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.
