VoIP - Future Developments For Users

VoIP is a telephony term for a set of facilities for managing the delivery of voice information using Internet Protocol (IP) and is the future of communication.

Here we will look at changes that are coming that will increase what is already substantial growth in the industry.

With Voice over IP -- businesses have the ability to manage calls at the IP layer which enables operational and productivity benefits that have never been available before at such affordable price.

Worldwide revenues from Internet voice technologies are expected to grow from about $13 billion in 2002 to nearly $200 billion by 2007.

The Future Of VoIP Projected Growth

When it comes to VoIP technology already available long-distance phone calls, conferencing, e-mail, and other communications are now affordable and flexible.

VoIP technology however is developing and some of the developments that will ensure the future of VoIP are outlined below

The Future Of VoIP SIP

Session Initiation Protocol (SIP) retrieves server responses and handles client requests.

This technology is able to determine the end system that will be used for a communication session, automatically sets the relevant parameters of the communication at receiver and user ends and then manages call transfer and call termination.

In addition, SIP allows users to initiate and receive communication from any location and networks are also able to identify users, wherever they are.

This technology is an alternative to H.323, which is the protocol, used for IP videoconference transmissions for VoIP up to now.

SIP has taken VoIP technology forward in terms of operational efficiency and many VoIP vendors are now including SIP as standard, bringing SIP to a growing audience.

VoIP The Future - VoIP Gateways

Another influential element in the future of Internet-telephony is improvements VoIP gateways.

Gateways are developing from PC-based platforms to more robust embedded systems, which will be able to handle an increased amount of call traffic.

The economies of scale of placing all traffic- data, voice, and video-over an IP-based network is highly attractive to corporate users.

The reason for this is:

IP will act as a unifying agent, regardless of the actual underlying architecture (i.e., leased lines, frame relay, or ATM) of a companies network.

VoIP The Future - Corporate Intranets & Commercial Extranets

Currently, the most promising areas of development for VoIP are corporate intranets and commercial extranets.

Their IP-based infrastructures enable operators to control who can use a network.

Commercial extranets, based on conservatively engineered IP networks, will deliver VoIP and facsimile over Internet protocol (FAXoIP) services to the general public, by guaranteeing specific parameters, such as packet delay, packet jitter, and service interop.

Companies are already looking to remove fax traffic off the PSTN and relocate it on to the Internet and corporate Intranet, through FAXoIP gateways and via IP-capable fax machines.

Video conferencing

Another area of growth will be video conferencing.

Video conferencing (H.323) with data collaboration (T.120) will become a popular method for corporate communications in the future, as network performance and interoperability increase.

VoIP The Future Expanding Services & Lower Cost

More user-friendly devices and increased promotions are starting to be seen by wider audience and this education, combined with ease of use of VoIP technology is needed for any new technology to gain trust and grow.

For instance, new VoIP telephones are being offered at cheaper prices in a variety of colours, with touch screens that are getting easier to use.

Prices in all VoIP services will continue to drop, as the market grows and competitivness increases.

The future of VoIP as a major communication method over the coming years is therefore assured. VoIP Telecommunications are here to stay.

VoIP - A Basic Introduction

Voice over IP (VoIP) technology, or IP telephony, is simply a system for transmitting telephone calls over data networks, such as the ones that make up the Internet. The efficiency, flexibility and cost savings of VoIP will be taken advantage of by a growing number of personal and corporate users.

In this report we will look at the history, growth, flexibility and advantages of VoIP based systems over traditional public switched networks, (PSDN). Let's look at why VoIP will change the way we communicate forever.

The Disadvantages Of Traditional PSDN Networks
  • With PSDN calls are made using circuit switching techniques.

  • PSDN simply means that an individual call uses a dedicated path for the total duration of the call.

  • During a telephone conversation of this nature only about 50% of the bandwidth is used at any given time.

The reason for this is a call consists normally of two people, one person listens and one person talks, which reduces the bandwidth. This is further reduced as there are natural pauses in conversation such as pauses between words, people thinking, pauses for breath etc. The connection is of course reliable for voice transmission, but its drawback is that, it is very inefficient in its use of bandwidth.

This has kept telephone costs relatively high until now, but VoIP provides the solution: A more efficient use of bandwidth.

The Advantages Of VoIP

Voice over IP, (VoIP), is a way of converting the analogue signals when using a phone, to a digital format (across a network) and then back into analogue when it reaches the receiver.

In a VoIP network, digitized voice data is highly compressed and carried in packets over the IP network. Using the same bandwidth, a VoIP network can carry many times the number of voice calls as a switched circuit PSDN network.

The net result of this obvious.

VoIP can result in huge savings on the amount of physical resources required to communicate by voice over long distances. It does so by providing a far more efficient use of bandwidth, one of the fundamental drawbacks of traditional telephone networks.

There is of course, much more to VoIP than just sending the packets over the Internet.

There is an agreed protocol for how computers find each other and how information is exchanged in order to allow packets to flow between users, there is also an agreed format, (called payload format), which covers the content of media packets.

VoIP A Total Global Telephony Solution

VoIP allows us to use a single high-speed Internet connection not just for voice but, video, and data communications. This is known as convergence and is one of the primary drivers for corporate interest in the technology.

The benefits of convergence are obvious:

By using a single data network for all communications, it is possible to reduce overall costs of communication for users.

A VoIP service provider can be located anywhere in the world; a person with Internet access is not geographically restricted in their selection of VoiP service providers. Lower costs for you and everyone. This competition enables low communication costs for anyone no matter where they are in the world.
