Provide a brief timeline of TCP/IP-based communications.
What will be an ideal response?
Some years ago, TCP/IP-based communications began to replace the traditional PBX-style phone systems in most organizations. This switch enabled companies to minimize wire installation and enabled developers to get more creative with the gear. Technologies such as Voice over IP (VoIP) made it possible to communicate by voice right over an IP network, even one as big as the Internet. Today, TCP/IP communications encompass a range of technologies, including voice, video, and messaging. On the cutting edge (led by Cisco) is the field of unified communication (UC).
