VoIP is a great way to communicate with family and friends at a very low price. However, there are a variety of hindrances with switching to VoIP. This article goes over many of the disadvantages of VoIP, which may have experienced. Additionally, this article will explain how you can improve the quality of VoIP phone service.
Disadvantages of VoIP
Although there are many advantages of VoIP, there are also quite a few disadvantages. Below are four of the most common disadvantages of VoIP.
1. Maintaining a Dependable VoIP Internet Connection
If for any reason, you lose your internet connection, you will not have phone service. Therefore, you must use a cellular phone should this type of situation arise.
2. 911 Access
When you place a 911 call, the location cannot be immediately determined. Unlike PSTN, you must register your phone number online so that should you need to make a 911 call from your VoIP, emergency services will know your location.
3. Networks Have a Large Number of Computers Connected
If your network has a large quantity of computers connected and they are all using the internet at the same time, your VoIP quality will generally be less than desirable. One way to avoid this situation is to invest in an Ethernet.
4. VoIP Poor Quality
Audio quality is one of the largest issues. No matter what your VoIP service offers you, the basic role of any phone is voice communication. If the quality is not up to par, then there is absolutely no point to all of the bells and whistles that come with the service. If you have a lot of background noise, then a VoIP that can handle music, video, caller ID and a variety of other advanced features is practically useless. In the next section, we will address this issue more thoroughly.
Even with all of the advancements of VoIP, there are times when the audio quality suffers. Since VoIP relies completely on the internet connection, anytime the internet suffers so will the VoIP.
Six Ways to Improve the Quality of VoIP
Poor audio quality (disadvantage #4) along with dropped calls, are all complaints that user of VoIP tend to make. Below are six ways the setup of your VoIP can affect the overall quality. By following these simple steps, you can easily improve the quality of your VoIP service.
1. Internet Connection
One of the first recommendations is a high speed internet connection. There are companies which offer VoIP for dial up users. However, the connection can result in poor audio quality. Eventually, you will grow to dislike your VoIP. However, it is not the VoIP, but rather the internet connection. Even if you have DSL, there are occasions when the connection may be slow and your VoIP quality will suffer. Therefore, an Ethernet connection is highly recommended.
2. External Factors
Weather conditions, such as thunder storms, heavy rains and snowstorms can all can an increase in static on broadband lines. In some instances, simply turning rebooting the VoIP can solve the problem. Another solution to reduce the static is for the VoIP service provider to replace the cables with a higher quality cable.
3. Compression Software
The technical details of codecs are a bit too much for this article. If you would like additional information, you can go to Wikipedia. Here is a quick overview of codecs as it pertains to VoIP. When sending data, VoIP compresses it. This is simply because if the data is too large, transmission can be extremely slow and ineffective. Codec is a software program that can be used for data compression. However, a poor quality codec will lead to poor audio quality.
4. VoIP Location and Hardware
The hardware you choose for you VoIP can affect the audio quality. Most of the most important pieces of hardware is the ATA/Router. The VoIP ATA or Analog Telephone Adaptor, brings ordinary phones to the networked world. The adaptor connects a phone handset to an Ethernet adaptor and therefore connects regular, analog phones with VoIP networks. If you are looking for additional information on ATA, check out Wikipedia.
In general, ATAs should have support for security and firewall, as well as echo cancellation and compression technologies. Many technicians have discovered that certain VoIP equipment can interfere with each and possibly create feedback or buzzing noises and dropped calls. Although VoIP equipment and hardware should be places as close as possible to each other, ATA should not be placed near the broadband internet router. The audio quality can be decreased if they are placed too close together.
5. Computer Maintenance and Hardware
There are a variety of different things that can affect the quality of your VoIP service. Therefore, computer maintenance is extremely important in improving the service’s quality. Make sure that you de-fragment your computer on a regular bases. As well, make sure that you have sufficient memory for the computer and high quality microphone and speakers.
6. VoIP Phone Type/Frequency
The type of phone you have, as well as the frequency can affect the quality of your VoIP. Many people believe that the higher a phone’s frequency is, the better the quality of VoIP. However, in some instances, a lower frequency phone may fit your connection better. You may want to try a phone with a lower frequency if you are experiencing a lot of audio feedback.
Overall, VoIP is a great low cost alternative for communication. VoIP are not passing through, they are here to stay. Major corporations have done some significant research to fix the disadvantages of VoIP service, as well as improve the overall quality. With all of the improvements continually going on with VoIP, it will soon be accepted by everyone as an acceptable alternative to PSTN.

Overcoming The Disadvantages And Improving the Quality Of VoIP
Using Texas VoIP Technology for Your Business Needs
VoIP in Texas is becoming a growing trend in the recent years. Since 2004 the trend has skyrocketed not only among Texas VoIP subscribers but all around the country. Texas has and will remain to be a trend setter for the rest of the country since it is such a large state and very populated. VoIP stands for Voice over Internet protocol. VoIP allows users to have normal phone access through an internet service provider but still use regular phone networks. Which helps users avoid unnecessary long distance charges? For companies the use of VoIP is more practical than regular phones because it allows the companies to cut major costs on their phone bills.Several Texas VoIP users, especially larger companies, can gain a good advantage from the extras VoIP’s have to offer. Since almost every company uses multiple lines and VoIP’s in Texas can have more than one call going over the same connection at the same time it makes it simple for adding those multiple lines. There are several other features that companies can enjoy from VoIP providers such as conference calling, caller ID, call forwarding, and automatic redial. Normal telephone companies charge a decent amount for each of these features where VoIP subscribers pay very little to nothing for them. Also since VoIP’s are already digital it makes for getting a secure line much easier as all they have to do is encrypt the already provided data stream.Several other technology advancements are also coming into the market for Texas VoIP users. Since the VoIP phones are on the same data level as computers it opens up new possibilities for upcoming features such as call routing.As with any technology though VoIP does have a couple of downfalls especially for VoIP in Texas. Since Texas has many hurricane issues the biggest problem with VoIP is that it runs off of modems. Which in turn run off regular power so in the case of Texas VoIP users if a hurricane causes the power to go out they won’t be able to use their phones? Since normal phones don’t rely on traditional electric they are still preferred in some instances over the new technology. The other downfall is not as big but its still causes problems for some users. The fact that VoIP is hardly mobile makes some users skeptical to switch to it. However, with emerging technologies such as Wi-Fi and WiMax it’s predicted that those new technologies will allow VoIP’s to be more mobile, universal, and more widely accepted.Some Texas VoIP subscribers that are larger companies struggle with the problem of highly congested networks. Since VoIP is so easy to add lines to and expand the network it opens up the problem of momentary voice drop out and lower voice quality due to lost or delayed data packets. As technology advances though this problem will continue to diminish.
Although there are still some bugs to work out for VoIP’s in Texas, the convenience and cost effectiveness of the technology out weighs the downside for most Texas VoIP users.

How Can VoIP Support Small Business Growth
Here’s the question …. how can you convince your management that a VoIP solution will support your small business?
The best argument for VOIP is lower communication costs … but it’s not the only reason.
I would suggest using hybrid solutions. Where the bulk of communication, voice, and video are done through VOIP …. and emergency services “fall back” in case of Internet fail is done with minimal classical PSTN solutions.
When I say VOIP from now on I mean 90 % VOIP and some minimal PSTN add-ons.
Why VOIP?
1- Lower communication costs ….
While this is basically clear it still needs to be demonstrated. Assume you have a company that most of its calls are from “overseas” to the USA and vice versa.
You need to get the cost of all such calls currently on one side …. and then compute what would be the cost in case all Intercontinental calls went through a VOIP system.
Now you have the number of calls
Probe the VoIP News and Check the VoIP Reviews
Gone are the regular phone sets! With the busy lifestyle and the need to be always abreast with everything, the consideration of initiating a cheaper but reliable communication access is most possible these days. With the advent of Voice over Internet Protocol or VoIP made communication, both long distance and local calls feasible, cheaper and faster. Interested to know more about the details how VoIP works? Then, make sure to read the latest VoIP news over the net including the available VoIP reviews via the sites that offer objectives reviews in the field of technology.
So with the VoIP news that would make you more interested in setting up VoIP services? If you’re hesitant to set up VoIP service, try considering the new VoIP reviews in the All the Talk site. But first, consider how VoIP works and see if this set up is just for you.
You’ll need to have a reliable broadband connection set up before you could take advantage of the VoIP services. Commonly known as the IP Telephony services, VoIP reviews indicate that this service actually carries signals as digital audio via the speech data compression process. And as early as 1973, VoIP news sprung all over the technology field. From then on to date, there were hundreds of VoIP reviews made making VoIP topic as one of the highly regarded topic in the web. So while essential VoIP news spread all over the world, further VoIP reviews made it clear that there are other facets of VoIP services that need to improve in the course of years. Aside from the functionality of service, the quality of voice transmission and VoIP’s capability to handle emergency calls compared to a regular mobile or landline phones are probed.
In addition to such concerns, VoIP news release in March posted at All the Talk site indicate how VoIP is greatly affected with the previous business recession, the reason being is the heightened cancellation of back to back VoIP services subscriptions. Although VoIP news indicate development and earnings in the VoIP world, All the Talk site reports on one VoIP reviews that there are further developments related to VoIP and its services.
For one, All the Talk reports how the recession affects the VoIP business moving forward. According to the VoIP News published on March 26, 2008, the falling revenue in the VoIP industry made it possible for the recession to take place. This is also true for many businesses holding the use of VoIP services. Yet, there’s a growing concern if the VoIP service is here to stay or not. With the recent VoIP news, it shows that recent developments related to VoIP services include the availability of VoIP to the mobile and landline numbers. In fact, VoIP testing capabilities include having the services set up with an iPhone, a powerful Apple device that’s highly sought after by consumers globally. Lastly, some of the recent news posted on the All the Talk indicates how VoIP evolved from being a mere Internet voice service to an innovative service eyeing for a refined and clarified voice sounding performance.
Voice Over Internet Protocol (voip) in the Australian Marketplace
There is increasing awareness of of late, and understandably so. VoIP has the potential to revolutionise the way we communicate.
Much of the hype has been around residential VoIP, rather than business VoIP communications. It is crucial to understand that major differences exist between residential and business grade VoIP solutions. Relying on a residential grade VoIP service can have disastrous effects for a business, including loss of sound quality in phone calls and down time where your business’ ability to communicate may be cut off entirely. The integration of a business grade VoIP solution has many cost and efficiency benefits for Australian Small to Medium Businesses (SMBs).
The most obvious advantages of a business-grade VoIP solution are the reductions in call and line rental costs, however, there are many other significant business advantages for SMBs of all sizes to realise:

The VoIP Service Provider: Residential VoIP Solutions for the Consumer
As technologies mature and more households gain access to high speed Internet, consumers will come to realize that it is simply more efficient and cost effective to send packets of voice over the Internet than over a point to point circuit switched land line. Long distance charges become a thing of the past, and international calls are pennies a minute if not free to some countries.
VoIP solutions are readily available to anyone with a high speed Internet connection, and the only hardware needed is an Analog Telephone Adapter (ATA) and a phone. For most consumers, utilizing a calling plan from a VoIP service provider is the best solution. Most VoIP service providers will provide the ATA hardware (or software) for free, and monthly charges range from free on up.
Peer to Peer VoIP
The least expensive VoIP solution would be using a computer on a peer to peer network. Offered from such VoIP service providers as Skype or the Gizmo Project, the software is free to download and calls within the network are free worldwide. Calls to PSTN numbers are charged at a low VoIP rate. Peer to Peer VoIP is a software solution, meaning that no ATA is required, and your phone is a pair of earplugs and a microphone plugged into your computer. The downside is that call quality is lacking compared to some of the hardware VoIP solutions available.
The “Pure Play” VoIP Service Provider
Over the past few years, a new generation of upstarts has introduced themselves into the residential VoIP arena. Probably the most successful (at least popularity wise) would be the VoIP service provider Vonage. Thanks to their lavish spending on advertising, the technology of VoIP is becoming mainstream, and the general public is beginning to realize that if the circumstances are right, Voice over IP can be a viable cost saving alternative to the Plain Old Telephone System (POTS).
Vonage, Packet8, and SunRocket are just a few of many companies that are pure-play VoIP service providers. They have no interest in selling you cable TV, conventional telephone service, or cellular minutes. Monthly plans range anywhere from $7.00 to $40.00 and calls are free in the U.S., Canada, and in some cases Europe. International rates vary with many countries as low as 2-3 cents a minute.
These are the companies that have pioneered residential VoIP for the consumer and with their low monthly calling plans, the companies that will keep the giants in the Telecommunications Industry honest.
Telco’s as VoIP Providers
Just as deregulation and the advent of cellular technology in the past, VoIP is poised to revolutionize the Telecommunications Industry. And the large telephone companies, even the cellular phone companies are entering this new era kicking and screaming.
Telco’s like AT&T, the regional Bells and others are happy to provide broadband internet access through DSL, but very few are willing to unbundle the internet service from their conventional telephone services. They could do it technologically, and a few local phone companies are offering DSL on the “local loop”, without the wire with the dial tone. The fact is, having a broadband connection that requires you to also buy a conventional telephone connection pretty much defeats the purpose, thus making VoIP through DSL impractical for most people.
That said, the Telco’s see the writing on the wall and are slowly beginning to implement Voice over IP telephony. AT&T and Quest Communications offer residential VoIP solutions starting at $25.00 and $30.00 respectively, just slightly higher than a pure VoIP service provider. All of the basic features such as call forwarding, speed dialing, and 3-way calling are included, and premium services like virtual phone numbers, conference calling, and call filtering can be had for an additional charge. International rates seem to be somewhat higher than pure play rates, though only by pennies.
VoIP and Cable Companies
If anyone is in a position to win the Telecommunication wars, it’s the cable companies. Massive consolidation in the cable industry has led to huge privately owned networks that in many cases make it unnecessary to route calls over the public Internet. Quality of Service issues can be handled in house, and after all, companies like Cisco Systems pretty much built the Internet and are largely responsible for the development of Voice over IP Telephony.
Cable companies as VoIP service providers have the ability to bundle voice with high speed data and digital cable TV, and are even now running introductory offers of all three for 99.00 a month in some markets. But be careful, introductory offers end and VoIP plans with the cable companies are some of the most expensive to be had.
While VoIP service providers like Comcast and Time Warner generally receive good reviews for sound quality, monthly calling plans cost $40.00 and $45.00 respectively. Not bad when looking at a $70.00 phone bill from Bell South, but over twice as much as a pure-play VoIP service provider. No doubt, a good reliable broadband connection through a cable modem is the ideal VoIP solution (wireless notwithstanding), but you don’t have to use your cable company for VoIP.
In the end, it all depends on whats important to you. If all you need is to call a friend in China on the same network, then a peer to peer VoIP service provider is for you. If you live in an area where it’s offered, a telecom VoIP solution promises lower bills than their conventional connections, provided you can drop the land line.
For those that have cable modems, the choice of VoIP service providers is vast. For the monthly cost of another broadband connection, cable companies will come out to install the equipment and rewire every jack in your house. And they are just a service call away. Alternatively, the pure play VoIP providers offer the lowest rates around, and the quality is usually just as good.
Just remember, it’s all in the pipe. Calls will be as clear as your VoIP service providers’ network is uncongested.
VoIP Internet Phone Services Grow
The new technology surrounding Voice over Internet phone plans (VoIP Phones) and all the different ways they can deployed in home and office environments, makes VoIP confusing to a lot of people. For home users and cell phone customers, it is very simple to use and no knowledge of VoIP technology is needed. Yet, VoIP usage is still not at the level many industry experts thought it should be. The VoIP consumer marketplace is competitive with phone companies and VoIP providers battling for the consumer’s minds and wallets. As long as consumers are content and don’t understand VoIP service and its value, the big phone companies can keep charging excessively high phone call rates and providing fewer services.
Many consumers still lack the information about VoIP phones and Internet phone service plans they need to make a shift to VoIP. Many will wait until there is a critical mass effect. That’s when a large number of people will shift to VoIP and when VoIP lingo is a common part of people’s vocabulary. Since VoIP operates seamlessly with current phone systems, it’s not a technology that jumps out at people.
Not long ago Google was an obscure web search engine that had little consumer usage. But then Google started to make noise, and it did so with the help of students and web marketers who believed it had something to offer. Now, the word Google is used as a verb and people wonder how they ever got along with its info finding magic. VoIP is starting the same way but still hasn’t found a way to move into mainstream consumer lifestyles. Rest assured though, that VoIP companies are targeting a variety of consumer demographic groups such as teens with cell phones, migrating people to Europe and North America who want to stay in close contact with their relatives back home, and businesses with multiple distant office locations who need inter-office phone communications. For regular home phone users, the value proposition they’re receiving is not as compelling. That will change too as VoIP companies research ways to make that home phone service more valuable to consumers, or to make it unnecessary to keep it.
That critical mass event happens when users believe they have a clear cost savings advantage to make the switch from using their regular telephone service to a VoIP phone service. Being able to dump the home phone would certainly provide a reduction in monthly bills, but consumers aren’t dropping their expensive land lines, even though they may have cable television and cell phone bills to boot. In telecommunications, it seems consumers are over-serviced, and a solution is needed. Internet telephony has that potential to eliminate some of the redundant services, but it hasn’t matured to the point where it can shape the phone services market by itself.
Phone companies in defending themselves, put a fair amount of effort into discussing the possible downside of VoIP and some have even put restrictions on VoIP transmissions to try to thwart VoIP service providers. Old stories of lost calls, garbled voice quality, non functional 911 assistance, and loss of privacy don’t carry much weight anymore though. Quality and technical issues are almost all resolved and the services continue to improve. So, if it’s not technical issues that are preventing widespread VoIP adoption, then what is the problem?
Need to Drop the Land Line
Many consumers won’t adopt a VoIP service until they can drop their current phone company land line completely. Despite the desire to do so, many appear to be resisting eliminating their dependence on the old lines. Most don’t want to be paying for two phone services at the same time, yet they do. A billion people on the planet have cell phones now, so that means there are a lot of phone lines that aren’t necessary, or that are too expensive given the value they offer. As long as phone companies can make customer’s land lines indispensable, or encourage them to stay put, they know their customers won’t switch to VoIP plans. So that leaves many consumers with more than one phone, a home phone and a mobile phone, and it’s costing them a lot of money.
For those who don’t make frequent long distance phone calls, the cost savings from VoIP service plans aren’t compelling enough. However, when you add the cost of the call and line features that phone companies add onto the monthly phone bill, the scenario changes. Call features such as caller ID, call blocking, call waiting, and voice mail, are free with VoIP plans. If these aren’t enough to entice consumers, VoIP companies will certainly look to sweeten the offer. Internet protocol communications are improving all the time and there will be more to offer the consumer such as; services via PDA’s, Blackberries, and IP hard phones connected to WiFi and WiMax services.
Internet Phoning Drawbacks
When VoIP users make a call to another VoIP user, the call is essentially free. However, not everyone has a VoIP-based phone to receive VoIP calls. Many only have their land line or in some cases, a cell phone. That means the call has to go from the Internet into the PSTN or public switched phone system in the destination state or country. This is where the cost of a call shows up. Usually the cost is low for terminating the call to the end user. If the caller is making a long distance call however, this nominal cost is a small sacrifice compared to what they’ll be paying on their traditional home phone service.
High speed DSL customers must have their basic phone service, so as long as they need the high speed Internet connection, they might not switch to VoIP. For cable subscribers, a land line is not needed and VoIP works very well with Cable Internet service. For cable subscribers, the land-based home phone really isn’t needed so the jump to VoIP should be an easy one for cable subscribers. If they aren’t making the leap to VoIP, it might indicate a lack of confidence in cable networks. Most people still have trouble comprehending that a voice telephone call can go through the cable company, or that it will be reliable. Cable companies have come a long way with their technology and networks and are more than capable of providing top notch phone services.
With better education of telecommunications consumers and the presentation of a solid value proposition that offers more than a little cost savings, VoIP will grow steadily. For those with international calling needs, VoIP is already the solution they’re looking for. For small businesses with lots of long distance calling, the savings are even more pronounced. What’s needed is more consumer education. With that, many will finally wean themselves from their dependence on that old analog-based land line telephone and launch into an era of cheap digital phone calls. That day is coming soon as the major phone companies are under increasing pressure to raise the price of local phone service in the face of a major shift to VoIP transmission. Critical mass will occur when price plus features create a force that overcomes consumer’s inertia.
