Today, many calls are made over the internet using Voice over Internet Protocol (VoIP). If you use calling apps, video meeting tools, internet-based office phones or browser calling, you may already be using this technology.<br \/>So, what is VoIP? VoIP converts your voice into digital data and sends it over the internet. To understand what VoIP is and how it works, imagine your voice being broken into small data packets. These packets travel through the internet and are reassembled at the receiver\u2019s end so the other person can hear you.<br \/>Voice over Internet Protocol is fast, flexible and cost-effective. However, because it relies on internet networks, devices, and apps, it also introduces security risks. A poorly protected VoIP setup can expose users to call interception, spoofing, phishing, malware links and fraud.<\/div><\/div><\/div><h3>What Is a Voice over IP Phone?<\/h3><div>If you are wondering what a voice-over-IP phone is, it is a phone that uses the internet to make and receive calls instead of traditional phone lines. It may look like a regular office phone, but it connects through a broadband network.<br \/>A Voice over Internet Protocol phone can also be software-based. Calling apps on laptops, smartphones and tablets can work like VoIP phones. These are commonly used for customer support, remote work, business communication and personal calls.<br \/>The risk begins when the device, app or account is not protected. Attackers may misuse weak passwords, outdated apps or unsafe networks to access calls, impersonate users or make unauthorized calls.<\/div><h3>What Is VoIP in Networking?<\/h3><div>It refers to voice communication that travels through a data network instead of a separate telephone network. VoIP calls use routers, internet bandwidth, call servers, IP phones and secure network settings to work properly.<br \/>Since Voice over Internet Protocol uses the same internet connection as websites, apps and emails, network security becomes important. Public Wi-Fi, weak router passwords and outdated devices can put calls at risk.<br \/>For example, using VoIP over public Wi-Fi without protection may expose call traffic to attackers. This is why firewalls, strong passwords, updated systems and trusted security tools matter.<\/div><div>\u00a0<\/div><div><h3><b>Common Voice over Internet Protocol Security Risks<\/b><\/h3><p><span style=\"font-weight: 400\">A Voice over Internet Protocol system can face several security risks.

They may ask users to confirm account details, share OTPs, download remote access apps or click payment links.<br \/>The risk does not always end with the call.
