VOIP Telephony – The Benefits and Limitations

January 25th, 2010



Previously we explored the history and technology that gave
rise to VOIP Telephone service (*see footnotes). Today we will examine
some of the benefits and also the drawbacks of this new opportunity.

In previous articles we discovered that traditional “Landline” type
phone service is set up much like a “Toll Highway”. Billing starts
when the “Circuit” is opened, and continues until it is closed.
Just like travelling down a Tollway, the longer you stay on, and the
farther you travel, the more “Toll Booths” you pass through. These
toll booths are the phone company’s switches, and you get charged
for every one that you pass through.

In contrast, VOIP phones use “Packet” switching. As the broadband
Internet connection is always open, digitized voice signals are
sent to the receiver in discrete packets. The result is that no
“dead air” exists on the line, as no traffic is sent when there is
a lull or pause in the conversation. This allows several two-way
conversations to use the same “bandwidth”, or space that previously
was tied up by ONE call.

This has resulted in great economy for VOIP providers who in turn
pass along the savings to the end user. Most top VOIP plans run
around 30 dollars a month, and the best include International calls
to many countries worldwide within that base fee along with a host
of features like Voice Mail, Caller ID, Call Waiting, Three-way
Calling, Online Access, Etc.

While most major traditional carriers have an “all inclusive” plan,
none that I know of include International calling, and most of their
“basic” plans are double the cost of VOIP. In my experience, the most
coveted features are also charged extra for. Add in the taxes and fees,
and all of a sudden you’re talking REAL money!

The other great benefit of VOIP is the ability to take your device
anywhere and make calls just like you were at home. The best services
are fully find-me, follow-me capable. This means that wherever you
happen to be, your phone number will find you and ring at THAT location.
I use mine with a Laptop, a cheap cigarette lighter a/c converter,
a wireless card, and an old “princess” phone in my truck parked outside
of hotspots all the time. That’s huge. You can have your office in
whatever hotel or airport or Starbucks you happen to be in at the moment.

Having covered most of the benefits of VOIP, let’s examine some of
the drawbacks. The major one is spotty 911 service availability. As
the device is portable, any call to 911 will result in emergency
crews being sent to the device’s address of record, which is set up
when you activate the VOIP device and service. Obviously this doesn’t
do you much good if you are in a hotel in Montana but live in Ohio.

One way around this is to change your address with your provider when
you travel, and then change it back when you return home. Of course,
this only works with domestic addresses, and you must remember to do it.

A better way is to ignore the issue entirely, and keep a very basic,
cheap, no frills service plan with your local phone provider. This will
still be cheaper by far than a full blown plan. Also, you avoid the other
main issue with VOIP- Power Outages. If power goes out, or you lose your
Internet Connection, you lose your phone service. Of course, you run
that risk with today’s cordless phones too, so it’s always a good idea
to have an old hardwired phone around the house, or at least a cell
phone available.

VOIP Disadvantages

January 15th, 2010



Voice over internet protocol (VOIP) is changing the way that the average consumer makes long distance phone calls. The technology is rapidly advancing because companies all over the world are now competing to be your VOIP provider. However, there are still some disadvantages of VOIP – especially when it comes to using the technology for functions beyond the one caller to one caller scenario.

The disadvantages of VOIP can be annoying, but are relatively limited for the consumer. The main complaints regarding VOIP have to do with providing the level of quality of service that customers are accustomed to with regular telephone technology. The reason for this is multifold. VOIP requires a large amount of data to be compressed and transmitted, then uncompressed and delivered, all in a relatively small amount of time. Problems develop in VOIP conversations when this process takes too long and the callers experience one of two problems; echo or over-talk.

Standard phone calls function with a delay of no more than 10 milliseconds. But one major disadvantage of VOIP is that there have been delays of up to 400 milliseconds, meaning that the callers won’t hear each other fast enough to make the conversation flow easily. They will either hear themselves talking or they will start talking again before they have heard the other person respond. Although these problems won’t necessarily happen every time a call is made, it can happen often enough to be annoying.

The disadvantages of VOIP are usually tolerable if the callers are using a free service and the calls are for individual, personal communication. But once a network of users, such as a business, wants to use VOIP, the problems become a little more complicated. Part of the reason is that most networks have a firewall; and most firewalls don’t know how to route a VOIP call once it is received – which phone does it go to?

Plus, multiple users create a problem when judging what amount of bandwidth can be and should be used at any time. If multiple users need to make VOIP calls, it can be difficult for the company to know exactly how much bandwidth to provide – especially if internet access, video conferencing or other data transmission services are using the same path.

Overall, the disadvantages of VOIP aren’t significant enough to dissuade the average consumer from using the technology; especially with the fact that they know that the calls they are making are free. But we can rest assured that the technology will only get more reliable as time goes by.

Make Your Conversations Better With Great VOIP Handsets and VOIP Technology

October 5th, 2009



In this modern age and world, we are gifted with a lot of technological advances that make life not only easier but practically more fun. Common daily tasks can be accomplished in a rush without sacrificing quality because of certain inventions. Ordinary activities become more exciting and fun using certain gadgets. Indeed, the world around has become so much better because of such steps into the future. One example of this kind of technology are VOIP telephones. If you want to know more about this kind of technology, how it can be of use to you, and how it can make ordinary conversations better, then read on.

Voice Over Internet Protocol

The big difference between the common telephone and a VOIP phone is the fact that VOIP uses internet lines to connect one person to another. This means that communication nowadays is no longer limited to those traditional phone lines on poles or underground. Using internet technology, people can now get connected using VOIP handsets that look much like the ordinary telephone – only cooler and better.

How to Use a VOIP Phone

You use such a phone the same way that you use your regular home telephone. If you prefer a wired phone, then it would be great news to say that you can have a long list of choices with wired VOIP handsets. On the other hand, you can also have lots of choices if you opt to use a cordless phone. It would also be important to note that there are now Voice over Internet Protocol phones which work much like the mobile or cellular phone – you can go mobile with it without having to pay the usual high fees.

The Advantages of Using VOIP

There are very many advantages of using this new kind of phone. We will focus on the coolest of benefits.

1. You get to call home and office telephones, mobile phones and even other VOIP phones.

Yes, with this kind of technology, you are not limited when it comes to the type of telephone that you can call. You can still connect to those who use land-based phone lines. You can call anyone with a cellular phone. And of course, you can call other people who use the same kind of technology.

2. You can use your VOIP phone to make local, long distance and international calls.

You can use your new phone to connect to anyone located in any place within the country as well as those abroad. And the best thing is that you do not have to pay for any kind of long distance or international call charges since you are using internet lines.

3. You get to have clear and undisrupted calls every time.

Long gone are the days when you have to settle for conversations that are choppy, unclear and often disconnected. Using VOIP handsets and services, you can now connect to anyone in the world on clear lines. You also do not have to deal with conversations that are cut, disrupted or delayed. All in all, VOIP technology makes all your conversations not only more economical but also a lot better.
