IP Telephony

The essence of communication is breaking down barriers. The telephone, for instance, breaks distance and time barriers so that people can communicate in real time or near-real time when they are not in the same place. But as communications evolve, there are new barriers to be overcome. New forms of communication emerge, such as e-mail, voice mail, fax machines, and pagers, and people use different devices for each of these.

Unified messaging (UM) is designed to overcome these barriers. It breaks down the terminal and media barriers so that people using different technologies, different media, and different terminals can still communicate with anyone, anywhere, at any time. Unified messaging is the integration of several different communications media so that users can retrieve and send voice, fax, and e-mail messages from a single interface, whether that is a wireless phone, a PC, or an Internet-enabled PC.

IP telephony provides a way for you to extend consistent communication services to all your employees, whether they are in main campus locations, at branch offices, or working remotely, or are mobile. IP telephony transmits voice communications over a network using open-standards-based Internet Protocol.
