Subject: Whistlephone VOIP Message-ID: <201012070704.CAA10030@ss10.danlan.com> In the past I've bemoaned the fact that external VOIP services do not seem to work well for me. (VOIP within my own network is fine.) Recently I've been using Whistlephone and the quality is quite acceptable; no obvious dropouts. Whistelphone is a free service for calls within the US. It is ad-supported. You listen to a 15(?) second ad at the beginning of your call. You must download their softphone application to sign up; however they do not prohibit (but do not support) use with ATA devices and/or Asterisk. I use it with Asterisk and my ancient 2500 set, so whatever they are doing right does not depend on the client. (I suppose it is possible that they are just closer to me in some sense than other services.) My only worry is that lately the ads have been for Whistelphone itself, suggesting that their funding model may be failing. :( Dan Lanciani ddl@danlan.*com

When your only tool is a hammer, everything looks like a nail. Why would you prefer to have more uninsured drivers on the road? People don't stop driving, just because they lose their insurance, any more than they stop driving when they lose their licenses. Kentucky requires people convicted of DUI to attend "Driving School" (which is really nothing more than a money machine for for-profit school providers). EVERYBODY drives to those classes, and then they drive home afterward. If the insurance company finds out about the DUI, they cancel the standard policy and will only insure the driver in the "Assigned Risk" pool - liability only, for about four times the price. A VERY large percentage of people who get hit with this increase are unable to pay it. So they drive without insurance. The idea behind DUI laws is that people who drive with more than a minuscule amount of alcohol in their bloodstream are inordinately dangerous to other drivers. So why, exactly, does Public Policy ensure that a large number of those presumably more-dangerous drivers have no automobile insurance? ObTelecom: Substitute "Talking on cell phone while driving" for "DUI".

Subject: Question about an old scrambler phone Message-ID: <AANLkTikNo4yk3iRENuKp_f4QRTgnedkZuknL1PEFju-E@mail.gmail.com> (moderator please change my email address so spammers can't use it.) I've got an odd sort of a question for your group. When I was a kid, my friend's dad had a phone in his house that he told me was a "scrambler". It was a regular telephone, mounted on a metal base, with an AC cord for the base. The base had just two vacuum tubes in it, and a couple of transformers. It didn't look like much, but my friend said his dad used it to make scrambled phone calls to his reserve unit. Has anyone ever seen anything like that? I never knew if he was yanking my chain or not.

Subject: Another odd question Message-ID: <20101208010810.GB3356@telecom.csail.mit.edu> This seems to be a day for odd questions, and I just thought of one. The Ethernet plugs we use at work are wired for the "568B" standard, with the orange wires on pins 1 and 2, and the green wires on pins 3 and 6. Here's the question: _why_? I've been told that the whole idea with Ethernet is to avoid "Near end crosstalk", so it seems to me that the best way to do that would be to put one pair on pins one and two, and the other on pairs seven and eight. How did we wind up with 568B? Bill -- Bill Horne (Filter QRM for direct replies)

Subject: A question about CO wiring Message-ID: <E1PQ8me-0001Il-CM@telecom.csail.mit.edu> I've been working for a company that sells a line-switching device for use by the utility industry. We routinely get boxes returned to us that have been fried by voltage spikes, and it occurs to me that a central office must take a lot of surges, spikes, etc. That's a paradox, because I never heard of a CO being damaged by anything but a direct lightning hit the whole time I was a tech. We had, of course, "carbons" and "heat coils" at the frame that were intended to take care of spikes coming in on the cable, but to gauge by the way today's electronic boxes get burned up so easily, I'm really surprised we didn't have a lot more trouble with lightning. Ergo, I'm wondering what other equipment was used to keep the CO's from suffering at Zeus' hands. Bill -- Bill Horne (Filter QRM for direct replies)
