This term
VOIP has been bandied around for a while now and for those who are not tech
savvy it can be pretty confusing. Even those of us who are technically inclined can be bamboozled from time to time. In this post I will attempt to cut through the tech and try to explain what it is and how it can save you a lot of money.
What has this to do with the iPhone? Up until recently Apple has placed severe restrictions on the use of
VOIP applications on the iPhone but they have now dropped them and it now makes it far more attractive to use
VOIP and thus potentially save you a bunch of money.
VOIP who?VOIP is an acronym meaning Voice Over
IP, or Voice Over the Internet. Many people have heard of
Skype and the
associated product
Skype Out. This has been around for many years and has become quite popular and although it does use a voice over the
Internet type
system it is not exactly the same. With
VOIP you can use a regular phone you buy from K Mart, plug it in to a dedicated box (
ATA) and use it much like a normal home phone.
Skype uses its own system of sending the voice information but
VOIP uses a standard system called SIP that is supported by most network equipment manufacturers.
Many companies now use VOIP on their phones and if you work for a large company chances are you use one at work. Corporations and organisations such as
Telstra, IBM, HP, and the
CSIRO now either completely use
VOIP or are starting to introduce
VOIP for their telephone service.
How Does It Work?Lets look at your average company. Put It In Here Inc (
PIIHI) has offices in Adelaide Melbourne New York and London. They use your regular
PABX (local office exchange) in each location. The
PABX has a yearly
maintenance contract and has quite a high cost to the company. Every time the company makes an interoffice call it incurs the regular STD,
ISDN charges and outside calls incur normal phone charges.
PIIHI also has computer networks in each office and
Cisco provide the network equipment and maintain their network.
PIIHI decide to go with a
VOIP service. They have to upgrade all of their network equipment to cater for the
VOIP service (but it was due for an upgrade anyway). They also have to buy new phones at a cost of about $800 each but this is a fraction of their total
Comms budget. But now everyone in the
office has a smart desk phone with headset and a computer based phone management system to manage favourites, voice mail and
re directions. All of the employees can now redirect their desk phone to any other phone in the company or even to their laptop so that they have full access to their phone service on a headset on their computer. If the employee wants to change desks they simply plug their phone and computer into the network point at the new desk. In fact regular telecommuters can simply plonk themselves down at any desk and have computer and phone available. That is not the best part. Because all offices are on the
Internet inter-office calls are now free and outside calls cost a fraction of what they used to cost. All calls to Adelaide, Melbourne, London and New York (where most of
PIIHI's customers are) are now free from all
PIIH offices. Thus the total
Comms bill for
PIIHI is now close to zero.
The
VOIP service that you an I would use for our personal use does not have all of the fancy features that the
PIIH inc service has but it is much more like your home phone but cheaper and more versatile.
OK, I'm Confused. Get to the point...Fair enough. This has nothing to do with your humble iPhone, or does it. Bear with me.
So
VOIP calls are made via the
Internet and cost next to nothing, especially if the person at the other end is on the same system as you. How do I set it up?
There are a number of providers who can provide your average punter such as you or me with their own
VOIP service, two of which are
Pennytel and
MyNetFone. There are a number of ways of using this service but I will stick to the three that we are likely to use.
Firstly you can use what is termed and
ATA device. Both
Pennytel and
MyNetFone can supply and
ATA device
preconfigured. At its simplest the
ATA device has a power socket, a network socket and a phone socket. All you need to do is plug it into your home network, plug in an ordinary phone and it just works. You can start making calls immediately. The
ATA device costs from about $20 to $100. Pretty
simple. Once it is plugged in your new phone works exactly as if it was your regular home phone.
You can also use
VOIP it on the computer using some software and a headset. It is similar to
Skype here. Again you just make your phone call as if you were using your home phone.
Finally you can get iPhone apps that work exactly as if you were using your iPhone to make a phone call, except you are not using your phone's
sim to make a
cellular call, you are using your data connection (3G or
WiFi) to send the
VOIP information.
How Much is The Going to Cost Then?If you want to only use it at home using your
ATA device then it will cost you the
ATA device, phone if you do not have a spare and the cost of the calls. Different providers have differing charging structures but they are typically
around 10c per call
untimed inside Australia and 10c per minute to
major international centres.
If you use it on your computer there is no extra charge. The computer
software is typically free (but there
may be a one off license fee for some parts of the software).
There and a
number of iPhone apps varying from free to over $10 and
Pennytel does have a free dedicated app but it only works if you are using
WiFi.
Pennytel are planning an update that will allow it to be used over the cellular network but that is not yet released.
My two favourite providers
Pennytel and
MyNetFone have differing price structures but the most basic plan is free and costs inside Australia to fixed lines are 8c and 10c
untimed. If you want people to be able to ring you on your
VOIP service then you need a DID (Direct In Dial) number. This usually costs about $5 per month but this depends on the plans and specials that they may offer from time to time. This is not necessary for
Pennytel to
Pennytel, or
MyNetFone to
MyNetFone calls. As a for instance, one of my friends save roughly $2o odd on his
wife's first call to the UK. Instead of paying over $20 the call cost about $2.50 using
VOIP.
Go to the links above for more details on the plans but most people can start with the
untimed plan and see how they go. After all the basic plans do not have any monthly fees.
My ISP Does VOIP. And what about Naked.Most
ISPs now provide a
VOIP service but you should compare the price of your
ISP with other
VOIP providers. They usually incur a monthly fee, they are more expensive and do not have flexible plans. Also having multiple providers which do not incur a monthly fee is handy. It enables you to use the provider that provides the cheapest rate for each type of number. It is also handy to have a backup provider in case one of them is having technical difficulties which does happen from time to time.
A number of
ISPs are offering a
naked broadband service, some with included
VOIP. This means that you can cancel your home phone and just use the
VOIP service as your primary phone with your mobile as a backup. This can save money but do your sums first. What can appear to be a good deal may not turn out quite as good once you add it all up. But going
naked is certainly an
option, particularly if you can use
voip on the iPhone using one service and you have an
ATA device with a DID number from another service on your home network. In a last resort people can still contact you via your mobile phone.
What about the iPhone Apps?You have done your
sums, chosen a provider(s) and you are ready to get it onto the iPhone. What options do I have and how do I do it?
One thing I need to highlight is that you can only use one
voip service from one location at a time. This is important to understand. For instance, if you have your
ATA device at home and you connect to your
VOIP service from your iPhone then the
ATA device drops its
VOIP connection. In fact I believe (but am not sure) that you cannot connect to the same
VOIP provider with two differing user IDs over the same
broadband connection. In other words, if two people in the same house have two different
VOIP accounts with
Pennytel they cannot both use it through the same
ADSL connection. However you can use the cellular network if this happens.
The following are some of the many
VOIP apps that are available and their strengths and weaknesses. These are not
recomendations just a very brief
overview and you really need to do further research before spending money on any of the paid apps, especially the more expensive ones.
PennytelThis can only be used with the
Pennytel service. It works fine and all that is required is that you put in your
UID and password. You will find this in the
confirmation email they sent you. Connect to
WiFi, open the app, type in the number or choose from your contacts and dial to your hearts content.
Pennytel are working on an update for
VOIP over 3G.
Pros: Free. Easy to configure. Dedicated to
Pennytel. Can receive calls. Very secure.
Cons: Does not work without
WiFi, does not have push, does not support other providers.
FringThis is more of a social networking app with
IM integration including
VOIP. The
VOIP part is fairly basic but it is pretty easy to configure. However it requires a
Fring account to use and some may see this as a security issue.
Pros: Free, easy to configure, works over
WiFi.
Cons: Only supports one account. Not
configurable for improved quality. Requires a
Fring account which posses a possible security risk.
iSipSimpleThis is the free version of
iSip which is probably the most feature rich
VOIP app. See
iSip below.
Pros: Cheap $1.19.
Configurable for a wide range of options.
Preconfigurd for many popular
VOIP providers for easy setup.
Cons: See the full version for additional features.
iSipThis is the full version of
iSipSimple and is one of the more expensive clients but has everything one could possible want. It supports multiple accounts, inbound calls, push
notifications of inbound calls, contacts integration,
recents, favourites, and can be used over the cellular network.
The push service does not work for some providers and although many people claim that push works fine I am one of the many who have not been able to get push working. I have the latest version and I can receive and answer calls using push but we cannot hear each other when the phone answers. I have also found the inbound calls are somewhat unreliable.
Pros: Works over 3G. Supports Push. Simple
configuration for many
VOIP providers. Multiple
acounts.
Cons: Push does not always work. I have found it somewhat buggy. Expensive $7.99.
V PhoneThis is almost as versatile and has many of the features as
iSip but without push. I have the 4.0 Beta OS installed and cannot get V Phone
woking so I cannot comment on its features but for the price it seems quite good unless you want push
notifications.
Pros: Works over 3G. Two accounts. Contacts integration. Simple setup with many
pre-configured providers.
Cons: Does not
support push.
NimbuzzThis is a generic social networking app that also allows voip calls. By default it uses the Nimbuzz voip service but you can configure it to ues your own voip account.
Its features are somewhat limited and has no call history or favourites but for a free simple client that includes integration with other social networking sites is perfectly fine.
Pros Simple, can include other social networking services in the same client, free.
Cons, no push, no favourites or recents.
AcrobitsThis is a fully functional client that supports multiple connections, push, favourites, avatars and an in app purchase of G.729 codec. The G.729 codec is licensed so requires an additional purchase for most clients that support it.
It is said to be extremely easy to set up but I cannot confirm this since I have not used it. However from the list of features I cannot see anything missing. However at AU$9.99 it is at the more expensive end of voip clients.
Pros: Push, multiple accounts, favourites and recents, many features, in app purchase of G.729
Cons: The Expsnsive that I have reviewed.
ConclusionI hope this gives you a better
understanding of
VOIP ans provides you with the confidence to get your
voip account and start saving money on phone calls. For
a small number of people
VOIP will not really save much money but for most of us we can save a large proportion of our monthly bill with
voip.
Go to one of the voip providers, sign up for a free and PAYG account, get one of the free clients from above, set it up and try it out.
