say it by Comcast is partially correct (Score:5, Informative)
They are selling a full DQOS phone service. This means that that there is full QOS when on their network. You are guaranteed that you will have the bandwidth for the telephone call. This cannot be said when you are using Vonage. Vonage over a DOCSIS connection is strictly best effort, meaning that you voice packets have no more priority on the line than you neighbors downloads. This will (if it does not already) mean that you will have inferior quality on a Vonage phone vs. the Comcast solution. Also with DQOS from Comcast you get priority for any 911 call. You cannot get this from Vonage.
Disclosure - I do work in the cable industry but for a equipment vendor not Comcast.

DOCSIS has excellent QoS support. It supports what are called "Service Flows" when the modem is provisioned in DOCSIS 1.1 mode. Essentially, a service flow creates a secondary pipe to the CMTS that is completely independant of the other ones. Thus, there would be a second service flow, provisioned for 64 or 128Kbps, used only for VoIP, which has a higher priority than the data flow.
When using cable modem service, traffic from Vonage unfortunately falls into the "data" pipe, and therefore gets jumbled with the rest.
I don't feel that Comcast is being anti-competitive at all, they're using a feature of the DOCSIS specification that cable operators devised and use. Perhaps you need to take your case to CableLabs (and get laughed out by them).

Verizon is also not trying to play nice either. They only want to offer good deals if you buy bundled services. This is business in the USA.
The whole argument about security is false, misleading, and only made to confuse customers... trouble is the media gets confused too.
It doesn't matter what voice service you use, it is susceptible to interception, end of story. The only thing that you can hope to do is make it more difficult to intercept it. Military grade encryption end-to-end is not available, and the US government won't allow it to be used anyway if they can at all prevent its use. (think of the children, or think of the terrorists) So the argument about which VoIP service is secure is a totally mute point.

When the service guy arrived, he told me that the line splitter on the street was not only corroded but had been installed backward. Not sure how that's possible, but there it is.

Whenever a customer calls complaining about voice quality, it's almost always latency or some other issue with their connection; VoIP is, as you can guess, very sensitive to connection quality.
Comcast has been one of the worst for us, though other cable providers aren't much better (Time Warner, I'm looking in your direction). I cannot prove it, but I'm certain Comcast is doing some sort of traffic shaping for VoIP packets not their own, and it wreaks havoc with my company and many others, because we can't do anything for the customer except tell them "take it up with your ISP".
I think we all know what the ISP's invariable reaction is. Some tier-one flunky goes "Yup, signal looks good! No problems here!" and the customer comes back to us and there's nothing we can do about it. It doesn't matter how many pingtests, traceroutes, or other measures you offer them -- the cable companies have been notoriously unhelpful in getting their act together. Worse still they'll offer outlandish suggestions to the user, like "getting a static IP might help" or "upgrade your connection to six megs", neither of which will do a damn thing (well, the latter might, but it's not likely that bandwidth is the problem).
Now I admit that part of this is that VoIP over public residential/business connections is purely "best effort", especially the RTP stream is delivered via UDP which most ISPs and backbone providers consider less important than TCP. Contrawise, Comcast and other integrated providers can QoS their own VoIP packets any way they like. But for an ISP to leverage this fact to spread misinformation or misrepresent what is actually going on is totally ridiculous.
Part of the problem is that most people really don't know anything about computers or the internet. They'll tell you "but I have a fast connection! It's three megs!" because they don't understand the difference between latency and bandwidth, or they'll point out that their email and websites load really quickly. From this end-user's point of view there's nothing wrong with their connection that should cause their VoIP phone to suck, because "everything else works", and I partially agree with them -- they shouldn't have to constantly harrass their ISP to stop screwing around. (My disagreement is my cynicism of caveat emptor, and it wouldn't kill people to know a little something about how the service works, at the very least so they know to whom to complain when something goes wrong. In essence they're bringing a car to the mechanic complaining that the ride is bumpy, when the problem is the road outside their house is full of potholes.)
But even my cynicism has limits -- as a matter of fact I had to go through this same crap with my home cable provider, Charter, and it took nearly two weeks for me to get them to deal with the problem. Keep in mind that's someone like me, who knows what he's talking about, who is in IT, who can provide useful information about where the problem lies, and knows to whom to speak and how to phrase the problem to get results. What is your average user supposed to do, when they don't know anything about this stuff?
When it gets to that point, and the ISP is telling them things like "reboot the computer!", the user sees only a few choices -- get a new ISP, or get a new VoIP provider. And here comes Mr Comcast Droid with his promises of high quality, one bill, blah blah blah, and the user thinks that sounds pretty good, so they make the switch.
Also, for those of you griping about security of VoIP, I get that question a lot too. It's not particularly secure, but I find it amusing that nobody asks that question when they're getting a copper line from the local Bell, which isn't secure either. At least to eavesdrop on VoIP you'd have to have access to one of the routers along the path, whereas any ten-year-old can plug a handset into the phone interface on the outside of your house (my friends and I did it all the time to bug my sister).
