Voice Over Internet Protocol System

VoIP stands for Voice over internet protocol. It refers to the transmission of voice traffic over an internet connection. It can be defined as the system of making phone calls through the internet, as opposed to an ordinary landline or mobile phone. A VoIP framework takes your voice signals, changes them into digital ones, and then sends them over your broadband line. VoIP phone system gives complete integrated communication.

How Does VoIP Works?

VoIP phone systems first convert a voice call into a digital signal, then transfers it through the internet as a non- VoIP Number, and then transforms it into a telephone analog signalVoIPvoIP phone call can be made out with any devices like computer, private phone or any other but it must relate to VoIP adapters. When a VoIP phone gets the digital information from a new device, it breaks the data into data packets and puts a destination address on all the boxes. After that, all the converted data is sent over a broadband line to the router. As the router receives the information, it will look for the shortest way to reach the destination address. The packets may pass through various routers to optimise the final route and receive the packet at the destination address. The accepting VoIP phone then uses the lessons for each packet to put the packets in the correct order. The VoIP operator then receives the data in an identifiable language. In VoIP business over a telephone system, a co-worker can use an office internet connection to connect their telephone network. A voice signal is broken into tiny data packets in a VoIP phone system. Long-distance calls are cheaper in VoIP systems. The network diagram for VoIP is shown below.

While VoIP has many advantages, similar to everything, it has a couple of disadvantages too, and they all connect with it being dependable under particular conditions. Some of the disadvantages of VoIP are

• VoIP is dependable on internet connection: VoIP systems are completely internet-based systems. So, you must have a strong internet connection with higher bandwidth and ensure your bandwidth can carry your VoIP service. If there is high internet traffic, it will affect the quality of calls.
• Potential Malware attacks: VoIP is vulnerable to various attacks such as Man in middle attacks, Call Tampering, Spamming over internet telephony, Denial of service, Viruses, and Malware. In Man in middle attacks, the attacker intercepts call signalling SIP message traffic and masquerades as the party’s calling party, and vice versa.
• Difficulty during Emergency calls: VoIP uses an IP address as a Phone number, and the exact geographic location cannot be traced with an IP address. If you are using traditional PSTN lines and you were not able to tell your address to the emergency operator, they can easily trace your address and help. Still, with VoIP, there is no way to find the caller’s precise location if they cannot tell the operator their address.
