VoIP Phones (Voice over Internet Protocol Phones) are IP-based communication devices that transmit voice and multimedia signals over data networks using internet protocols instead of traditional PSTN or analog telephone lines. These phones connect to IP PBX systems, SIP servers, and cloud-based telephony platforms, enabling efficient, scalable, and cost-effective voice communication.

VoIP phones support advanced calling features such as HD audio, call transfer, conferencing, voicemail, caller ID, and directory services, along with secure communication using encryption protocols. They are easy to deploy, centrally managed, and ideal for modern enterprise and unified communication environments.
