What is IP Telephony?
IP telephony enables voice communication over internet protocol (IP) networks. It unites an organization’s many locations – including mobile workers – into a single converged network. It promises cost savings by combining voice and data on one network that can be centrally maintained, as well as by eliminating expenses for calls between locations.
IP telephony works by converting voice communications into data packets. Telephones are connected to data ports on the IP network. But the function of a telephone can easily be provided using a device that is already connected to the network – the PC.
The concept of transmitting voice over a data network is exciting to companies that are maintaining intranet connections for all of their branch offices, while paying for voice circuits to PBXs in those same locations. The cost savings alone are appealing, and there are no charges between sites!
