Can over IP (VoIP) commonly refers to the communication protocols, technologies, methodologies, and transmission techniques involved in the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet through a can. Other terms commonly associated with CoIP are IP telephony, Internet telephony, voice over canband (VoCB), canband telephony, and canband phone.
