IP and VOIP Telephone Systems

IP phone systems and VOIP telephone systems offer significant advantages over traditional analog (legacy) systems. They cost less and offer a wide range of features simply not available on traditional systems.  IP phone systems are much easier to install and configure than traditional phone systems and they don’t limit your company to a certain number of phones or users. This scalable and flexible infrastructure makes it easier for companies to easily grow (or scale back) and reduces various operational costs.

Our range of VOIP phone systems and IP telephone systems are from globally recognised manufacturers. Our partnerships mean we are ideally placed to supply, install and commission a solution that best suits your business needs.

What is IP Telephony

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user. Much of IP telephony focuses on that challenge.

What is VOIP Telephony

A VoIP phone is a telephone set designed specifically for use in a voice over IP ( VoIP ) system by converting standard telephone audio into a digital format that can be transmitted over the Internet, and by converting incoming digital phone signals from the Internet to standard telephone audio. A VoIP phone allows the user to take advantage of VoIP technology without involving a personal computer, although an Internet connection is required.

What is the difference between IP and VOIP telephony?

VOIP telephony is simply a type of IP telephony.

To see it in a broader picture, think of IP Telephony as the overall concept and VoIP as a means of transmitting voice to implement this concept. An IP Telephony system can, for example, be an IP-PBX, which has VoIP and its standards (SIP, H.323 etc.) along with many other things (e.g. CRM), geared towards better productivity.

Others describe IP Telephony as the overall experience of communicating effectively and reliably using internet protocols; this being achieved by harnessing the power of VoIP by virtue of the latter’s user-friendly features.

Is IP telephony and VOIP telephony suitable for us?

If you're using a traditional business phone system and have expensive call and line charges each month then you should definitely consider an IP phone system of VOIP phone system.

Below we explore the benefits of IP telephony and VoIP and see how it can improve your business voice communication.

Save money

If you don’t use a VoIP phone system for voice communication, then you are a traditional phone line (PSTN – Packet-Switched Telephone Network). On a PSTN line, you pay for each minute you spend communicating on the phone. International calls are much more expensive. Since VoIP phone systems use the Internet as a backbone, the only cost you have when using it is the monthly Internet bill to your ISP. Of course, you need internet access (see our WiFi for business solution), but this causes your monthly cost to be a fixed amount. You can speak as much as you wish on a VoIP phone system and the connection cost will still be the same.

Studies have shown that, compared to using a PSTN line, using an IP phone system or a VoIP phone system can potentially make you save up to 40 % on local calls, and up to 90 % on international calls.

Easy conferencing

On the phone line, only two persons can speak at a time. With IP and VoIP, you can set up a conference with a whole team communicating in real time. VoIP compresses data packets during transmission, and this causes more data to be handled by the carrier. As a result, more calls can be handled on one access line.

Cheap user hardware and software

If you are an Internet user wishing to use an IP phone system or VoIP phone system for voice communication, the only additional hardware you require besides your computer and Internet connection are a sound card, speakers, and a microphone. These are quite cheap. There exist several software packages downloadable from the Internet, which you can install and use for the purpose.

More features

Using VoIP or IP also means benefitting from its abundant features which can make your VoIP experience very rich and sophisticated. You can, for example, make calls anywhere in the world to any destination in the world with your VoIP account. Features also include Caller IDContact Lists, Voicemail, extra-virtual numbers etc.

More than voice

As mentioned, a VoIP phone system is based on the Internet Protocol (IP), which is in fact, along with TCP (Transmission Control Protocol), the basic underlying protocol for the Internet.

By virtue of this, a VoIP phone system also handles media types other than voice: you can transfer images, video and text along with the voice. For instance, you can speak to someone while sending her files or even showing yourself using a web cam.

More efficient use of bandwidth

It is known that about 50 % of a voice conversation is silence. IP phone systems and VoIP phone systems fill the ‘empty’ silence spaces with data so that bandwidth in data communication channels is not wasted. In other words, a user is not given bandwidth when he is not talking, and this bandwidth is used efficiently for other bandwidth consumers. Moreover, compression and the ability to remove redundancy in some speech patterns add up to the efficiency.

Remote working

If you are working from home or remotely, you can still access your IP phone system or VOIP phone system. The portable nature of the VoIP technology is causing it to gain popularity as the trend is towards portable commodities. Portable hardware is becoming more and more common, as are portable services, and VoIP fits in well.

Fax over IP

The problems of fax services using PSTN are high cost for long distances, quality attenuation in the analog signals and incompatibility between communicating machines. Real-time fax transmission on VoIP simply uses a fax interface to convert the data into packets and ensures complete delivery of the data in a very reliable way. With VoIP, there is finally not even the need for a fax machine for sending and receiving fax.

More productive software development

IP phone systems and VoIP phone systems are able to combine different data types and to make routing and signaling more flexible and robust. As a result, network application developers will find it easier to develop and deploy emerging applications for data communication using VoIP. Moreover, the possibility of implementing VoIP software in web browsers and servers gives a more productive and competitive edge to e-commerce and customer service applications.
