Telephony over IP (ToIP)

Telephony over IP (ToIP) refers to the transport of voice, video, text, and other real-time media over ▲IP networks. IP Telephony is considered to be the key technology that will provide advances in communication for end users and is expected to completely replace the ▲PSTN over time. This term is synonymous with ▲VoIP, though some people like to say that "telephony" is more encompassing than "voice", meaning that "telephony" includes functionality beyond "voice".
