VoIP : The future is bright
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.
With worldwide revenues from Internet voice technologies expected to grow from about $13 billion in 2002 to nearly $200 billion by 2007, Lets take a look at the different technologies and progress of VoIP.
In VoIP technology already available long-distance phone calls, conferencing, e-mail, and other communications are now affordable and flexible.
Session Initiation Protocol (SIP) retrieves server responses and handles client requests and 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. 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.
Another influential element in the future of VoIP is improvements in 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.
Currently, the most promising areas of development for VoIP are corporate intranets and commercial extranets. 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.
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.
The future of VoIP as a major communication method over the coming years is therefore assured. VoIP Telecommunications are here to stay.
