Low Cost Telephone Calls
Using A Broadband Internet Connection
Author: Dr Peter EH Smee
Date: Wednesday, 28 June 2006
VoIP (Voice Over Internet Protocol) is a way of using computer equipment to make low cost,
or even free, telephone calls using a broadband internet connection. This article explains the
technology, outlines the options and gives you the information you need to begin to calculate
how much money VoIP might save you. It also explains how to make best use of the many
opportunities and options that are now available associated with VoIP. With some VoIP
telephone services providing unlimited landline calls for as little as £7 per month and calls for
one penny a minute to anywhere in the world, anyone with teenagers in the house, or a
vibrant business to run, is liable to find the information in the following pages a useful boost
to their bank balance. For example, a business using Skype and calling UK National Rate
numbers for 1500 minutes and US numbers for 1000 minutes would pay around £40, whilst
according to the BT website, the BT landline rates for the same calls would be in the region

Each year many families and businesses spend far more than they need to on telephone charges,
especially if they are regularly communicating with friends, family, colleagues or clients, who are
based abroad. This document explains how an internet phone technology, called VoIP (short for Voice
Over Internet Protocol), can save you a lot of money. It will also demonstrate that behind the jargon,
users of VoIP can get started quickly and easily, even if they are only familiar with a few aspects of
computing. In practical terms, if you can word process, you can use VoIP. In fact, even if you can’t
word process, you will probably find VoIP easy-to-use, as long as you know someone confident
enough to install a couple of pieces of software on your computer. In short, use of VoIP is easier than
typing, easier than programming a microwave, and definitely easier than getting a video to record
your favourite television programmes. And the benefits of VoIP are that if you regularly spend more
than £7 a month on calls to UK landlines, or if you regularly call numbers in another country, VoIP
can save you money. For example, a business using Skype and calling UK National Rate numbers for
1500 minutes and US numbers for 1000 minutes would pay around £40, whilst according to the BT
website the BT landline rates for the same calls would be in the region of £250.
VoIP equals low cost calls to anywhere else in the world. In addition,
VoIP enables businesses to set up low-cost virtual telephone lines in almost any major city in the world
VoIP equals free audio or video calls to people on the same network

What you need
VoIP makes most sense to people who already possess both a computer and a broadband service, and
who do so because they want to surf the internet. If you have the equipment needed to surf the web,
then you have all the kit that you will need to get started with VoIP. However, if you do not yet
possess a computer and / or a broadband connection, and if VoIP would make the difference between
you buying or not buying a computer, then the following is some food for thought.
If you need to buy a new machine... If you only want a computer to undertake simple office tasks,
surf the internet and communicate, then you can purchase a desktop PC running the LINUX operating
system from DABS Computers for around £150. This comes with a lot of free software and there is
much more software that you can download, if you need it (see our other articles). Add in the cost of a
large 17” LCD monitor for under £150 and you have a well specified computer for under £300.
Alternatively, for about £100 more, you can get a similarly specified computer with Microsoft
Windows installed (again, see our other articles for advice on free and low cost software that you
If you need to buy an internet connection…At the time of writing, a fast broadband connection in
the UK is available for between £10 and £20 per month. Such a connection would be enough to run
one and perhaps two separate VoIP phone lines, as well as leaving capacity for some limited internet
surfing at the same time. As a case study example, when talking to friends in business, it becomes
clear that by using VoIP many local businesses could massively cut call charges to customers and
suppliers, especially if those businesses are making a lot of calls to Europe or transatlantic calls to the
USA. VoIP can be up to ten times cheaper than standard trans-national call rates.
In short, VoIP offers lots of savings, but does require a little planning to be useful.
Hence the reason for this article.
For someone on the move, a £400 WiFi enabled laptop from Acer, plus a £30 Logitech camera with
microphone, plus the free Skype software gives you a mobile telephone that is much cheaper than your mobile
phone. In addition, you can use it to video conference.

The first hurdle related to VoIP, and the hurdle that probably causes most people to delay adopting a
VoIP-based telephone service, is the connection. A landline telephone connects to a simple socket
and is always ‘connected’ until you unplug it. We are familiar with this concept and it therefore
appears simple to us. In comparison, the connection options for a VoIP-based service can appear a
little bewildering. The following are the most common options from which you can choose.
Assuming that you have a computer and a broadband service, the cheapest VoIP ‘set-up’ can be
obtained by purchasing a £5 microphone and plugging it into the ‘microphone in’ port on your
computer. All you need to do then is to register with a free service, such as Skype, and download and
install the appropriate software (which in many cases is also free). You are then eligible for free or
low cost calls to other users on your network and inexpensive calls to everyone else.
If you want to be more sophisticated, for a little more investment in time and money, you can use
slightly more expensive wired headsets, or you can use one of the many significantly more expensive
wireless or bluetooth headsets. Whichever option you decide to adopt, the pros and cons are relatively
similar. If your computer is switched on, you can gain free and easy access to VoIP services, such as
Skype (more about which later). However, the downside with this plan is that if your computer or
your internet connection is switched off, your telephone service is effectively disconnected.
Thus, if you want to make use of a computer as your VoIP ‘gateway’, it is best to think of VoIP as
supplemental to your main landline, rather than your main service, unless your computer and your
internet service can be relied upon to be ‘always on’.
For advice on headsets,
there are many articles at http://www.fineheadsets.com
If you use a computer as your VoIP gateway, then if you are communicating with other computer users you can
engage in free video conferencing. VoIP provides opportunities for businesses to set up video networks
between themselves and their suppliers and clients. Remember that both audio and video calls between VoIP
users on the same network are (normally) free.

In terms of increasing sophistication, the next kind of VoIP technology that may be of interest
concerns anyone with a PocketPC, such as an IPAQ or Palm, and anyone with a Play Station Portable
(PSP). Many VoIP services provide software that enable PocketPCs to act as a telephone. Some are
about to release software that will enable a PSP to act as a VoIP phone. Hence, if you have (or can
obtain cheaply) a WiFi enabled PocketPC or PSP, you will be able to use it as a telephone whenever
you are in the vicinity of a WiFi network, either at home or in the office or when you are on the move.
Given that many WiFi enabled PocketPCs are also Bluetooth enabled, this means you can use your
mobile phone’s Bluetooth headset with the PocketPC as an alternative to making expensive calls on
your mobile phone when out and about in a built up area. At the time of writing, many towns and
cities are in the process of rolling out area-wide WiFi coverage. Thus, over the course of the next
decade, many cities will have WiFi as a very real alternative to the mobile phone network.
In addition, if your PocketPC has the option to add a camera, you will be able to turn it into a
videophone. Plus, if it has a memory card slot, by adding a couple of gigabytes to memory you will
make your PocketPC into an effective phone/file storage device/media player.
Give your PocketPC a new lease of life as a video phone, file storage device and media player.
Always bear in mind that games machines like the PSP are also mobile computers.
(See skypetips.internetvisitation.org, geekzone.co.nz and Skype.com)

Many towns and cities are planning extensive WiFi coverage.
Free WiFi is available in Portland, USA, Rome Italy and Penzance in the UK.
Even now, many areas in which people meet have WiFi coverage.
While coverage currently comes at a cost, expect this expense to diminish as city wide WiFi becomes a reality.
In South Korea, who lead the way in broadband coverage, 100 meg connections are not uncommon,
and increasingly provision of free WiFi is seen as a way to entice additional business.

Two other ways to connect to VoIP services which do not rely on the use of computers, are as follows.
Both are attractive options because neither relies on your computer being ‘on’, hence, both options
more closely mimic a normal landline telephone (though, of course, they do rely on an ‘always on’
broadband internet connection). The first option is to connect a normal landline phone to network
adaptor, which plugs directly into one of the network ports on your internet router (assuming that you
have one). The second option is to purchase a WiFi enabled phone that can connect direct to your
WiFi enabled router (again assuming that you have one).
But first, a few words for readers who have not previously come across the concept of a ‘router’.
If you have a broadband internet service you will have a modem provided by your service provider.
This may be an ADSL jack, which connects (ironically) into a telephone socket and which keeps your
computer broadband electronically separate from your landline telephone conversations. Alternately,
if you have a cable connection via the optic cable that brings your cable TV into your house, you will
connect your computer equipment into a cable modem which keeps your television, landline and
computer connections separate within a single optic fibre cable.
Experienced computer users normally place a device called a router between their machine and the
ADSL jack or cable modem, provided by their ISP. The router provides at least two facilities that a
cable modem does not. First, a router usually contains a hardware firewall that prevents the external
world from ‘seeing’ if you have a computer and prevents hackers from sensing whether that computer
is switched on. Second, a router contains a line of network sockets into which additional computers or
network adaptors for VoIP phones can be plugged. This enables several computers, VoIP phones and
other network devices to use the same internet connection. Third, if your router is WiFi enabled, it
enables other WiFi devices to connect to the internet. For example, laptop computers, IPAQ
PocketPCs, PSP games consoles, WiFi web cams and WiFi VoIP phones.

Bought from maplin.co.uk, this model was less expensive to buy
than the next expensive rival. It also came with two WiFi cards, which its rivals did not.
Plus it only took a few minutes to get a secure, password protected WiFi network up and running.

To connect a landline phone into an existing routr, you need a phone to network adaptor. Of the
many adaptors available, one that has good reviews on the web is the Linksys Phone Adaptor 2-Ports
for VOIP @ £45. As the name suggests you can connect two phones into this adaptor, which means
you can use it to give access to two separate VoIP services. Any landline phone can be used with the
adaptor but as an illustration you might consider the Panasonic KXTCD 430 DECT Digital Cordless
Phone (@ £15), which can be bought for a bargain price in a number of outlets.
In short, you can have a single fully functional, cordless VoIP system for around £60. Or you can set
up two VoIP telephone lines for a total investment of £75. Alternatively, if you want to go beyond
voice and enter into the world of video phones, products such as the Visufone are entering the market.
Such video phones connect directly into a network socket and provide video as well as audio chat but
without the need for a computer. However, the additional video functionality does not come without a
cost. At the time of writing, the Visufone has a price point around $400 in the US, with a UK price yet
to be determined.
Left: cordless phones can connect to VoIP network adaptors.
Right: the Vuzufone brings both voice and video conferencing
without the need for a PC, but does so at a price.
Moving focus away from wired network connections to WiFi network connections, again, at the time
of writing there already exist a number of VoIP WiFi enabled phones, with more about to be released
onto the market over the next few months. Netgear is about to launch a WiFi phone that is Skype
compatible in the summer of 2006 (for £140), whilst Accton are racing Netgear to the market with the
VM1185T WiFy SkyFone, at a slightly lower price point. At the same time, at the high end of the
market Philips is preparing to launch its VP5500 in the autumn of 2006. This is a phone system which
includes a camera and links to a television for video conferencing, without the need for a computer
(price has yet to be announced).

Meanwhile, over the horizon, come a number of additional technologies which will be worth keeping
an eye on. For example, there are products and services for enabling a small business to run a VoIP
based switchboard. As an instance of this technology, a quick search in google will enable you to
locate people who can advise how to set up a complete virtual company, complete with virtual
external numbers around the world and a virtual internal telephone system which runs across your
computer network. As another example, Scandinavian company IPDrum have created a cable that
you can connect to an old mobile phone (assuming that like many people you have an old, surplus
mobile in your home). You use the IPdrum cable to connect your old mobile to your computer which
is running Skype. Then, if you were to want to call abroad, instead of having to pay expensive mobile
connection charges to other networks you phone your old mobile at home and your computer forwards
your calls at the cost of your national rate mobile-to-mobile charge, plus the much less expensive
Skype rates (of about a penny a minute). Finally, expect the next generation of mobile phones which
have VoIP and / or WiFi capabilities built into them, so that when you are near a WiFi hotspot
your phone will call out on VoIP, meaning that you only incur high mobile phone charges when you
are out of range of a WiFi transmitter.
The Nokia E series VoIP/WiFi/mobile phones,
though Skype has yet to be ported onto the Nokia Symbian operating system, and
internet postings were unclear just how much software was yet available to make full use of these phones.
In summary: to recap the story so far, the absolute least cost VoIP solution is to attach a microphone
of some kind to an existing computer (cost = £10). The next least expensive option is to get a
telephone-to-computer-network adaptor and plug the adaptor into your router, assuming your router
has a spare network socket, then attach a cordless landline phone into the adaptor and you have a
VoIP solution that will work even when your computer is switched off (cost = £60). Other options
worth considering, but which are only low cost if you already possess the equipment, are: (i) making
a WiFi enabled PocketPC into a Skype VoIP phone, (ii) making a PSP (Play Station Portable) into a
wifi enabled VoIP phone, or (iii) renovating an old computer for use as a VoIP/video conference
phone. Finally, (iv) remember that a new desktop PC with the Linux operating system can be bought
for as little as £150 and would be compatible with many VoIP providers, giving you a phone and an
additional computer filled with free office software for very little expenditure (cost = £150).

In this section the focus will fall upon one of the main ‘players’ in the VoIP market, Skype. As a
comparison, the costs and benefits of Skype will be compared and contrasted with those of another
large VoIP provider, called Vonnage. The overall conclusion is that, like the options that face a new
entrant to the mobile phone market, the best VoIP provider will depend upon the kind of telephone
calls that you make. Each service is optimised for a different client group.
Skype (skype.com). Skype has the great advantage that it costs nothing to subscribe to their basic
service. Using this service, calls to other Skype numbers are free (wherever they are in the world).
Thus, if you can persuade those with whom you converse on a regular basis to also subscribe to Skype
you can enjoy free VoIP audio and video calls, which for well organised families, groups and
businesses can obviously save a lot of money. Where Skype make their money is by selling two
commercial services to their huge user-base. These services are Skype-In and Skype-Out. Skype-In
enables a business to set up a telephone number, along with voice mail, in pretty much any city in the
industrialised world, for a cost of €30 (Euros). In contrast, Skype-Out sells you call credit that enables
you to call any landline in the world for a cost of 1.1 pence per minute, with calls to mobiles being
charged at 21p a minute. As an additional inducement that will be of interest to marketeers and
educators, Skype are testing a service in which you can web cast to100 people simultaneously in a
kind of electronic lecture theatre.
Vonnage (vonage.co.uk). Vonnage has a very different commercial model to Skype. With Vonnage,
you pay a small ACTIVATION price to begin an account, containing a single UK Vonnage phone
number. (However, this price does include provision of a LinkSys phone-to-computer-network
adaptor, specifically customised to work on the Vonnage network, and so is an inexpensive way to
obtain such an adaptor). Then, with regard COST OF OUTGOING CALLS, you pay a flat rate fee
which covers all calls to UK landline phones. The flat fee is £8 for residential customers, £20 for the
first phone in a small business and £10 for each subsequent phone in a small business. At first glance,
the £20 cost for a first line for business might appear high, but there are some additional services that
come ‘free’ with the plan. For instance, a free fax line.
When comparing the two VoIP services, an initial inspection makes Vonnage look very attractive. The
strength of the Vonnage price plan is that you know what you will have to pay. However, on closer
inspection you discover that there are a number of hidden extras that can quickly bump up the price
that you will need to pay. If you call mobiles then you are charged an extra: 20p for daytime, 15p for
evening and 5p for the weekend. You are also charged 2p a minute on calls to many foreign countries.
Thus, Skype is better for a business making less than 1500 minutes of landline calls a month because
the monthly costs associated with Skype-Out would be lower than the £20 charged per month by
Vonnage. Over 1500 minutes of landline calls and the choice between the two services depends on the
number of international and mobile phone calls that need to be made, and when. Assuming business
hours, the mobile phone charges are equal and can therefore be ignored from this comparison. On
calls to America, the difference in the rate is between 0.5 and 1 penny per minute (the Vonnage table
of rates did not specify whether VAT was being charged). In the grand scheme of things, even 1000
minutes of calls would only make £10 worth of difference to the final bill and so may not be worth the
time it would take to worry about the price differentials between the two plans. Both VoIP services are
very much cheaper than BT landlines, which for 1500 minutes of national calls and 1000 minutes of
international calls would (according to the BT web site) cost 10p a minute for daytime calls to both
(non-local) UK and US landlines, giving a total spend of £250, compared to the total VoIP cost of
between £35 and £45.
In short, if you have a huge volume of calls, the decision will probably depend upon whether you
value a free fax line, or more importantly, which network (if any) contains the people you are calling,
because typically calls between people on the same network are free, no matter where they are in the
world. If you can get the people you wish to call to subscribe to Skype, then your call charges drop to

VoIP presents some interesting opportunities for large or extended families and groups of friends,
particularly if they are widely distributed throughout the world. And the future of VoIP looks assured
in urban centres in which widespread WiFi is planned, implemented and maintained. However, it is
businesses that stand to gain most from embracing the opportunities that VoIP offers. For example,
imagine a small business with two or three staff selling small products across the internet to a world
A good solution for a small business, with both a national and an international focus, is to use Skype
allied with a LinkSys telephone-to-network adaptor and two cordless phones, each with a separate
Skype account associated with it, one account for outgoing calls and one account for incoming
On the Skype account designated for incoming calls, the business should purchase Skype-In, with a
virtual telephone number in all the countries containing an existing or a potential customer base.
Skype-In costs around £20 per year per number and, arguably, this is a small price to pay for a
telephone number that immediately communicates to international customers. There is also a
commitment to both sales and after sales service. A national rate number implies a much more
significant ‘presence’ in a country than does a web link.
On the Skype account designated for outgoing calls, the business should purchase a single Skype In
number, along with some Skype-Out credit. This phone can then be designated for national and
international calls. It is also the number that can be given to suppliers and to others that you do not
wish to phone the main, advertised office line. The business can then keep any advertised landlines for
the use of incoming customer orders and customer service, associated with UK customers. The benefit
of this strategy being that the number of costly landlines can then be minimised.
In addition, create two additional Skype accounts, which do not have either Skype-In or Skype-Out
associated with them, and install these on one or more computers. Use one of the accounts as a
private circuit between the business, staff who are off-site in a WiFi enabled location and support
services (assuming that support services would also like to save money by adopting Skype). Use the
second additional account as a video link, advertised on your web site, for clients who would like to
video link to you for free, rather than pay any phone charges at all. (Though you may want to limit the
times that the link is operational, and thus buy a Skype voice mail which both takes messages and
tells callers when the link will next be operational).
In terms of costs, the preceding solution would involve a capital outlay of £75-£100 and a yearly
outlay of around £100-£120 (assuming 5 Skype-In numbers spread around the world). In terms of
benefits, call charges would drop to about 10-15% of their current level. There would be dedicated
lines enabling suppliers and others to call in without disrupting customer sales or customer care lines.
International customers would feel more confident because a local phone number would allay fears of
having to make international calls to place orders or resolve customer care issues. Finally, if repeat
customers and other important ‘contacts’ can be persuaded to also migrate to Skype then a proportion
of all call charges, for everyone, will fall to zero, wherever contacts associated with the business are
located within the world.
As a final thought, it would be wise for small businesses to keep abreast of developments with Skype
web casting services with a view to making regular web casts about products and services, which
potential clients can view and to which they can respond. This would be a relatively novel service in
many sectors of business and thus could be used to both directly communicate with clients and
potential clients, but also as a piece of news placed in relevant journals and periodicals, to raise the
profile of the business in general.
