VoIP services, or Voice over Internet Protocol services, allow users to make phone calls using the internet instead of traditional telephone lines. This technology converts voice signals into digital data, enabling communication over the internet. VoIP can be used on various devices, including smartphones, computers, and dedicated VoIP phones. Many VoIP providers offer features such as video calling, voicemail, and call forwarding, often at lower costs than conventional phone services. Users can connect with others locally or internationally, making it a popular choice for both personal and business communication.
