Voice over IP (VoIP) - Everything old is new again VoIPis a revolutionary technology that is completely reworking large and small telephone systems around the world.
What is VoIP(Voice over Internet Protocol)?
VoIPis essentailly the use of computer networks (packet switched), often the Internet rather than the standard telephone networks (circuit switched) to transmit telephone calls.
How it works:
VoIPconverts the voice signal from your telephone into digital signals in the form of data packets at one end, and then sends it over the data network and converts it back again at the other end to voice signals.
This technology has in fact been used for many years by all the large telecommunications carriers to carry their long-distance traffic. Now, thanks to broadband data services (e.g. ADSL), you as the end user can take advantage of this technology.
What are the advantages of VoIP?
The advantages of VoIPare twofold. Firstly VoIPallows you to greatly reduce your telecommunications costs in several key ways. Secondly VoIP gives you advanced features that would be impossible or cost prohibitive to implement using standard telephony systems.
Costs savings: Convergence of data and voice networks - Because voice over IP uses your data network to carry voice traffic you no longer have to manage two networks - one for voice and one for data. Voice essentially becomes just another application on the data network just like email or the web. This greatly reduces both infrastructure and management costs. AMC's (Adds. moves, changes) - With standard PABX systems you need to employ specialised telephone system personnel each time you need to add, move or make a change to a telephone extension. VoIPallows you to simply unplug a handset and plug it back in anywhere on the network without any reconfiguration. The telephone system can also be managed by IT staff just like any other server on the network. Call rates - VoIPfrees you from the incumbent telecommunications carriers who essentially hold a monopoly on the standard telecommunications infrastructure. This gives you access to call rates that are far more aggressively priced. Free interoffice calls - If you have multiple sites throughout Australia or even overseas in another country, you are able to make calls between these locations free of charge using VoIP.
Advanced features: Roaming - VoIPallows you to take your handset anywhere, plug it in and be automatically connected to the corporate telephone system even from home or a hotel room. This enhanced mobility is a great news for teleworkers and businesses who wish to decentralise their operations. Application integration - VoIP"computerises" voice communications. It therefore becomes easy to bridge the gap between data and voice applications. Features such as address book dialing and email/voicemail integration come standard. More advanced applications such as CRM and corporate databases can easily be tied into a VoIPtelephone system and be more cost effectively deployed. Centralised ManagementBecause VoIPessentially turns voice into just another application on the data network, this means that the VoIPserver can essentially be located anywhere and managed remotely. The VoIPserver could even hosted by a third party. This helps greatly reduce the management costs associated with standard telephony systems.
