The term, Voice over Internet Protocol (VoIP), refers to a collection of transmission technologies, which make voice communications possible over the Internet. It is also known as Internet telephony and helps the conversion of voice into a digital signal, that can be sent over the Internet. These signals are then compressed and translated to IP (Internet Protocol) packets for transmission. They are converted to a regular telephone signal, if the user is calling on a normal phone. VoIP gives the provision of making calls directly from a desktop computer and uses a special phone for this purpose. The services and benefits offered by Internet telephony include the ones which are not available with a traditional phone.
The most important benefit of VoIP technology is its cost efficiency, which in turn adds to the savings of consumers and companies using it. Generally, it saves around 30% to 50% of the traditional phone bills, and sometimes more. It may not sound as lucrative for individuals, but if large organizations are considered, the savings can be in the millions.
Internet telephony enables the user to integrate computer applications like email, efax, and web conferencing, with the telephone. It gives the provision of using the phone, while accessing all the other programs, and surfing the Internet at the same time. It is also possible for the users to take the VoIP adapters anywhere, and use their number at any place which offers an Internet connection. This feature is particularly helpful for those with active lifestyles and whose jobs require them to travel a lot. Calls made this way are also relatively cheaper.
Installation of Internet telephony ensures improved productivity of an organization. As the technology is cost-efficient, the money thus saved can be utilized for various other purposes. VoIP technology treats services on the phone like any other kind of data, enabling the users to attach documents to voice messages, or participate in virtual meetings with the help of shared data and video conferencing. The clarity of voice over the phone is also an added feature of the technology. Earlier, talking through VoIP phones often led to calls which were distorted, lagging, and many times, dropped. With the change in technology, the sound clarity is better than ever, and rarely do the calls get dropped.
Simple and Scalable Infrastructure
The installation process for VoIP phones is very simple, and once done, high mobility of the system is an added advantage. The hassles of separate cabling for telephone systems can also be avoided by using this technology. The infrastructure of the whole system is very scalable and new components can be added easily without much difficulty. As the transfer of voice, which is converted into signals is based on software, rather than hardware, it is easier to alter and maintain the whole system. All these attributes makes VoIP more popular, as one does not have to be very good at computers, in order to avail its facilities.
IP Telephony combines voice and data networks onto a single network, creating a more manageable, cost-efficient, and productive solution for business communications. In addition to the above-mentioned advantages, wireless VoIP enables the user to make low-cost calls from any place and also facilitates Wi-Fi. These Wi-Fi spots may include airports, cafeterias, hotels, and various other locations.
