VoIP (Voice over Internet Protocol) is a technology that enables the delivery of voice and multimedia content over the internet. VoIP systems allow people to make voice and video calls, send instant messages, and share multimedia content, such as audio, video, and images, through their internet-connected devices, such as smartphones, laptops, and desktop computers.

VoIP systems can be classified into two main categories: consumer VoIP and business VoIP. Consumer VoIP services are typically free or low-cost and are used for personal communication, such as making voice and video calls with friends and family. Business VoIP, on the other hand, is designed for organizations and provides a range of advanced features, such as auto-attendant, call forwarding, call queuing, and more.

VoIP systems offer many benefits, including cost savings, flexibility, and improved communication. Unlike traditional telephone systems, VoIP does not require dedicated hardware and can be easily set up and managed through software, making it a highly scalable solution for businesses of all sizes. Additionally, VoIP systems can be integrated with other communication and collaboration tools, such as video conferencing and instant messaging, to enhance communication and collaboration among team members.
