Residential VOIP

Will VoIP be a Mass Market Product?


A common thinking among "Marketing people " is that for every product that enters the market there must be a path, a target, a need ( real or created) that decides how the product must enter the consumer's life, which part of the population is more likely to go for it, which niche it is going to fill and, most important "...certain things being stated, something other than what is stated follows of necessity from their being so." and that is the final issue: the price.


Depending on those anavoidable patterns a product is more or less ready for a certain market.


High technologically devices, the ones that offer perfect quality and cost a fortune will target the elitarian
market, where the price has not big importance (on the contrary, if the price would be lower than what
certain people can afford, the product wouldn't reach them) since it means luxury.


When a product ceases to be luxury and begins to be a need, then the mass market is ready. The product
can enter 60% of consumers' lives, reach easily a good upgrade in the percentage and become " The New
Product of the year 200....".


Let's consider the VoIP market.


Prior to recent theoretical work on social needs, the usual purpose of a product invoked individual (social)
behaviors. We now know that these assumptions are not completely wrong.


Wrong would be NON considering them.


In systems where many people are free to choose between many options, a small subset of the whole offer will get a disproportionate amount of traffic (or attention, or income), even if no one of the system actively work towards such an outcome. This has nothing to do with moral weakness, selling out, or any other psychological explanation. The very act of choosing, spread widely enough and freely enough, creates a power law distribution.


Now, thanks to a series of breakthroughs in network theory by researchers we know that power law distributions tend to arise in social systems where many people express their preferences among many options. We also know that as the number of options rise, the curve becomes more extreme. This is a counter-intuitive finding - most of us would expect a rising number of choices to flatten the curve, but in fact, increasing the size of the system increases the gap between the #1 spot and the median spot.


In other words: give to the people the choice among desktop phones and mobile phones and the majority will choose what they think more convenient, in spite of the cost of the service.


In a way the cost of the service is the only left advantage in favour of the fixed telephony.


If the price was the same the desktop phones would disappear from the life of the average consumer (mass market consumer).


To see how freedom of choice could create such unequal distributions, consider a hypothetical population of a thousand people, each picking their favorite way of telecommunication. One way to model such a system is simply to assume that each person has an equal chance of liking each kind of telephony. This distribution would be basically flat - most kind of telephony will have the same number of people listing it as a favorite. A few will be more popular than average and a few less, of course, but that will be statistical noise. The bulk of the telephony will be of average popularity, and the highs and lows will not be too far different from this average. In this model, neither the quality of the voice, the availability, the design of the device nor other people's choices have any effect; there are no shared tastes, no preferred genres, no effects from marketing or recommendations from friends.


This is the mass market of VoIP as dreamed and forecasted by most hardware producers.


People would choose VoIP in spite of the fact that the systems are not intercommunicating, the available phones are just desktop phones, most of the population doesn't have a "Flat rate DSL" and some do not even have a decent connection, (just one " UP to...) and just because VoIP means cutting cost.


They have a few wrong assumptions:


1. Most of the people want to save calling internationally
2. Most of the people will use a cheap Flat rate connection
3. Most of the people know how to handle a computer or a network, and so solve all the eventual problems that could arise.


But they do not consider that:


1. Most people call locally and just a few once in a while internationally.
2. Most of the people do not have a cheap flat rate Internet
3. Most of the people are not IT experts.


Besides people's choices do affect one another. If we assume that any kind of telephony chosen by one user is more likely, by even a fractional amount, to be chosen by another user, the system changes dramatically.


If Robert (our average mass market consumer) likes to have a phone in his pocket, available mostly anywhere, it is very likely that Mary would like the same.


Is VoIp ready for the "Mass Market"?


The answer could be No and Yes.


What would VoIP offer more than the existing several choices?


1. Price. Telephone calls would be completely free of charge among two IP phones ( and that believe me is a GREEEEAT THING when you try it)
2. The never enough considered satisfaction to be able to ref..ck who f..cked us for many years...


What would VoIP telephony need to be #1 spot in the curve?


1. A reliable PORTABLE Phone that doesn't need millions of Hot Spot's to work.
2. A reliable, cheap flat rate internet connection anywhere for everybody.


If ONE could put these patterns together, THEN VoIP would really have the chance to be #1.

Challenges in VOIP

How to choose VoIP service without losing your shirt

Just mentioning the word to yourself either brings up images of walking in a new city where the grass is greener, or it brings up fear of the unknown. Some will tread carefully around the subject, waiting to hear others opinions about a specific service and some may charge fearlessly into a service that they know little about. Which way is the right way to choose a VoIP service? I say neither.


Is there a safe way to choose a VoIP service? You bet there is, but it does take some work and careful
research to make sure that you don't get stuck with something you cannot use or worse yet, be forced
into a scenario in which your telephone communications is impaired.


There are 3 general steps to choosing Broadband Phone service. They are:
1.Qualify Yourself
2.Qualify a specific Provider, and
3.Research the provider.


1.Qualify Yourself – Ask yourself “why do I want voip?” Is it because you want to save money? are you
attracted to voip by all of the features that it offers? Maybe you're sick of your local telephone company.
Whatever the reason, make sure that the benefits are better than what you're already getting now. For
instance, you might want to save money on long distance with a voip provider but don't want to give up
your old phone number. In this case you would have to ask yourself whether it would be acceptable to
lose your old phone number to save a few extra dollars. These days, most providers (but not all) will allow
you to keep your old phone number. Do you have a secondary means of communication such as a cell
phone?


When your internet connection goes down, so does your voip line. That means that if a large storm knocks out power to your house, then your internet connection will also most likely be down. Another thing to consider when qualifying yourself for voip service is that 911 service is not as robust as a land line service would be. You may have to give the dispatcher your name and address. The good news is that the larger providers are working with the dispatchers to provide 911 service that is just as robust as 911 on a land line.


Last but not least you must make sure that your your internet connection is suitable for voip. Sorry 56k'ers but dialup just isn't gonna cut it for voip. If you do have a broadband connection, head on down to http://www.testyourvoip.com and do a quick test.


2.Qualify a Specific Provider
Your voip provider means everything when it comes to reliability and sound quality. You should choose a provider that has the features that you need (call waiting, 3 way calling, extra lines, distinctive ring, etc.). One thing to definitely look into is the 911 service that's offered and don't be afraid to ask lots of questions to the customer service department of the prospective provider. Number portability (if you need to keep your old number) is something else to be looked into. The rates should be competitive and don't forget to look at international rates if you do any international calling. The most important thing to look for in a voip provider is a money back guarantee. If there is no money back guarantee, then pass on that provider; just about all voip companies have a guarantee.


3.Research the provider
Just because everything looks OK from a customer service angle, the service is cheap , and does what you need it to does not necessarily make it a good service. What does make a service good is if they have happy customers. The best way to do this would be to search the better business bureau for complaints against the company, search google with something like reviews, complaints, opinions, etc. author : Jason Stewart

VOIP Phone Systems

Is VoIP only beneficial for corporations?

Generally, telephone service via residential VoIP is either free or costs less than similar service from traditional sources, but it's comparable to alternative Public Switched Telephone Network (PSTN) service providers. Some cost savings are from using a single network to convey voice and data, especially where users have accessible underutilized network facility they can use for residential VoIP at no extra cost. VoIP to VoIP telephone calls on any given provider are customarily free, while VoIP to PSTN calls normally costs the user of residential VoIP.


VoIP technology does not quite require broadband Internet access, but this normally sustains improved
quality of service. A considerable percentage of homes today are connected to the Internet through DSL,
which requires a traditional landline telephone line. Having to pay for provider residential VoIP as well as
both a basic landline telephone line and broadband Internet access minimizes the probable benefits
of VoIP. However, some regional telephone companies now offer DSL service without the telephone,
consequently saving subscribers money when they switch to provider residential VoIP. VoIP can also be
used with Cable Internet instead of DSL, which can eliminate the need for a traditional telephone line
completely.


Some broadband connections may have below looked-for quality. Where IP packets are lost or delayed
at any point in the network between residential service VoIP users, there will be a momentary drop-out
of voice. Technology has improved the reliability and voice quality over time and will continue to improve
residential service VoIP performance as time goes on.
Issues with enterprise IP telephony
Although only a small number of office environments use a pure VoIP infrastructure, telecommunications
providers regularly use IP telephony. This is often used over a devoted IP network, to connect switching
stations, as it converts voice signals to IP packets and back. The aftermath is a data-abstracted digital network which the provider can upgrade and utilize for multiple purposes.


Corporate customer telephone support often uses IP telephony strictly to take advantage of the data abstraction. The benefit of using this technology is the d esire for only one class of circuit connection and better bandwidth usage. Companies can acquire their own gateways to abolish third-party costs, which is worthwhile in some instances.


VoIP is widely employed by its carriers, chiefly for international telephone calls. It is regularly used to direct traffic starting and ending at conventional PSTN telephones.


IP packets are sometimes lost or delayed at any point in the network between VoIP users. This usually results in a temporary drop-out of voice. It is more noticeable in severely-congested networks and where there are long distances as well as inter-working between end points, such as in corporations.
Requirements for home users and corporations
A major development starting in 2004 has been the introduction of residential VoIP services over broadband enterprise service VoIP, in which subscribers make and receive calls as they would over the PSTN. Full phone residential VoIP service telephone companies usually provide inbound and out bound calling with Direct Inbound Dialing. A popular offer is unlimited calling in the U.S. and Canada as well as selected regions in Europe and Asia for an even monthly fee.


These services take a wide array of forms which can be more or less similar to traditional Plain Old Telephone System (POTS). At one extreme, an analog telephone adapter (ATA) may be connected to the residential VoIP service and an existing telephone jack in order to provide service nearly identical from POTS on all the other jacks in the residence. This type of service, which is fixed to a single location, is simply offered by broadband Internet providers like cable companies and telephone companies as a cheaper flat-rate traditional phone service.


Often the phrase "VoIP" is not used in peddling these services, but instead the industry has marketed the phrase "Internet Phone" or "Digital Phone", which is aimed at average phone users who are not really tech-savvy. In the corporate workplace, broadband enterprise service VoIP generally uses the term "Internet Phone". Typically, the provider publicizes the advantage of being able to keep the existing phone number. Examples of this type of service in the United States are not limited to Time Warner, Comcast's Digital Phone, Verizon VoiceWing and AT&T CallVantage.


An advantage of Vonage or BroadVoice broadband enterprise service VoIP is the ability to make and receive calls as one would at home, anywhere in the world, at no extra cost. No additional charges are incurred and the called party does not have to even pay for the call. For example, if a subscriber with a home telephone number in a U.S. area code calls another individual in his home area code, it will be treated as a local call no matter where that person is in the world.
