A voice over IP (VoIP) port is a network port specifically designed for transmitting voice communications over an IP network. It is a logical construct that allows multiple voice calls to be transmitted simultaneously over a single physical network connection.
VoIP ports are essential for enabling VoIP services, which offer a number of benefits over traditional phone services, including lower costs, greater flexibility, and enhanced features. VoIP has also played a significant role in the convergence of voice and data networks, making it possible to integrate voice communications with other applications and services.
