Voice over Internet Protocol, or VoIP, enables computer users to make phone calls via the Internet without using a traditional telephone line. This is made possible by a variety of listening ports and hardware ports on a computer. Two primary types of listening ports are used: Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). TCP ports are commonly used in VoIP transmissions, while UDP ports are used for administrative purposes such as resolving server conflicts and upgrading products. In additionally, VoIP phones require hardware ports for the use of accessories such as handsets and headsets. Writer Bio
