VoIP has been rapidly embraced by several large businesses in a short time due to diversity of its features and the low cost for local and long-distance calling. In VoIP, all the audio data is transmitted over the internet along with other data. This results in a much lower running cost for both the VoIP provider as well as the consumer. Secondly, because of the internet, it is possible to use VoIP no matter where the caller or receiver is, as long as they are both connected to the internet. The technology has matured to the point were it is no long required of the communicating parties to even possess or use a computer in order to avail VoIP. All the parties using VoIP can be operating over the internet but without a computer.
For mobile users who rely on their laptops for their work, VoIP is especially an advantage because they do not need to worry about a communication loss/delay or about the cost of making too many calls using their cellular phone. VoIP also enables you to forward your voice mail and faxes to your email so that even if you are unable to answer calls at some time they are always there in your inbox. Within a corporate network, it is possible to file, archive, or forward such data to different employees across several offices.
It is possible to get virtual phone number for any area code (that offers VoIP services). That means you could be in one state while using a number out of another. The VoIP telephone numbers can also be configured to simultaneously report a call to the IP Phone, a landline number, and a cell phone before diverting the call to voice mail. A research conducted last year concluded that because of internet telephone and VoIP the number of hours worked each week by an employee increased by 4.
VoIP services are also being integrated with WiFI networks in order to make sure that wireless devices like PDAs can make use of it. This sort of connectivity increases mobility without increasing expenditure.
Another advantage for a large business is that once the IP network for use in VoIP is established, it can be used for video conferencing when not being used for vocal calls.
VoIP are not just economic but they also offer other advantages to most large businesses like email, customer service, voice mail, and video conferencing over the same network. Other applications like accounting programs, filing systems etc. can also be fused into the same network to create a truly global office.
