With an extensive collection of 500 hot Ringback Tones, Universal Music Group is the newest resource for Verizon Wireless customers looking for the perfect Ringback Tone to replace the standard ring callers hear while they wait for their call to be answered. Verizon Wireless became the first national carrier to offer Ringback Tones when it introduced the service in Southern California and Sacramento last year. With an entire catalog of popular music choices, Universal Music Group makes it easy for Verizon Wireless customers to select the Ringback Tone that best fits their personal style. By browsing through categories such as Rap, Hip-Hop, Soundtracks, Metal/Alternative, R&B/Soul, 80's, Classic Rock, Pop/Rock, Country, Club Hits, 70's, Oldies, 60's and Holiday, customers can set up their Ringback Tones to include a standard Ringback Tone (including the Verizon Wireless standard Ringback Tone), or choose different Ringback Tones for each caller based on the Caller ID, Group List or the time of day. Universal Music Group fans will find it easy to choose the perfect Ringback Tone by simply visiting the Ringback Tones Web site at http://www.verizonwireless.com/getitnow/ringbacktones where they can register, browse and preview the latest Ringback Tones from the biggest names in the music industry today. Customers can also sign up to receive a TXT Alert whenever their selected artists release new Ringback Tones by visiting the My Alerts section of the site and selecting TXT notifications. Standard text messaging rates apply to TXT Alerts. - http://finance.lycos.com/home/news/story.asp?story=48430368 ------------------------------ From: email@example.com Subject: VOIP Cautions Date: 18 Apr 2005 10:13:26 -0700 1010news radio reported that consumers need to be careful before signing up for VOIP service.

All kinds of mischief is possible: A rival might try to capture your business sales lead. Or a snoop might listen in on a neighbor's secret calls to a lover. Though these attacks would be difficult to perform today, security experts believe that as such phones get more popular, hackers will have greater incentive to develop tools for automating such attacks - just as they have with viruses and other computer threats today. As for reliability, phone providers are still trying to make their systems fully compatible with 911. In some cases, phones might ring a non-emergency number or fail to provide caller ID details like location - crucial when a caller can't speak. And during blackouts, traditional phones can draw upon electricity in the phone lines, but an Internet modem will fail without backup power." ------------------------------ From: firstname.lastname@example.org Subject: Journalist Seeking Source, Mobile Phone Cracker or Related Expert Date: 18 Apr 2005 08:05:30 -0700 Following the Paris Hilton Sidekick II story, I am writing about how to "hack" (in a good way) your own mobile phone in order to make it more secure.

Hendricks <email@example.com> Subject: SprintPCS Lousy Web Interface Date: 18 Apr 2005 10:14:34 -0700 Organization: http://groups.google.com Ok, so I received a fraudulent call on my SprintPCS phone this weekend. Someone claiming to be a SBC Representative and stating that I have an account balance due of $117 and I can pay now with check or credit. I quickly hung up and called SBC, who confirmed this was not the case and that they did not make the call. Being a good citizen, I'd like to report the fraud incident with the phone number. Unfortunately, the caller ID was blocked on my Sprint phone. I called Sprint to get the number, but they said my billing cycle ended yesterday (a day after I received the call) and that they could not pull up calling history from that period (!!). She said I could either wait for my invoice in the mail or look it up online. Not wanting to wait for snail mail to report a phone number that will likely disappear in days, I tried to go online to check where the call originated from. Their MyPCS is an UNHOLY PILE OF HORSE MANURE. It's quite possibly the slowest interface I've ever used, taking ~10 minutes to load each page. Before I can get to my latest invoice, it usually times out and requires me to login again, and I get to start all over. I've been trying for hours to view my damn invoice online. It's good to know that Sprint cares so much about fraud prevention. Why is it so terribly difficult to find out who called me?

Different _types_ of batteries require different kinds of re-charging circuitry. Using "type b" batteries in a "type a" charger -- *whatever* 'a' and 'b' are, is asking for trouble, unless you know enough about the charger circuitry to _know_ that it is not going to be a problem. Some chargers have 'smarts' enough to handle mixed types of batteries, many others *do*not*. Just because a battery "fits" (physically) the device, does not mean that it is advisable, or even sensible, to do use it in that device. Comment: If you get a new battery charger, as well as the batteries, and the batteries have to be removed from the phone to be charged, then the issue above is moot. If the batteries are automatically recharged when the phone is in the base station (typical), the above *does* apply. Note: "memory effect" in NiCD batteries is mostly a thing of the past; newer designs have all but eliminated the issue. ------------------------------ From: Michael D.

The NiMH battery will power the phone just fine, once it's charged. But you need to have a charger designed for NiMH batteries. Some Ni-Cad chargers also are designed to charge NiMH batteries, but some are not. (I assume there is a difference in charging current or something.) Don't use NiMH batteries in a charger designed only for Ni-Cads. Since you will undoubtedly be charging the batteries in the phone, not swapping them out into a charger, you shouldn't use NiMH batteries in a phone that says to only use Ni-Cads. The only exception I would make to this is if the phone vendor sells a NiMH replacement battery specifically intended to be used in the phone in question. And I would go with the vendor's battery, in that case. Michael D. Sullivan Bethesda, MD (USA) (Replace "example.invalid" with "com" in my address.) ------------------------------ From: Gene S.

PAT] There has been a rash of "exploding" cell phone batteries, primarily caused by bootleg Asian import batteries that lack thermal protection devices. Also, the charging characteristics for NiCd are different than NiMH. The charger could cause a NiMH battery to overheat, or at least reduce its useful life. --Gene ------------------------------ From: firstname.lastname@example.org (Scott Dorsey) Subject: Re: Can I Substitute a NiMH Battery for NiCd in a Cordless Phone?

Memory effect basically has not existed for many years now. It used to be a serious problem, but today most NiCd failures are caused by people reverse-charging cells as they overdischarge packs in an an attempt to avoid nonexistent memory problems. If you put a NiMH pack into the thing, you will get more capacity at first because the energy density of the pack is higher. But because the charger is not designed for NiMH cells, you will find that the battery pack doesn't last very long before it fails. If the phone works, why screw with it? --scott "C'est un Nagra.

NiCd and NiMH use very different chargers. You can not successfully charge an NiMH battery in a phone designed only for NiCd. It's quite possible that the new battery will vent itself if you install it. Not exactly a fire or explosion (both of which are pretty unlikely), but your phone will probably be wrecked by it nonetheless. * * PV something like badgers--something like lizards--and something like corkscrews. ------------------------------ From: FrazNor@gmail.com Subject: Re: Surveillance Cameras More Common Everyday Date: 18 Apr 2005 07:45:27 -0700 Organization: http://groups.google.com Here is one on Times Square: http://images.earthcam.com/ec_metros/ourcams/fridays.jpg Refresh as needed. [TELECOM Digest Editor's Note: The one you mention, and three or four other cameras are used at Times Square (34th and Broadway if my memory is correct) in the program Webcam Watcher, an interesting piece of software for Windows. Independent people, with web cams at fixed locations, donate the output from the cameras for use by voyeurs on the net who like looking at things. The writer of the Webcam Watcher program has a directory of about _three thousand_ such locations all around the world. He gives you thumbnail images of all of them on your screen; allows you to manually choose any of them, or have the program function like a 'scanner' (doing a big image) of one after the next, just like a radio scanner operates, working its way to the end of the line and starting over again. If a repretoire of three thousand images seems a bit much to deal with, you can also select a smaller number from the indexes of same, or the thumbnails and concentrate on just those; for instance, those cams active in the past minute, the past five minutes, etc. Some are in constant operation; others only snap a picture of their surroundings every hour, etc. You select the desired cams from the indexes of same, and make up your own list of what to scan whenever one or more of them takes a new picture. If your 'active scan directory' is too large, the big pictures on your screen change every second or two. If it is too small, then you can actually look at and study a picture for a few minutes before the next image (from some other location) comes through, like a radio scanner. Webcam Watcher is _not_ intended as a sex thing at all. He has that type of cam (adult) in the master index, but they are all isolated so you can choose that kind of thing "if you like to watch" but the majority of the cams are just 'regular' scenes, such as expressway cams in Japan (some also from Georgia highways), parks and gardens; a few cams are scenes of the border crossings in Texas, Arizona and California and Detroit, MI; I have one of my weather station cam in his directory, etc. There is one of the ships going through the Panama Canal, some absolutely stunning cam images of mountain tops in Alaska and Wyoming, etc, people's homes, school classrooms, about a dozen cams in New York City (including the several in Times Square), Chicago, San Francisco, etc. I get sort of depressed using the program, since there are so many absolutely delicious views of absolutely wonderful cities and sites I would dearly love to be young enough -- and well enough -- to to visit and see in person, but I know I will never get to see in person, a beach in Australia, or a coffee house in Indonsia for example. If you have a cam with a public display you welcome people viewing, _and you have the WebCam Watcher program_ consider adding the locations of these files to the directory he updates from time to time. Just Google for 'Webcam Watcher'. He has both free and paid copies of the software.

Those little devices that do phone patches for amateur radio operators connect to telephones that are part of the public switched network. As such, the group operating the patch equipment pays the local exchange company for the monthly charges on the line. As the telephone lines are obtained from the local exchange company, or a competitor they are subject to all the rules and do provide ANI/ALI information to the PSAP. The other point to remember is that phone patch equipment is normally operated (triggered) by a licensed radio operator who presumably would know the limitations of the connection.

Perhaps there is something I have overlooked in my > assessment of the risks vs. rewards of PPC advertising. Yup. There is. Q. "What is an ad worth?" A. "Depends on how many people see it." This is why a 30-second spot during the SuperBowl costs more one on that same network at 3:00AM on a Tuesday. Advertisers by space based on "cost per M" -- i.e. how many dollars does it cost to geth their ad in front of a thousand potential 'customers'. What they will pay "per thousand impressions" depends on how likely somebody is to _buy_, after having encountered the ad. Things/places with higher rates of sales "conversions" are worth more 'per thousand' than those with lower conversion ratios. Given similar conversion ratios, the place delivering the larger number of impressions is worth more than the site with the smaller number of impressions. Before an advertising buyer enters into _any_ contract for ad placement one of their first questions is guaranteed to be "how many people will see this ad?" It doesn't matter _how_ the space is priced -- flat rate or $/M -- they want to know how many people it will reach. Note: along this line, TV/radio ad contracts (especially for "new" programming) usually specify a minimum vievership level -- if the subsequent ratings show that that level wasn't reached, the stations/networks are committed to run 'extra' ads to ensure the required number of 'impressions'. There are parallels in print advertising -- particularly when a new publication is starting up. With web-pages, there is *no*way* to estimate how many people see any particular ad. *OTHER* than to count how many times it was displayed. And that is not a "reliable, accurate" number, by any means. What it is, however, is the "best available" data for estimating. "Smart" web-advertising buyers, have been, for _years_, specifying that they will pay only for "unique" clicks -- only one hit from a given IP address within a specified time-frame (minimum hours, sometimes days). > It seems that PPC advertising is going to be a fixture in web > advertising.

It's _always_ a "guessing game". You *cannot* know whether a given click -- or pattern of clicks, even -- is legitimate or fraudulent. The ROM in computers does *not* stand for "<R>ead <O>perator's <M>ind" which is the necessary pre-requisite for making a 100% accurate determination. > I'd also like to know if there are any technical groups that are > studying the issue and proposing solutions.

(This is especially the > case for the largest search engines.) Consider a "fleet" of 500,000 "zombie" PCs, scattered across three continents. Each machine, _once_a_day_, at a random time, connects to a given web-page, without anybody in front of the machine. Now, just _what_ are you going to detect? Consider an ISP who gives all it's customers RFC-1918 addresses, and does NAT/PAT to a relative handful of 'public' IP addresses. And something shows up on slashdot (or similar) that gets "everybody" on that network going to look at the particular page (and ads). Suddenly you see a sh*tload of queries coming from the _same_ IP addresses -- including multiple simultaneous connects from a single address, just with different source ports. How do you differentiate _that_ from a single box with a click-bot running? How do you differentiate _that_ from a single box with a click-bot *behind* the NAT/PAT device? An IP address is part of a DHCP pool. You get a number of clicks from that address at widely separated times. Is that all one user, or is each from a different user, who just happened to get that address fort their dial-up session? How do you *know* whether that address is a DHCP pool address or not? ------------------------------ From: Yammie <firstname.lastname@example.org> Subject: Clarisys VOIP USB Phone Date: 18 Apr 2005 09:58:18 -0700 Organization: http://groups.google.com Barely used E-bay Item # 5768559922 ------------------------------ TELECOM Digest is an electronic journal devoted mostly but not exclusively to telecommunications topics.
