It is also worthy to note that Accelerators do not actually use lossy compression schemes that might degrade voice quality and they add less than one millisecond of latency. In fact, the Accelerator’s compression actually reduces end-to-end latency by reducing serialization delays on WAN links. For example, it takes 125 ms to serialize a 1,000 byte packet on a 64 kbps link, but if an Accelerator increases the effective bandwidth by 4X to 256 kbps, the serialization delay is reduced by a factor of four to 31 ms. The following formula can be used to calculate the serialization delay for any combination of packet size and link speed:

Packet Size (in bytes) x 8 / Speed (in kbps) = Serialization Delay (in ms)

In addition to freeing up the bandwidth normally consumed by data applications, Accelerators are able to reduce WAN bandwidth requirements for different voip codecs. In fact, tests have shown that Accelerators reduced G.711 bandwidth requirements by 20% and G.729 by 70%. As a result, WAN links can carry more simultaneous voice calls and the performance of other applications may also be improved.

Accelerators solve increased jitter and latency caused by large data packets over slow WAN links by fragmenting large data packets and injecting voip packets at regular intervals. This feature allows voip and data to co-exist even on branch office WAN links. For example, normally, a voice over IP packet “stuck” behind a 1,500 byte packet on a 64kbps lin will be delayed by 188ms.

Using the Accelerator’s packet fragmentation will result in the data packet being reduced in size (accelerated - say from 1500 bytes to 500b bytes) and then fragmented into smaller data packets (say - 2 packets of 250 bytes each). In this case, the latency for the voip packet will go down from 188 ms to 31ms! In addition to increasing WAN capacity for both data and voip while reducing latency and jitter, Accelerators also manage WAN bandwidth to ensure that critical applications like voip get the bandwidth they need.

Accelerators include an Instant QoS feature that prioritizes application access to WAN bandwidth. Without such priorization, the additional effective bandwidth provided by Accelerators could be consumed by aggressive, non-critical applications such as file sharing. Accelerator’s AppView feature provides graphical visibility for all application traffic sharing a link. AppView can be used to monitor WAN utilization and to plan future capacity requirements.

And finally, voip accelerators have a set of data integrity features that are designed to stop the packet loss that can degrade voice quality. A flow control mechanism reduces packet loss caused by link congestion and a packet recovery feature ensures that any lost packets are transparently recovered at the link level before they can cause voice quality problems.

The primary goal of market research is to gain understanding and insight on a particular market it wishes to explore. It means gathering data on the market participants. This includes data on the business producers and their products, the government regulatory agencies, the end-consumers, as well as other agents which could influence the dynamics of that market. Market research analysis then would process these different inputs and provide a business customer with actionable information which could be a competitive advantage to him.

Market research analysis has gone through various changes based on advancement in communication technology. The earlier form of marketing was simply personal interviews or group interviews to analyze the qualitative and quantitative data of a particular product to be offered. However, the advancement in latest technology such as conference call has opened a cost effective and efficient alternative of market research.

For making conference calls, market researchers place calls to different people from various backgrounds and places and invite them to join a telephonic conference. Joining conference calls is attractive for the participants as it saves them the time and effort of attending a real life discussion/conference for market research. Market researchers can leverage conference calls to tap busy resource persons who would otherwise be too busy to attend a real life discussion for market research purposes.

One more thing, also making conference calls will allow the market researcher to obtain fast feedback on market issues that is important to business customer. This immediate accessible information and its own analysis could allow its business customer to move itself in the market and gain additional revenues and profit.

Generating revenue and sustaining profitability are the important concerns of any modern business. A quick and effective market survey will enable business houses to respond to the needs and expectations of the customer by providing a good product. Such a market survey will also help to keep the copetitors at bay and also please the public and the state as a good corporaate citizen.

customers are given the means of getting immediate beneficial information on particular market issues or indicators through the conference call services offered by market research companies. Marketing research done this way saves on cost, thus proven a much more appealing option compared to other ways of doing research.

Market research provides information on the market, which can be used for product launches and customer needs fulfillment. Data for market research analysis can be captured from one-on-one interviews over conference calls with target customers. This reduces the cost involved in collecting quantitative and qualitative data, while allowing all to interact in a forum or discussion. Also, it saves time and effort allowing otherwise busy people to be present at the venue.

A newer, but still equally vital, communications channel is the Internet. Developed in the second half of the 20th century, its usage has caught wildfire in the last couple of years, effectively breaking some of the long-held traditions of doing things. E-mails and instant messaging (or chatting) are used by top-level executives and rank and file employees. The Internet is also heavily used for sharing files, research, on-line shopping, and entertainment purposes.

Its primary purpose, however, is still communication. A few years ago, the Internet-based phone service called Voice over Internet Protocol (VoIP) became a huge thing in the market. Considered a breakthrough in the communications technology, it has since won over subscribers and customers looking for an affordable way of connecting with friends and family, and of conducting business. Some people have even cut their telephone lines and shifted to VoIP.

VoIP is popular because it works just like your conventional telephone. However, VOIP relies on the Internet to transmit and receive audio data, in the process converting your voice digital audio data. This means that you will receive and transmit clearer digital audio data at a much faster rate.

The fact that it uses the Internet to transfer and receive digital data, makes VOIP calls much cheaper than the conventional landline phone calls. With the landline phone, a five-minute call can cost a lot of money. Internet voice calls of the same duration costs a fraction of the landline charges. Some VoIP providers even offer free long distance and overseas call.

Besides free phone calls, VOIP Providers usually throw in extra phone features, such as three-way calling, caller ID, audio conferencing, video conferencing, call waiting and return call, in the package. Traditional phone companies also offer these services, albeit, with extra cost.

This is why many VoIP service providers today are now offering a trial period, usually 30 days, for clients to test the quality of their services. If you are not satisfied with their services, you can simply inform your service provider that you are no longer interested in using their services. If you do this within the trial period, you will be refunded.

With many providers offering a trial period (usually 30 days), you may now test the quality of their services. If you are not satisfied, you can simply inform the company that you are no longer interested to use their services. If you do this within the trial period, you will be refunded.

Here are some things that can guide you in choosing the right provider. Look for one that offers maximum benefits to their clients, including free ATA (Analog Telephone Adapter), free or low cost IP phones, among other things.

For the best outcomes, choose the company trusted by your community. You can confer with your friends, colleagues to find out which service provider offers the best ones.

One of the chief attributes of VoIP that is discussed the most is the lower long distance and overseas call fees. Those fees can really add up particularly if you make a lot of calls for your business and many VOIP carriers provide attractive long distance rates.

Cheaper distance and overseas phone calls are a chief advantage of VOIP, but they’re not the only advantage, by far.

An area where VoIP has a real advantage is that most home VOIP providers often let you use your existing phones. You won’t need to buy a new phone, as you do when changing cell phone providers. This may not be a key consideration for everyone, but it is important to think about how you’ll be using your VOIP telephone
service and to take into consideration the usefulness of keeping your telephones.

If you run a business from home, and receive a lot of calls, you’ll enjoy the voicemail features many VoIP service providers offer. Many of them will email you when you receive a voicemail message and allow you to retrieve your messages online. This is a useful feature for those of us who can’t always answer the phone. It allows us to quickly check our messages without interrupting our work flow.

An often heard question prospective VOIP users ask is, “How’s the sound quality?” This is a sensible question and an important one. Since VoIP is a new technology, the very idea of sending voice over the Internet raises some questions about how it works. Most VoIP service providers connections have excellent sound quality. Businesses have been using VOIP for quite some time now and continue to use it – so the sound has to be good.

Fortunately, the sound quality of the VOIP telephone does not seem to degrade when used in the home and the majority of residential VoIP customers are content with the quality of their phone calls.

Finally, VOIP offers a wide choice in VoIP service providers, which is very significant to a lot of people who have been disgruntled with the level of service and support (or lack there of) offered by their current telephone company.

While the smaller, friendlier phone companies are now offering a residential service, many VOIP users switch to VoIP service providers in part so that they could work with a different phone company and avoid the bother their analog phone provider caused.

VOIP is a fantastic choice for many home phone users because of the cost savings, ability to use your own phone, call features and sound quality. Plus many people find working with more supportive companies much less of a chore.

Overall, it is clear that there are many positive aspects of a VoIP residential phone service. At the beginning of 2007 it is reported that 9% of households in the US use VOIP, and at the current uptake rate there will be 27 millions users by 2009.

A popular technology that has been transforming the Telecommunication Industry and is set to dominate the Internet Services market is voice over internet protocol (VoIP).

With this amazing technology it is possible to make unlimited free local and international phone calls.

So what exactly is all the hype about VoIP?

Voice Over Internet Protocol offers a simple way to make Internet phone call using any Internet connection. 10 years ago no one would have imagined that Internet phone calls would become so easy and cost-efficient! Now there are millions of users all over the world making free long distance calls using popular, free voip services and software.

Free pc to phone calling is really a revolutionary step in the history of Internet innovations.

First Release of VoIP Geochronology

First releases of VoIP meant users had to download software, also known as soft phones or sip phones and install it on a computer. If two users wanted to make free internet phone calls they had to be at their computers, listen through headsets and talk via microphones. Today voip technology has improved to the point where free local and international phone calls can be made using traditional landlines and mobile phones without the use of personal computers and software.

Many of us have heard of Skype, they were early pioneers of voip technology, it is estimated that at one point Skype had over 30 million registered users. Since those early days many other voip service providers have joined the market, including all of the big traditional telephone service providers such as AT&T and many others all over the world. These established companies were, in the main, slow to adopt the emerging technology.

Changing Landscape of Telecommunication Industry

In the past, Telecommunication services were provided either by Government bodies or large multinational companies due of the huge investment in infrastructure required to provide these services. With the internet and voip technology it is now possible for a small one-man operation to provide online services offering free phone calls to anyone, anywhere in the world.

Who is paying for your free phone calls?

As the saying goes “no such thing as a free lunch” this also applies to free Internet phone calls. In order to use voip a user must have an Internet connection and this, in most cases, have to be paid for.

Most voip providers offering free phone calls will impose some limitation on the amount of free time customers can use, commonly referred to as “fair usage policy”, before they are charged for the service. Other restrictions may also apply in the way free phone calls are used; such as restricting calls only to other users in the same network or restricting free calls to certain countries.

As well as the restrictions noted here, some providers are charging advertisers and sponsors for advertisements which are then played to users before they can actually make free phone calls in the network.

However, when the service ceases to be free, the amount charged are extremely low rates compared to tradition telephone rates and especially so when compared to mobile phone rates.

How You Can Make Free Phone Calls

For those who are familiar with computers and are prepared to download and setup the software themselves, free phone calls are definitely possible. All you need is the computer, software and a gateway from a service provider, the person you want to call also need to have the same compatible setup on their computer.

A Voice over IP device can be classified in three general categories:
- end stations (such as phones),
- gateways and routers,
- and controllers.

Like everything else in IT, every category has a specific function that it performs. And if you combine all the functions you will get a complete Internet Telephony system.

Hardware and software VoIP phones
There are two types of VoIP phones: hardware and software.
- A <B>hardware phone</B> is a physical device, very similar to your common phone; it has a handset, dialpad, etc. The only thing that is different from your ordinary phone is that it connects to an Ethernet network rather than a telephone network. IP phones are built with all the necessary hardware (and software) to digitize your voice (i.e., codecs) as well as setup and make calls (i.e., signaling and transport).
- <B>Software-only phones</B>, or “soft” phones, use the PC’s capabilities to communicate with other PC’s over the Internet, by using the PC’s sound card, CPU and network card as part of the phone’s hardware, and thus, enable a PC to become an IP phone.

Internet Telephony Controllers
VoIP controllers, also called IP PBXs, manage the VoIP network. They are actually tools that you can use to configure your IP phone: restrict access, enabling functions and passwords, allowing/not allowing certain options, etc. Plus they are performing all the functions of a traditional PBX. IP PBX controllers are PC-based, running a standard OS (such as Microsoft Windows, Linux or Sun Solaris, but very different) with additional software to control the Internet Telephony systems. These Internet Telephony systems can provide APIs to extend vendor-provided or user-written features and functionality.

Voip Routers
Voip Routers are devices that decide where the IP datagrams should go, between networks, from the source to the destination. Voip Routers are inter-network equipments that help a LAN connect to a WAN; therefore the router’s capability to ensure correctly handled high-priority traffic is very important. Since WAN speeds have generally less bandwidth than a LAN, proper packet queuing and prioritization is in order to ensure good voice quality across the path.

Gateway
A IP-telephony device is a device that connects the VoIP network to your public telephone network (PSTN). In this way, you can make calls and receive them, from your PTSN, even if you are using an IP-based system, just like your traditional phone. Depending on the type of the gateway, they are equipped with analog/digital interfaces in order to connect to your local telephone company. With so many options available today, gateways are also capable of transcoding (changing the signal from one codec version to another so that the Voice over IP device can communicate with the rest of the network). For example, a gateway uses G.729 codec, while your PTSN network uses a G.711 codec.
