How to Evaluate Voice Quality in VOIP Network

VoIP or Voice over Internet Protocol is one of the most popular and effective communication services. VoIP transform voice signals into data packets and transmit them over the internet from one point to another. The use of IP phone has gained immense popularity among small, medium and large businesses. This is largely because it reduces the expense of call transmission.

VOIP-Network

Quality of calls in VoIP has always been a contentious issue. New VoIP or IP phone users are often doubt the quality of calls. Usually people fail to realize that faulty network and low bandwidth results in call quality issues. VoIP implementation has some basic prerequisites. Users will be able to get rid of quality issues forever once these perquisites are fulfilled.

Quality evaluation is needed to grade the call quality of IP phone calls. It helps in evaluating the technical and commercial viability of a communication technology. Similar techniques are used for both improving quality of VoIP call and quality evaluation. This generally involves subjective as well objective voice quality measurement.

Internet-Based MOS Test

MOS test methodology is an extremely popular test to assess the quality of the VoIP network. The test involves quality assessment of the codecs and it can be difficult due to subtle differences in the codecs. Besides this packet loss instances and various limitations of IP phone VoIP applications also need to be taken into account. It has been proven that packet loss is far more fatal than the faulty codecs.

Evaluation of the Voice Quality

This evaluation method uses a PC-based software system. The software simulates key processes of the VoIP technology used by an IP phone. At the same time quality of the speech is also evaluated. It measures the objective voice quality by using ITU PESQ and E-Model evaluation. Comparison between internet-based MOS assessments and more conventional MOS evaluation can also be drawn.

Measurement of Intrusive Conversational Speech Quality

Intrusive Conversational Speech Quality is a great method of predicting one-way speech quality. However, it does not take into account the impact of the end-to-end delay; a vital component of interactivity in communication. This particular test is a conversational method of quality measurement. It truly and properly exploits the accuracy of the Perceptual Evaluation of Speech Quality (PESQ) algorithm.

Non-Intrusive Objective Measurement

There has been an extension of the elementary E-model in multiple directions. This has been coupled with the non-intrusive monitoring of quality for VoIP applications. However, the equation of equipment impairment in case of this assessment is based on the subjective tests. These are conducted to obtain the model parameters for each codec, application as well as the condition prevailing within the network. Naturally, this is pretty time consuming as well as impractical method. It may even prevent the development of a cognitive E-model for designing the future IP phone applications.

Time to turn the attention on structured cabling


A structured cabling system can be defined as a comprehensive system or network of cables and associated hardware devices that collectively offer a holistic telecommunication infrastructure and a platform on which an overall hierarchy or system of information is established.
Structured cabling is the foundation of today’s business houses, government organization, and so on. It is also the base of today’s IT network including data voice, alarms or videos. It also defines the transmission patter of the signals through the communication network.

Structured-Cabling

Structured cables are set up and maintained by the contractors who are specialized in this area networking technology. Now, this ensures that the structured cabling system that they set up is absolutely seamless and is best fitted to meet the needs of the businesses. However, the methodology of setting up a structured cabling system is a generic one and is standardized. The standardization the procedure is imperative as it is imperative for the businesses to ensure a universally accepted system performance rather than a complex arrangement, which might put the companies in tight fix.

Even though the methodology of setting up structured cabling system is a generic and standardized one, each and every system develops s a unique identity after it is set up. This ensures that it is absolutely safe and there is no chance of any data pilferage, which is the last thing that a business organization would want to happen. Here are the factors that make each and every structured cabling system is unique.

  • The cables and the connection products used

  • The structure of the architecture of the business premises or the building, where the system is being set up

  • The functionalities of the cabling installation

  • The types of the apparatus and the equipment that the cabling system is expected or intended to support – at present and in the short as well as long term future

  • The configuration of the system that is already installed (if any)

  • Requirements of the customers and the warranties of the manufacturers

Here are the benefits of having a structured cabling system:

  • The communication becomes fast, cost effective as well as reliable. Most importantly, the cabling system is suitable and effective for any type of infrastructure

  • In case the business wants to relocate, the system is flexible enough to be taken down and refitted at the new location with hardly any hassle

  • The system is adaptable o future improvements as well as additions

  • This type of system ensure better and more authentic data encryption, and offers more safety and better and safer storage facilities

Data as well as voice management

Structured cabling helps in simultaneous data as well as voice management and this helps the business to put in the two aspects of communication under one umbrella, thereby reducing the cost and the botheration by a significant aspect.

Talking about them separately, data cabling can defined as setting up of a network of cables that relay or transmit data from one point or place to another. Data cabling helps to set up communication between an effective communication between multiple users and helps analyze the exchanged data at a centralized point.

Voice cabling, on the other hand is the network of cables that helps in setting up of the basic communication, which also includes the land based telephone system, modems and the analog lines.

Structured cables put these separate genres of functionalities within one bracket, thereby setting up a unique data transfer system that indulges in data as well as voice management simultaneously and that too in a seamless and effective way.

This unique feature of this system compels the companies to more and more shift towards structured cabling.

Self-Medication and Mental Illness: Know the Signs

Mental illness is notorious for causing sufferers to self-medicate. Most often, self-medication is very harmful, sometimes resulting in overdose or other physical consequences. Here are a few common forms of self-medication and how to recognize them as substance abuse.

Excessive Alcohol Consumption

Addiction

Alcohol is one of the most common ways that people self-medicate in order to cope with various mental illnesses, from  bipolar disorder to depression, schizophrenia, and more. It is, for the most part, socially acceptable to drink regularly and is very easy to acquire. Alcohol quiets the mind, forcing it to slow down and relax. For many mental illness sufferers, this is all they want to experience, even if it is only for a few hours.

Some signs of alcohol abuse might be shirking responsibilities at home or work in favor of drinking, drinking as a response to stress, or frequently drinking with a seeming inability to go without alcohol. A person who is abusing alcohol may also attempt to hide their drinking while a self-medicating person may also combine alcohol with medications despite dangerous results.

Tobacco Use

Tobacco is known for soothing nerves, limiting anxiety, and reducing stress, which is why many people in high-stress jobs can be seen smoking on their breaks. As a form of self-medication, tobacco can ease anxiety and panic on top of potentially treating some symptoms of  schizophrenia. A surprising number of people with schizophrenia become hooked on tobacco with studies showing that smoking can genuinely reducing symptoms such as sensory and cognitive deficits.

Signs of  tobacco abuse include withdrawal, planning days around smoke breaks, irritability without a certain amount of nicotine, and continued smoking despite any emerging health concerns.

Marijuana Consumption

Marijuana is likely the least detrimental form of self-medication. Though smoking marijuana has been shown to have some negative side effects, including short-term memory loss, marijuana is the lesser of many evils when compared to most other addictive substances. Marijuana permits the person to relax and can combat the effects of anxiety and depression. However, a dependence on any substance is never beneficial.

Signs of marijuana abuse can include withdrawal, problems sleeping without using the substance, a distinct smell, and regular use.

Prescription Medication Abuse

Prescription medication addiction often occurs accidentally. Since these treatments are prescribed by doctors, patients may fail to realize the dangers of overdosing. Overuse of these medications may be an attempt to treat worsening symptoms or to simply up the dosage if the prescribed dosage is not helping enough.

It is fairly easy to recognize prescription drug misuse. The prescribed dosage will be available on the container. If the person is exceeding the dose having not consulted their doctor, they may be at risk of addiction. They may also experience severe withdrawal without the substance or may notice that their usual dosage has become ineffective.

Intentional abuse can be harder to spot as the user will be concealing their actions. A sudden change in moods, behaviors, or temperament is often cause for concern if you are aware that the person is taking prescription medications.

Self-medication is all too common in a society where mental illness is rampant and medical care is difficult to obtain. Some people are able to cope with mental illness simply by cultivating positive coping strategies such as exercise, meditation, and a healthy diet. For others, medication is necessary. It is always best to consult a doctor for approved treatments and to seek help from a counselor for non-medical recommendations.

Is VOIP Technology Going Social?

No one can deny the impact of social media on the global population and the way it has affected business across the world. Facebook, Twitter, LinkedIn and many other social media platforms are continually using new ideas to connect individuals. How can VoIP or Voice over IP be left behind? VoIP too has been affected by the social media revolution and its integration is becoming more and more obvious.

Is VOIP Technology Going Social?

Innovations in social media with VoIP being the focal point

Almost all the popular social media platforms were initiated in the form of desktop websites. However, with mobile devices gaining prominence, the social media platform too evolved. Though initially these sites were not meant to be mobile but they changed for the better. Nowadays, the social media innovations are built around VoIP and all innovations keep VoIP as the focal point.

If we take a closer look at mobile apps like WhatsApp, and Viber, we can see that here the users are able to share text, images and video with one another. Though these sites are not as big as Facebook but their very existence is based on VoIP. Making calls and messages are sent over the internet. Well, the days of social media built around the VoIP has already started and things are getting better and better with every passing day.

Facebook Too Is Making Its Move

Zuckerberg has created the best ever social media platform for the modern world. This can be judged from its growing user base, which has already crossed the 1 billion mark. Every time there is some innovation or news of some new move from the company it garners huge interest among users.

A couple of years back, Facebook purchased WhatsApp for whopping sum of $22 billion. The app was originally a part of the growing social media but immediately after the acquisition, VoIP calling feature was added. Thus, instead of slamming the door on its competitor, Facebook used the opportunity to expand its services.


The messenger app even has internet calling facility besides the VoIP calling feature. Now, there are many other companies that would follow suit. They are going to replicate the Facebook model to enhance their businesses as well.


Businesses Are Already Using VoIP And Social Media

All leading businesses are using social media to reach out to their customers. Customers too expect quick response to their queries. All this is done with the help of social media. This gives a head-start to  IP-PBX based VoIP integration with social media.

Companies often make it mandatory to fill up a form before making their content available to customers. Now this data automatically goes into the company’s CRM or Customer Relationship Management software. Executives in the company can use the VoIP integrated with the CRM to call up new prospects or follow up with existing customers.


What Does The Future Hold For Social Media And VoIP?

According to industry data, 79% of the businesses in the US have already started to use VoIP services. Another report reveals that an equal percentage of users are using social media as well. Features like messaging will soon be integrated with VoIP. VoIP and Social Media are made for each other. The day is not far when probably we will not even be aware where and how we are using them.

Evolution of Cloud Based Phones

Evolution of Cloud Based Phones

Evolution of Cloud Based Phones

Over the years VoIP or Voice over Internet protocol has only become more efficient and user-friendly. VoIP or IP telephony is the real time transmission of voice data over the internet using the internet protocol or IP.

The Settings Behind This Technology

Three inventions primarily spurred the evolution of VoIP. First telephone, next internet and the third and most crucial invention is the internet protocol. Something that was started by Graham Bell in 1870, gained popularity over the years and turned into an indispensible part of modern communication.

During mid-1960s, internet was first time used by U.S defense, not what we use today. It was originally started by advanced Research Projects Agency Network (ARPANET). During 1980s this technology gained widespread usage.

In 1972 Dr. Vint Cerf invented internet protocol or how data transfers between two computers. Thus, the foundation for VoIP was laid until further progress took place.

Beginning of Cloud Based Phones

In 1973, again ARPANET contributed to the beginning of VoIP. It was during that period that ARPANET conducted experimental transmission. However, it was during 1995 VocalTec, an Israeli company that patented the internet phone. VocalTec developed software for transmitting the voice over internet compressed the voice signals, converted them into digital packets and distributed over internet.

As long as both the receiver and caller have same software and hardware the technology worked well. The sound quality then was nothing near the conventional phone sound, but this effort was the first step towards IP telephony that you enjoy today.

Adoption Of The Technology

The early adopters of this technology were comprised of the hobbyist who had understood the potential of this technology. They preferred transferring voice data packets over the web instead on depending upon the traditional phone system.

The software that VocalTec developed used a PC that was integrated with a sound cards and speakers and microphones. Then the system was leveraged on H.323 protocol instead of SIP protocol used today. It allowed PC users to make long distance calls. However, during 1995 the broadband internet connection was not as good as it is today. Thus, IP telephony evolved with time as there was advancement in broadband.

Development Of IP Telephony

During 1996 Intel also introduced software for internet telephone. Gradually the use of IP cloud based phones started evolving and by 1998 almost 1% of the total users of voice traffic used VoIP. Entrepreneurs started creating new hardware to support the system and software to make the system run. All this enabled phone to phone and computer to phone connections.

Even networking managers like Cisco, Lucent, 3Com started introducing hardware that will route the VoIP traffic efficiently. By 2000 the total usage increased to 3% of the voice traffic all over USA.

During the 90s for marketing VoIP costs were subsidized. However, as the broadband technology advanced, the quality of VoIP services also enhanced, there was more call clarity and reduction in latency. Cisco and other networking giants started making hardware that made this technology easier to use. It was during 1999 that session Internet protocol or SIP was released. The first open source private branch exchange software asterisk was developed by Mark Spencer.

Until 2004, mass marketing of IP telephony was not in progress. It was in 2004 when calling plans were introduced that made subscribers make calls in the same way they make call with their traditional PSTN system. Different offers were made that allowed national as well as international calling through IP telephony and with development in broadband the call quality has also developed.

What’s Next For Digital Finance?

 

The last few years have seen unprecedented changes in the way we handle our money. While on the face of it little has changed in the banking system, advances in digital technology are slowly but surely spearheading a revolution not only in the way we use our money, but the way in which we think about it. The most recent innovation to hit the market – contactless payment – may herald a new dawn in money interfacing. What could be next for digital finance?

Why Does It Matter?

Does it really matter how, precisely, we transfer our money from customer to vendor? So long as it gets from one to the other effectively, what’s the big deal? Actually, the format of your transaction – particularly the format in which you pay – does in fact have quite a large psychological impact. We’re far more likely to make big purchases using cards than we are with cash – and that’s not just because people don’t tend to carry large wads of cash around! Cash is our physical money. When we pay with cash, we can physically see our money decreasing. This is not the case with cards. It feels less like ‘real money’ when we pay for things with cards. For the same reason, payday loans and the like which can be approved over the internet frequently feel like less of a responsibility than those which you have to meet a lender face to face for – leading to a surge in irresponsible borrowing (and lending!) not so very long ago. Unsurprisingly, this psychological spending quirk is used to advantage by retailers and bankers, who want to keep us spending. However, now that we’re getting wise to the fact that card payments involve just as much ‘actual’ money as cash payments, banks and other authorities are sniffing around for new ways to make parting with money seem less painful. Contactless payment is just one way in which they’re doing this. The digital world is likely to see more and more financial innovations in the very near future.

Goodbye To Cheques, Hello To Cyber-Transfers

It’s not just the capitalist machine which requires novel ways of paying. Digital finance has made life a lot easier for many independent entrepreneurs to reach faraway customers and be paid by them very quickly indeed. Platforms like PayPal became ubiquitous extremely quickly  once their potential was realized – and as the world becomes increasingly digitized, they’re likely to go from strength to strength. If the banks don’t take them over, that is. Banks are well aware of the missed financial opportunities inherent in all of these cyber-transfers. While the money may ultimately end up in a bank account, PayPal are taking a substantial cut along the way. Banks currently remain invested in the outmoded cheque-clearing system (which gains them plentiful interest) – but this won’t be the case for long. Cheques  are being phased out in the UK in 2018 and other nations are likely to follow suit. It’s likely that the intervening years will see banks making big, PayPal-esque changes to their digital money transfer systems. Not everyone can use BACs systems to digitally transfer money, but everyone can use PayPal. Expect to see banks muscling in on PayPal’s territory by making their digital money transfer systems simpler and easier – potentially through apps and the like.

Wearable Technology

Everyone’s talking about wearable technology right now. It’s supposed to be the innovation of the future, keeping track of everything from our state of health to our social lives. We all know that a lot of confidently made future predictions get kyboshed by something completely innovative sweeping in from the left field. However, at the moment, wearable technology looks to be a reasonably safe bet so far as future digital development is concerned. The advance of contactless payment means that one need no longer be confined to a card in order to pay. Indeed, one can attach a ‘digital wallet’ interface to almost anything. Barclays are already using a ‘bPay’ system in the UK, whereby one can have one’s ‘digital wallet’ in a wristband, a fob, or a sticker which can be attached to whatever the owner pleases. Some ultimately see such interfaces being integrated into our bodies via chips etc which could be scanned. Whatever the ultimate destination of this technology, it seems pretty clear that the way in which we pay for things is about to change rather drastically!
