An IP phone leverages VoIP technology, enabling users to make and receive calls via an internet connection. This serves as a modern alternative to traditional landline systems, which generally rely on the Public Switched Telephone Network (PSTN). By moving away from legacy systems, IP phones provide organizations with versatile communication solutions, facilitating calls over the Internet. They can also function as conference phones, allowing seamless connectivity across the organization. These VoIP devices transform analog voice signals into digital data packets, transmitting them over broadband connections. There are two main categories of IP phones: purpose-built and software-based. Purpose-built VoIP phones resemble standard conference phones and connect directly to the internet, while software-based options can be utilized on desktops, laptops, and mobile devices with peripherals like headsets or microphones for internet-based communication. For optimal performance, it is advisable to choose IP phones from reputable brands such as Cisco, Polycom, 3 Com, Ubiquiti, HP, Dell, Panasonic, and Mitel Networks.
