In the delivery of voice communications and multimedia sessions, various technologies are utilized. Under this case, Voice over Internet Protocol (VoIP) is one of the common technologies that are utilized in the execution of this particular task. The technology operates on a basic principle of converting analog voice signals into digital data that become easier to be transmitted via a network. The technology utilizes phones as a physical device that is installed on a system. Additionally, the technology can also utilize a software program that is installed on a computer that uses microphones and speakers for digital conversion. In the current century, most individuals have already interacted with various kinds of VoIP technologies. For example, Skype is one of the common VoIP technologies that is used by millions of people across the world. Importantly, VoIP technologies are vital in small and large business enterprise, like in Essays.Solutions and government.
In initiating VoIP communications calls, Session Initiation Protocol (SIP) is used as a standard measure. The call initially commences with the initiator dialing a predetermined number that sends an invite to the designated proxy server. In this case, the proxy server is also termed as a gatekeeper. Once the proxy server receives the invitation request, it relays trying a response to the caller to stop the transmission to further multiple invites. At this juncture, the gatekeeper now commences searching for the address of the receiver it had relayed the invitation requests. The moment the invite is received, there is the generation of a ringing response that is communicated back to the initiator of the call. Afterward, the initiator sends an acknowledgment packet to the receiver. During this duration, a session is established, and both phones begin to communicate directly with both receivers on either end. Once the call reaches to an end, BYE request is sent to terminate the VoIP session where the call termination can occur at any end. Once the BYE request has received the party that receives it initiates a follow up by sending an OK response. However, in some cases, some systems are designed to update the proxy server with the status of the call via the session tracking response and process.
In the current times of technology revolution, VoIP technology has become very popular because of affordability. The fair prices are influenced by a variety of ways that encompass;
However, since VoIP is sent over internet protocol (IP), it is possible to bypass hefty calling rates that are provided by a typical telephone services corporation for long distance and international calls. The fact that VoIP can be piggybacked on existing network equipment no additional hardware is required for completion of the task. Importantly, the VoIP technology can be cheaper in the instance when the user is utilizing a computer as a softphone. Under this case, the VoIP shares the same equipment and cabling as the computer traffic thereby reducing maintenance cost as single equipment is used. The technology is reflected by the current phones that are being manufactured in the 21st century.
