Voice over Internet Protocol belongs to a class of internet protocol that enables its user to employ the Internet not only for the purpose of transmission of data but also for conveying the voice information over the same server. For using such type of protocol the equipment that is brought into use is IP telephony that is progressively being implemented in all sized organizations as it facilitates the organization by reducing their overall expenses and assist in enhancing the productivity.
VoIP is defined as an evolving system that represents the advancement in the field of technology. These type of telephone system in mainly used for business purpose to replace the traditional way of communication.
Let us understand some functions of VOIP protocol:
One of the interesting uses of VOIP facility is that it does not require a large scale infrastructure for its operation. All it takes is the connectivity of the internet and IP telephony into one single service with minimal hardware and software support.
For operating the Voice over IP we mainly need a broadband connection. We typically use the broadband connection for services like E-mailing and surfing. VOIP means utilizing the same broadband connection for the purpose of IP telephony.
The connection between an IP phone and a broadband server is primarily done by router sensing the telephone course over an internet connection. This differentiates it from the traditional telephone system as it requires a standard telephone line for making the connection.
A traditional telephone system usually utilizes a PBX function efficiently. VOIP is a data system that is implemented for transfer of voice information over the real time. It is a server which permits its user to connect to their clients directly through this VOIP server that makes the communication process a wireless one and thereby minimize the overall cost of communication.
IP telephony envelops a whole package of services that includes establishing interconnection for telephones, following a proper administration process that includes charging and dialing plans and ensuring the efficient operation of all the services that includes video conferencing, exchange, send, and hold.
Voice over IP is the future way of communication over the internet, and its architecture is primarily developed so that it increases both the efficiency and the effectiveness of the VOIP systems.
