6. T / F Peer-to-peer (P2P) networks are perfectly safe to use, especially if your computer is protected with firewalls.

Answers

1. The answer is True. In fact, it is the tremendous savings of up to 80% off traditional phone calling that makes VoIP attractive to consumers and businesses. The only equipment needed for VoIP is your PC and a microphone (if one is not built into your PC). Beware of VoIP service providers that require you to purchase additional equipment and/or sign contracts.

2. The answer is False. Although the public has been fed a steady diet that the minimum requirement for VoIP is a high speed (broadband) connection, this is absolutely false.

Over 90% of the VoIP providers have used this false premise as a smokescreen to take your focus off the fact that their priority was and is to line their own pockets rather than expend the time, effort, and funds to develop technology that incorporates dial up capability.

The technology required for dial up connections to use VoIP involves the ability to compress data packets down to a minimum size of 8 kbps prior to traveling over the Internet.

3. The answer is False. Security should be the most important feature of any VoIP solution provider. Firewalls do not incorporate protection for VoIP. VoIP security should incorporate protection against identity theft, Trojan horses, viruses, and worms.

Craig Pollard of Siemens advised that “Voice must be protected like any other application'. He further stated that, 'Along with IT directors and telecom managers, a number of financial directors came to our road shows, which may not be surprising considering the damaging potential of VoIP threats if a network is not properly protected.'

Over 90% of VoIP solution providers do not operate on secure lines. These providers, in order to save a few dollars at your expense, operate on industry standard codec (encryption codes) and industry standard protocols which are publicly open and interpretable. Hacker friendly providers offer hacker manuals, software, programs, and even processor chips that makes accessibility to your computer from these industry standards – as enticing as chum is to sharks in a feeding frenzy.

When a computer hacker gains unauthorized access to your computer, their sole purpose is to steal your identity and sell your personal and confidential information to other criminal entities. In addition, they often plant Trojan horses, viruses, and worms into your computer.

4. The answer is True. Industry insiders such AT&T says, “VoIP traffic is projected to account for approximately 75% of the world’s voice traffic by 2007”. This suggests a major paradigm shift in communication.

5. The answer is True. Not only can you make all your phone calls anywhere in the world from your computer, you can also travel with your computer phone. Simply by bringing your unique number and password, you can download your phone with your entire contact list. Of course, PC to PC is usually free between subscribers. PC to telephones and cell phones typically involves fees at drastically reduced rates when compared to traditional calling rates.

6. The answer is False. P2P networks use industry standard codec (encryption codes) and industry standard protocols which are publicly open and interpretable.

John Ashcroft, Attorney General, in remarks at the High Technology Crime Investigation Association 2004 International Training Conference held on September 13, 2004 stated, “We have seen worms and viruses attack…disrupting basic services…And with the increased use of the Internet and especially peer-to-peer networking, we have seen malicious code spread more quickly and infect more personal computers than ever before. The cost of these worms, viruses, and denial-of-service attacks…reaches into the billions of dollars.”

P2P networks such as Skype operate by taking bandwidth (information carrying capacity) from customers on their service to assist other customers using their service - analogous to a symbiotic relationship. The tools that enable them to accomplish this are bundled in the software their customers agree to in order to download and access their VoIP service.

Another grave concern for both individuals and businesses when using P2P systems is unknowingly having your computer used as a supernode. A supernode occurs when your computer is arbitrarily assigned as a hub.

When you are running the software for P2P services, your computer’s disk space, bandwidth, and processing power are used to help other users on the same system operate their software more efficiently because of their own network or firewall constraints.

We as consumers still have a lot to learn about VoIP, as this technology is the new era of communication and is continuously being changed.

All VoIP service providers need to incorporate the protection, needs, and desires of its customers, as well as address security and dial up capability.

All VoIP service providers should invest in developing a proprietary patented technology that incorporates compression of data packets so that their VoIP can be used on dial up connections, as well as cable, satellite, and wireless.

All VoIP service providers should develop and create their own proprietary high end encryption codec with patented technology, simply because they do not want their customers to be victims of viruses, worms, Trojan horses, or have their identity stolen as a result of using their VoIP service.

Simply put, all VoIP service providers should place the protection, security, and needs of their customers FIRST. Of course, they are in business to earn profits, but it should not be at the expense of exposing their customers to unscrupulous entities.

What is an Avaya Media Server?
A Media Server forms the backbone of a flexible communications system for growing companies. It allows your company to take advantage of the increased functionality of an IP network without replacing your existing infrastructure.

What does a Media Server do?
Media Servers work in conjunction with Media Gateways to provide a streamlined voice and data network throughout your entire enterprise. Media Servers and Gateways provide a network built on an industry- standard operating system that supports distributed IP networking and centralized call processing.

What is the relationship between Media Servers and Media Gateways?
A Media Server works by controlling the Gateway; the Gateway allows branch offices to connect to the network, and the Server powers the network.

Can Media Servers power more than one Gateway?
Absolutely. The total number depends on the model, but Media Servers can support several Gateways, expanding with complete ease. In fact, the S8700 can support up to 8,000 Media Gateways, offering up to 36,000 stations.

Can any Media Gateway work with any Media Server?
The S8300 Media Server only supports the G700 and G350 Media Gateways, but both the S8500 and S8700 Media Servers support all Gateways. Both the G700 and G350 Media Gateways are compatible with every Media Server.

What are the benefits of installing a Media Server?
The immediate benefits are increased productivity, efficiency, and savings across the entire enterprise. The branch office has access to the same features and applications as the central office, and the Media Server consolidates multiple systems into a single server, enabling you to manage the entire communications infrastructure from one location.

What size of businesses can use Media Servers?
One of the hallmarks of Avaya Phone Systems products is scalability; Media Servers can function as a single unit powering a single office, and Media Servers can support an entire global enterprise.

It is no secret that communication is key to survival for small business. The advantage to small busineses of using a VoIP solution is that the market is very competitive. While there are relatively few companies from which to choose for normal phone service, many VoIP providers will gladly offer VoIP phone service at a very competitive rate and with unlimited long distance.

But....you need to do your homework first.

Phone service features indispensable to your business, such as voicemail, conferencing and call waiting, allow business to flow smoothly and efficiently. So....how do you decide if a VoIP solution is best for your business?

One of the first steps when analyzing your current service is to decide what features your business needs. Does it need multiple lines to accommodate the sales force? What about a toll free number for customer service? Make a list of all the features your office uses and think about others you might want to try.

The next step is to make an estimate of all intrastate (in- state), interstate (state-to-state) and international calls. An easy way to estimate these numbers is to view a recent phone bill. You might be surprised at how large or small your call volume actually is. If you rely heavily on fax machines, consider the number of incoming and outgoing faxes. As you review these numbers, remember to consult growth projections for the rest of the year.

Once you've done all this...you're ready to go comparison shopping.

Here's some resources to help you do that:

* VoIP Comparison Reviews

VoIPReview does a good job comparing feature sets from each of the providers. Its user reviews seem a bit skewed, but otherwise the site looks good.

* ZDNet Reviews

ZDNet usually has objective reviews. Read through its commentary on any of the providers you are considering.

* Broadband Reports

Broadband reports has a specific area for review by users...with a regularly updated scoring system. It's often skewed with a tad bit of emotion....and reviews are mostly residential. But it does give you an idea for business use.

* Google

I'm sure most of you already do this, but once you've figured out what you're looking for, perform a search on companies on Google to see what others have said about it.

If you're willing to do a bit more work, contact various providers and create your own comparison chart. You can begin your research by visiting voipreview.org. The site offers VoIP facts and reviews of various broadband phone service providers. Compare the business plans for different providers and research the various features offered with each plan. Also, make sure your current Internet connection can handle VoIP calls. The Web site testyourvoip.com will evaluate and score your Internet connection. You'll know if it makes sense to run your phone traffic over your broadband connection.

Circuits on an IP network can carry more traffic than circuits on a TDM network. Strategically, it costs significantly less to deliver calls over IP than it does TDM. The laws of economics are driving us inexorably towards VoIP. However there are a number of other benefits that are specifically useful for businesses.

TDM technology has evolved over a century and was primarily developed at the behest of the old nationalised post, telegraph and telephone companies (PTTs) such as the UK’s GPO before it became BT. Therefore the TDM network is rigorously engineered and very robust. We take it for granted that when we pick up a phone and punch a dozen or so buttons, another phone will ring just about anywhere in the world. When that phone is answered, we (normally) have a clear and uninterrupted conversation. This is not surprising given that multiple layers of switches and wires between the two phones create a complete end-to-end 56Kbps circuit between them.

In the modern, highly flexible and mobile work space this marvel of technology has one drawback. You don’t call a person, you call a phone. Therefore, you assume that the person you want to talk to is going to be close enough to that phone to answer it, or has put a machine in place to take you call, or is willing to pay extra for it to be forwarded to another device. Meanwhile, in an IP world, you connect to the network from any IP device and if you are connected to the internet, then the Internet can tell those trying to reach you where you are. VoIP will allow you to call a person, not a phone.

The other drawback of the TDM connection is that the circuit has a fixed bandwidth that was originally designed to support a phone conversation and nothing else. Dial up data communications and fax technology are essentially technical compromises. Anyone who struggled to surf the web over a dial up connection will recognise this. The essential technical difference between IP and TDM technology ensures that a VoIP conversation makes better use of that bandwidth. Furthermore, with the ubiquitous availability of DSL, the Internet is now a multi-megabit, broadband network that breaks free of the 56 kilobit shackles of the TDM network. The result is that we can have far “richer” conversations with IP.

These conversations can include video images, instant messages and data – all over the same circuit. Voice over IP is but one application on this converged communications platform. Ebay’s acquisition of Skype is a good example of the creation a converged applications. Ebay is an on-line auction house that provides its bidders images and data about items for sale as well as conducting the auction over the web. Skype is an internet telephony service. Combined, the two businesses will offer a service whereby someone bidding for a particular item can click a button on the screen and talk directly to the person offering the item for sale. It does not take too much imagination to envisage similar applications driving improved efficiency and productivity across all shapes and size of business.

In summary, the three key advantages of VoIP over IP versus TDM are cost, flexibility and better, richer ways of communicating.

Imagine phones (that look like regular phones as we-know-it-today) connecting to the Internet via an Ethernet jack (similar to a PC) instead of the phone plug on the wall. These are called IP-based phones. These phones do not use analog phone lines - instead they get connected to the Internet. One would pick up the receiver and make a phone call just as it is done today and VoIP converts the human voice into IP packets (data similar to email data) and pushes it out through the Internet to the phone switch where it is terminated. In a nut shell, VoIP digitalizes voice into data packets, sending them and reconverting them back into voice at destination.

What are the benefits of VoIP and why you should consider it? To compete effectively in the eWorld, a decent businesses infrastructure MUST HAVE two essential components: A High-speed Internet connection and a sophisticated phone system.

Up until now, to build a solid infrastructure, small businesses had to spend lots of money for having multiple phone lines, perhaps an 800 line, fax line, credit card machine, to name a few. These days the ONLY essential component to worry about is having a reliable high-speed Internet connection. Connectivity can be addressed with either cable or DSL service (typically $250 per month) through cable providers such as Comcast, RCN, etc. and DSL can be provided through the Verizons of the world. The good news is that with the arrival of VoIP, there is no need to pay a dime for multiple phone lines, any phone system (PBX), any local/long distance calls, phone maintenance, etc. At 30% to 50% less than the cost of a typical phone system, a VoIP system will provide a more sophisticated system with increased functionality than any analog phone system. It offers an enterprise-level system that was affordable ONLY by fortune 500 companies. Now small businesses can compete like big corporations at a fraction of the cost!

Small businesses are beginning to realize that IP-based phone system streamlines their communications needs and their call flow in ways that was not possible a year ago. As a result they can improve the customer experience and combined with wireless IP communications, employees can become completely mobile. The beauty of it is that IP enables the phone to be anywhere – this is a perfect solution for companies with remote/satellite offices who wish to have one uniform phone system for all employees regardless of their location.

There's a whole list of benefits unlocked by VoIP beyond the obvious. One of the most important advantages of using VoIP is reliable continuity. Imagine having a system that can stay operational through the Sept. 11 attacks in New York, or the August blackout and a whole list of building failures by the central phone system. In a typical VoIP system the main elements of the network are offsite, they're automatically protected from these sort of issues. Another benefit is, unlike a traditional phone system [Time-Division Multiplexed TDM], where the environment is a common point of failure, in a VoIP it is very easy to put in redundancy in which all clients connect to the outside world by more than one path. This guarantees phone connectivity and no call is ever lost.

IP telephony lowers the costs of communications system tremendously while increases productivity in more ways than one. Consider a world where ALL communications, including eMail, voice messages, conference calls, and/or even wireless devices can be integrated through a single system where employees, no matter of the location, can be contacted. For companies with multiple locations, VoIP system can eliminate the need for several receptionists – which is growing in popularity.

The benefits of VoIP are endless. It eliminates the need for having an expensive PBX system; it saves time and resources associated with the maintenance & supporting such systems; it removes the hassle of dealing with phone companies; on and on … while offering a superior phone system at 30 to 50% of the cost.
