Everything you need to know about VoIP

What does VoIP stand for?
VoIP stands for Voice over Internet Protocol

What is VoIP?
It’s a method for making and receiving telephone calls via the internet, and is also referred to as IP Telephony and Internet Telephony.

What are the benefits of VoIP?
VoIP is becoming increasingly popular for businesses as well as individuals because it is a lot cheaper than traditional telephony solutions – using existing internet infrastructure to handle communications. This can have huge benefits to businesses who make a lot of outbound phone calls.

There are a lot of applications that allow for completely free phone calls over VoIP, but there are charges if you use VoIP as a complete replacement to the PTSN service (Packet-Switched Telephone System).

The increased functionality of VoIP is also a major benefit – with Caller ID, Call Blocking, Forwarding and Mobility all attractive features for businesses.

Another benefit of VoIP is that it allows for voice communication between more than two people. As VoIP compresses data efficiently, it means there is more room on the connection – so conference calls with multiple people in different parts of the world are not only easy to set-up, they’re also very cost-effective.

Are there any disadvantages to VoIP?
As a relatively new technology, there are some drawbacks to VoIP. These are far outweighed by the benefits, but it still pays to be aware of the potential issues. Voice quality can sometimes be an issue during VoIP calls, and VoIP’s dependence on bandwidth can also cause problems.

How does VoIP work?
In simple terms, VoIP works by turning the analog audio signals used in traditional phones into digital data that can be transmitted over the internet.

There are several ways to use VoIP, with the most common three methods being:
• Using an ATA (analog telephone adaptor) – this allows you to connect your traditional phone handset to a computer for use over VoIP
• Using an IP Phone – these look like standard phone sets but are wired differently so that they connect directly with a router
• Computer to computer – this is the easiest and most common way to use VoIP and makes use of standard hardware like a microphone and speakers to handle the VoIP call
