An IP PBX (Private Branch Exchange) is a business telephone system that uses Internet Protocol (IP) to transmit voice, data, and video communications over a computer network, rather than traditional analog phone lines. IP PBXs offer a number of advantages over traditional PBX systems, including:
Lower costs: IP PBXs can be significantly less expensive to install and maintain than traditional PBX systems. This is because IP PBXs use standard computer networking equipment, which is much less expensive than the specialized equipment required for traditional PBX systems.
