VoIP, or Voice over Internet Protocol, is a technology that allows people to make phone calls using the internet instead of traditional phone lines. This means that your voice is converted into digital data, which is then transmitted over the internet. VoIP can be used on various devices, including computers, smartphones, and specialized phones, making it a flexible option for communication. One of the main advantages of VoIP is its cost-effectiveness. Since it uses the internet, long-distance calls are often cheaper than those made through traditional phone services. Additionally, VoIP services often come with extra features like video calling and voicemail, enhancing the overall communication experience.
