• As SMDR software is put into use users often discover that a lot of calls are quickly recorded by the software. A simple SMDR call accounting software solution records each call in a database (as it should) without any thought to how the calls will be used.
• Station Message Detail Recording (SMDR) captures detailed information about incoming and outgoing voice and data calls. The information is sent to an output device such as a printer or an optional call accounting or analysis system. SMDR records are gathered sequentially and sent to the RS-232 SMDR jack on the processor module of the control unit.
• We are not looking to replace the Call accounting software as the same program tracks their copies,postage,calls and matereal on a per client basis. They just don't have an SMDR IP collector module with their software. All we have to do is provide a ASCII file every night so they can import the SMDR from.

Regardless of their size, most telephone systems output CallDetail Records (CDR). Generally, these are created at the end of acall. But on some phone systems, the data is available during thecall. This data is output from the phone system by a serial linkknown as the Station Message Detail Recording port (SMDR).

For Telecom Providers Only: Enghouse call accounting software helps businesses manage, transition and optimize their communications systems through detailed monitoring and reporting of system and trunk usage, cost analysis and other business KPIs.

Some of the details included in call records are: Time, Date,Call Duration, Number dialed, Caller ID information, Extension,Line/trunk location, Cost, Call completion status.

What really happened to Amelia Earhart?

Amelia Earhart, the first woman to pilot a non-stop flight across the Atlantic Ocean, disappeared on July 2, 1937, during her attempt to fly around the globe. She was legally declared dead on Jan. 5, 1939, but nobody knows precisely what happened to her. In the years since her disappearance, researchers have posited a number of theories, some of which are more credible than others. Let’s look at a few possible explanations: 1. She ran…

What are some interesting facts about left-handed people?

Here are a few of the most interesting facts about lefties (and by the way, this answer was written by a lefty): Four of the last six U.S. presidents were lefties. Ronald Reagan, George H.W. Bush, Bill Clinton, and Barack Obama were left-handed. George W. Bush and Donald Trump are righties. Overall, eight of the 45 American presidents have been lefties (the others are James Garfield, Herbert Hoover, Harry Truman, and Gerald Ford). Lefties make…

What is true, half true, or a complete fabrication we tell students about the first Thanksgiving?

We all know by now—or at least we should—that what our history textbooks told us in school is not exactly the gospel truth. Time and centuries’ worth of oral and written tradition tend to distort and reshape the facts to the sensibilities of modern audiences, so one person’s intrepid discoverer of the Americas becomes another person’s

What are the best books from your childhood that every kid should read?

You might say the books you read when you were a child are some of your fondest memories growing up. You may even go on to say these tales you enjoyed with loved ones or by yourself contributed to the person you became as an adult. It’s a solid truth that reading to children and spending time with them creates a bond that can last for a lifetime. When you’re ready to begin your literary…

How do we get our dog to stop passing gas?

Dog farts are no joke. Canine flatulence can clear out a room and ruin a sweet, cuddly moment in an instant. Your pet might not seem to be bothered by their gas, but if you're reading this, you probably are. And there's a good reason to take doggie gas seriously: Along with other symptoms that we'll get into in a little bit, excessive gas could indicate gastrointestinal issues or a food allergy, according to PetMD…

Who wrote the Statue of Liberty poem?

Emma Lazarus wrote the sonnet “The New Colossus” on Nov. 2, 1883 as part of a fundraising effort for the construction of the Statue of Liberty’s pedestal. Lazarus was born on July 22, 1849, into a wealthy Sephardic Jewish family (Sephardic Jews descend from people who were expelled from Spain during the Inquisition in the 15th century). While her Jewish heritage played a minor role in her early work, it eventually became a major part…

What are some things about Americans that make non-Americans cringe?

Tourists adventuring in America are losing their appetites over conversations about tipping. After all, what's the fun of facing off against an absurdly-sized triple cheeseburger that could feed a family of four if you're focused on remembering the guidelines of gratuity. Oh wait; that's right, there are no guidelines! Instead, there are only arguments about percentages for tourists to contemplate as they chew and that's enough to put a bad taste in their mouths that…

Where does the saying 'bite the bullet' come from?

The exact origins of the phrase are difficult to pin down, but it’s generally attributed to the practice of biting on a bullet during warfare to deal with pain or discomfort. According to one theory, soldiers would bite bullets during field amputations during the Civil War. Patients would either die or “bite the bullet' and undergo a horrific operation. The lead balls, while not exactly nutritious, would absorb the bite without damaging their teeth. While…

What is the best way to fold a fitted sheet?

There’s really only one way to fold a fitted sheet without succumbing to the frustration that usually accompanies the task. The elastic bands do present an issue, see, and most of us end up shoving unfolded linens into our closets. That wastes space, and it’s completely unnecessary—folding a fitted sheet is fairly simple, once you’ve mastered the technique. Here’s the best method: Start by holding the sheet lengthwise by the top two corners (the short…

Where does 'bury the hatchet' come from?

It comes from a tradition followed by some Native American tribes. At the end of a war, the tribes' chiefs would literally bury a hatchet as a symbolic gesture of their new peace. Not all tribes followed this tradition. However, it likely predated the European settlement of the Americas, and it was seen as a solemn and important ceremony. One 1664 account describes the Iriquois proposing peace as “proclaim[ing] that they wish to unite all…

Where does the phrase 'run the gamut' come from?

It’s based on a musical notation system used in the Middle Ages. First, let’s look at Merriam-Webster’s definition of the phrase: “To encompass an entire range of something. Ex: Her emotions ran the gamut from joy to despair.” To put that another way, “run the gamut' means to go from the start of something to the ending, and this meaning has an origin in medieval music theory. The monk Guido of Arezzo developed a system…

What do roly polies taste like?

If prepared well, they taste similar to shrimp. And yes, they’re edible. Contrary to popular belief, roly polies (also known as pill bugs, doodle bugs, potato bugs, and by their scientific order name, Armadillidiidae) aren’t insects or arachnids. They’re land crustaceans, and as such, they’re more closely related to lobsters, crayfish, and shrimp. As a general disclaimer, you shouldn’t eat random crustaceans you find walking across your basement, but if you decide to eat roly…

How do you flip a coin?

Norstar Smdr Software

Here’s the basic process. After you’ve got this down, we’ll look at a few ways to influence the outcome of the coin flip. Step One - Make your hand into a fist, wedging your thumb against your index finger or in the crease between your index finger and middle finger. Point the thumb side up. Step Two - Place the coin on top of your fist on the space between your thumb and index finger…

Is the person who types up movie credits in the movie's credits?

Sometimes, but not typically. The film’s producer makes that decision. Many film productions outsource it to a motion graphics company like Scarlet Letters, which claims to be the number one company in the world specializing in end titles. The company might receive a credit for that work, but the specific person who types the names into the end credits won’t usually receive their own individual credit. That’s because they’re not doing a ton of work—the…

How many shuffles does it take to randomize a deck of cards?

The answer depends on the type of shuffle you use. With a bit of math, we can determine that a brand-new deck will be effectively randomized after seven traditional (or “riffle') shuffles. First, a quick definition of a riffle shuffle: Divide the deck into two roughly equal halves, then use your thumbs to pull up (or down) on the ends of each stack. Allow the halves to fall so that the cards alternate. If you’re…

Why did Apple remove the headphone jack?

Apple’s position is that the headphone jack is an old technology, and that its removal allows the company to produce better phones with more features. Specifically, the removal of the headphone jack allows Apple engineers to do more with the iPhone’s architecture. “It was holding us back from a number of things we wanted to put into the iPhone,” Apple executive Dan Riccio told BuzzFeed News. “It was fighting for space with camera technologies and…

What are some crazy ways to tie a necktie?

We’re not here to talk about your Windsors, Half-Windsors, Prince Alberts, or Kelvins. No, we’re here to show off some of the craziest necktie fastenings out there so you can really step up your tie game. Check out this diverse collection of unconventional knots. Eldredge Knot. This unorthodox and ostentatious knot involving 15 separate steps is named after its creator, Jeffrey Eldredge, who invented this complex procedure in 2007. Unlike the majority of necktie knots…

How long can I eat food after its expiration date?

You can eat most foods after their expiration date, but dozens of factors can affect food spoilage. Contrary to popular belief, the Food and Drug Administration (FDA) doesn’t require manufacturers to list an “expiration,” “use by,” or “sell by' date, with one notable exception that we’ll cover in a moment. Some states require the labels on some foods, but for the most part, manufacturers apply them at their own discretion. Manufacturers want consumers to have…

What is cloud seeding?

Imagine a world where drought-ridden areas can get the rain they need, on demand. A place where airports can eliminate dangerous fog that could potentially lock thousands of passengers on land and compromise the safety of those in the air. Think about having the ability to reduce the size of hail during thunderstorms, especially in areas that see frozen pellets the size of softballs wreak havoc on homes and property. Although these scenarios sound like…

How come lemonade mixes use artificial lemons, but furniture polish uses the real thing?

To put it simply, you want lemonade mixes to taste good, and you want furniture polish to actually clean your stuff. First, one issue with the question: Some furniture polishes don’t use lemon, even if they’re advertised as “lemon scented.” Likewise, some lemonade mixes use real lemon flavoring, but many use natural flavors like citric acid to provide the tart flavor that consumers expect. That citric acid can come from citrus fruits, although it can…

Can you ever really be friends with an ex?

Yes, you can be friends with an ex. Whether or not that's a good idea depends on your personality, your ex's personality, the nature of your relationship, and a host of other factors. For many people, the idea of staying friends is untenable. After all, that's why breaking up is called 'ending a relationship.' In most cases, the relationship...ends. Scientists have looked into post-breakup friendships, and some of the research has interesting implications for these…

Will Equifax really pay $125 to every American affected by its data security breach?

No. Equifax will issue payouts to those affected by the company’s 2017 data breach who file a claim, but the amount of those payouts will be much, much less than $125. Here’s the deal: In July 2019, Equifax reached a $700 million settlement with the Federal Trade Commission (FTC) and other government entities. As part of that settlement, the company agreed to pay up to $125 to each American affected by the breach. The FTC…

What are some facts you were taught in school that are no longer true?

If you hold your face like that, it’ll get stuck that way. At least, that’s what your elementary school teacher probably told you. (Also, why were you pulling so many goofy faces when you were supposed to be focusing on the math lesson?) As an adult, of course, you see how ridiculous that claim turned out to be—unless you’re one of the few people whose faces did stay that way, in which case we are…

Do you call little donut balls 'munchkins,' 'timbits,' or 'donut holes'?

You can call them whatever you’d like, as all three names are acceptable. However, if you’re trying to order them from a bakery, you might have better luck with one of these names, depending on where you’re at. First, a brief description of the treat so that we all know what we’re talking about: They’re small, fried balls of dough, identical in taste to a donut. They might be sprinkled with sugar, cinnamon, sprinkles, or…

Does any country own the moon?

Not officially. While the United States planted a flag on the moon, the astronauts' intention wasn’t to claim ownership, and there’s actually an international treaty that forbids any country from claiming the moon (or other celestial bodies) as its own. Back in the late 1950s, there was significant global concern that a country would eventually try to weaponize outer space. After the Soviet Union successfully launched Sputnik in 1957, the United Nations General Assembly formed…

Does everyone see colors the same way?

The short answer: Probably not, but most people still get the same emotional experience from looking at the same colors. To really address this question in detail, however, we need to consider two factors that affect how we see color. The first factor is the rods and cones in the retina of our eyes—the “hardware” that detects light. Rods detect light and dark, and cones detect color. There are three types of cones, which individually…

Is cereal a soup?

Much like the question of whether or not a hot dog is a sandwich (it isn’t, really), the answer here depends on how you define the terms. Here’s the Merriam-Webster definition of soup: “A liquid food especially with a meat, fish, or vegetable stock as a base and often containing pieces of solid food.” While you could make the case that a cereal qualifies as a “liquid food,” it’s not made with any sort of…

What Were The 5 Biggest Archaeological Discoveries Of The Last Decade?

Can you believe it’s been nine years since the last Indiana Jones film came out? As much as we might wish to forget Shia LaBeouf swinging from vines amidst a family of monkeys, the reality is that Harrison Ford’s scruffy-faced adventurer made archaeology cool for generations of young boys and girls. Now, a similarly exciting first look at the rebooted Tomb Raider franchise proves Alicia Vikander’s Lara Croft is set to become Jones’ worthy successor…

Brain Freeze, Goose Bumps, And Other Weird Stuff Your Body Does Without Asking. What are they?

Ever wonder where “brain freeze” comes from? What about the hiccups? How about goose bumps? While you might not spend much time thinking about these strange body phenomena, they’re fairly complex neurological events. In some cases, they serve important biological functions (or they did at one time). James Giordano, PhD, is a professor in neurology and biochemistry at Georgetown University Medical Center. We spoke with him to discuss some of these strange neurological phenomenon—and to…

What's the best way to survive a shark attack?

First of all, understand that your risk of a shark attack is incredibly small unless you purposely swim around sharks. Beaches can be dangerous places, but sharks aren’t a serious risk at most of them; according to the International Shark Attack File (ISAF), your chances of drowning are 1 in 2 million, while your chances of a shark attack are 1 in 11.5 million. Shark attack fatalities are even more rare. In 2018, four people…

What happens in a Formula One pit stop?

As of 2019, an F1 pit stop typically involves a tire change and a front wing adjustment. Up to 20 team members perform a perfectly choreographed set of actions to get the car back onto the track as quickly as possible, often completing their work in two seconds or less. Currently, Red Bull Racing holds the record for the fastest pit stop at 1.88 seconds. For pit crews, consistency is more important than breaking records—but…

What were tv moments that were almost fatal?

The Brady Bunch In the episode 'The Cincinnati Kids,' the script called for the cast to be filmed riding a rollercoaster. However, the camera that was mounted at the front of the coaster looked loose to Robert Reed (aka Mike Brady), and he ordered a test run of the coaster to ensure safety. Reed's gut proved to be right as the camera flew off its mount, and it would have potentially killed the cast had…

What is the difference between a copyright and trademark?

Both copyrights and trademarks protect intellectual property, but they differ in several significant ways: Usage - Per the United States Patent and Trademark Office, a copyright protects any original work “fixed in any tangible medium of expression.” That could include books, poems, business reports, and any other intellectual work. The copyright holder also holds exclusive right to produce derivative works—if a new songwriter wants to sample an original composition, they’ll have to get permission from…

What are the most haunted places in the world?

Čachtice Castle, Slovakia.In the early part of the 17th century, a Hungarian countess named Elizabeth Bathory was accused of murdering some 650 women across what is today known as Slovakia. Legend has it that Bathory's servants lured young women to Čachtice Castle with the promise of work and education, only to help butcher them. Although she was never officially punished for her crimes, the infamous murders said to take place at the castle have led…

Do the Russians have all my photos and data now that I've downloaded FaceApp?

The FaceApp mobile application does present some serious privacy concerns, based on a reading of its terms and conditions. However, it would be inaccurate to say that the app steals “all of your data,” or that it gives its developer permanent access to all of your photos. It’s also inaccurate to say that the app gives user data to “the Russians,” but we’ll take a closer look at that question in a second—in short, the…

What were Rutger Hauer's most memorable movie roles?

What are the largest earthquakes to ever hit the United States?

In terms of magnitude, the largest earthquake ever measured in the United States occurred on March 27, 1964, in Alaska, registering a whopping 9.2 on the Richter scale. If you’re looking for more information, here’s a breakdown of the largest U.S. earthquakes by magnitude. Note that when discussing the biggest earthquakes in history, there’s a minor issue: Charles Richter invented his magnitude scale in 1935, and earthquakes prior to that are assigned magnitudes based on…

How is the Nintendo Switch Lite different from the original Switch?

The primary difference between the Nintendo Switch Lite and the original Switch is that the Switch Lite is designed strictly for portable play. It cannot be docked or hooked up to an external screen, and its controls are a permanent part of the device (as opposed to the original Switch’s detachable Joy-Con controls). The new console also has a direction pad (or D-pad) incorporated into the left side of its face. As such, it’s more…

What were some of the best gadgets from the James Bond movie franchise?

Ranging from iconic to absurd, here’s some of the more memorable pieces of technology that 007 came in contact with. Walther PPK (Dr. No).It’d be difficult to talk about gadgets in the James Bond movies without mentioning his iconic firearm. Introduced by his superiors, the Walther PPK became Bond’s weapon of choice for…

When people say 'blown to smithereens,' what are the smithereens?

The “smithereens' in question are small pieces of something. The word entered the English language in the late 1700s, per Merriam-Webster. It probably comes from the Irish Gaelic smidiríní, which roughly translates to “little bits.” Usually, “smithereens' refers to the small bits created by an explosion or a sudden impact. So, why do people use the phrase “blown to smithereens,” and why don’t we ever refer to “smithereens' on their own? You’ll never hear someone…

What was the Billboard controversy with 'Old Town Road'?

Lil Nas X’s “Old Town Road' debuted on Billboard’s Hot 100, Hot Country, and Hot R&B/Hip-Hop Songs charts, thanks in part to the rapper’s tireless self-promotion efforts. The song spread virally, but as it climbed the rankings, Billboard quietly removed it from its country charts. That decision sparked controversy, along with conversations about what “country music' really means in 2019. In a statement to Rolling Stone, Billboard explained that “upon further review, it was determined…

Ferrari 308 GT4…

Why don't cooking sprays have any calories?

They actually do have calories—for the most part, they’re the same oils you’d find in bottles on store shelves, along with propellants and a few other ingredients (which we’ll discuss in a moment). However, if you check the nutrition facts on a bottle of cooking spray, you’ll often see “Calories: 0.” You might also see them marketed as “fat free.” What gives? Look closer on that bottle, and you’ll see a serving size of “one-third…

Why don't American stores just add taxes to the price tags?

For starters, sales taxes are handled at the state and local levels. Five states don’t have sales taxes: Alaska, Delaware, Montana, Oregon, and New Hampshire. Some states have a high sales tax—currently, Tennessee leads the pack with a hefty 9.47 percent rate. In California, many cities have their own sales taxes, which can push the total rate to over 10 percent. If a company operates on a large scale, they’d have to price every product…

Why do mosquitoes prefer some people over others?

What is ASMR?

ASMR stands for autonomous sensory meridian response, and it’s a phenomenon some people experience when exposed to certain auditory/visual stimuli. To put that in plain English, it’s a relaxing, tingling feeling that occurs when you watch certain videos or listen to certain sounds. In the YouTube era, ASMR has exploded in popularity. Creators make videos designed with various “triggers' intended to give people the sensation—and some of those videos have tens of millions of views…

What's in Area 51?

The quick answer: Nobody really knows for sure...however, there probably aren’t any aliens there. Nonetheless, we’ve got some information on the legendary site’s secrets. First, a quick primer: Area 51 is about 150 miles from Las Vegas, Nevada, and it’s a military testing facility shrouded in secrecy. You won't hear the government call it Area 51—publicly, they use names like Groom Lake, Homey Airport, or the Nevada Test and Training Range. The United States government…

A call detail record (CDR) is a data record produced by a telephone exchange or other telecommunications equipment that documents the details of a telephone call or other telecommunications transaction (e.g., text message) that passes through that facility or device. The record contains various attributes of the call, such as time, duration, completion status, source number, and destination number.^[1][2][3] It is the automated equivalent of the paper toll tickets that were written and timed by operators for long-distance calls in a manual telephone exchange.

CDR contents[edit]

A call detail record contains data fields that describe a specific instance of a telecommunication transaction, but does not include the content of that transaction. By way of simplistic example, a call detail record describing a particular phone call might include the phone numbers of both the calling and receiving parties, the start time, and duration of that call. In actual modern practice, call detail records are much more detailed, and contain attributes such as:^[2][3]

• the phone number of the subscriber originating the call (calling party, A-party)
• the phone number receiving the call (called party, B-party)
• the starting time of the call (date and time)
• the call duration
• the billing phone number that is charged for the call
• the identification of the telephone exchange or equipment writing the record
• a unique sequence number identifying the record
• additional digits on the called number used to route or charge the call
• the disposition or the results of the call, indicating, for example, whether or not the call was connected
• the route by which the call entered the exchange
• the route by which the call left the exchange
• call type (voice, SMS, etc.)
• any fault condition encountered

Each exchange manufacturer decides which information is emitted on the tickets and how it is formatted. Examples:

• Send the timestamp of the end of call instead of duration
• Voice-only machines may not send call type
• Some small PBX does not send the calling party

In some corporate Private branch exchange (PBX) systems, a call detail record is termed a station messaging detail record (SMDR).^[4]

Uses[edit]

Call Accounting Software

Call detail records serve a variety of functions. For telephone service providers, they are critical to the production of revenue, in that they provide the basis for the generation of telephone bills. For law enforcement, call detail records provide a wealth of information that can help to identify suspects, in that they can reveal details as to an individual's relationships with associates, communication and behavior patterns, and even location data that can establish the whereabouts of an individual during the entirety of the call. For companies with PBX telephone systems, call detail records provide a means of tracking long-distance access, can monitor telephone usage by department or office, and can create listing of incoming and outgoing calls.

Privacy[edit]

The U.S. Supreme Court has held the records of numbers called are not protected by the Fourth Amendment to the Constitution of the United States because the caller 'voluntarily conveyed numerical information to the telephone company.'^[5] But there is limited protection under the Electronic Communications Privacy Act. The revelation that call metadata records are being universally collected and stored in the U.S. and elsewhere has generated considerable controversy.

In June 2013, a top secret order of the United States Foreign Intelligence Surveillance Court was leaked to the public. That order referenced and defined call detail records as follows:

'IT IS HEREBY ORDERED that, the Custodian of Records shall produce to the National Security Agency (NSA) upon service of this Order, and continue production on an ongoing daily basis thereafter for the duration of this Order, unless ordered by the Court, an electronic copy of the following tangible things: all call detail records or 'telephony metadata' created by Verizon for communications (i) between the United States and abroad; or (ii) wholly within the United States, including local telephone calls....

'Telephony metadata includes comprehensive communications routing information, including but not limited to session identifying information (e.g., originating and terminating telephone number, International Mobile Subscriber Identity (IMSI) number, International Mobile station Equipment Identity (IMEI) number, etc.), trunk identifier, telephone calling card numbers, and time and duration of call. Telephony metadata does not include the substantive content of any communication, as defined by 18 U.S.C.§ 2510(8), or the name, address, or financial information of a subscriber or customer.'^[6]
