What is IP Telephony?

IP telephony (Internet Protocol telephony) is describing technologies that use the IP protocol to exchange voice, fax, and other forms of information, traditionally carried over the Public Switched Telephone Network (PSTN). The call travels in the form of packets, over a Local Area Network (LAN), or the Internet, avoiding PSTN tolls.

Starting in the mid to late 1990s, the Internet and the TCP/IP protocol began to change the telephone and communications industry. The Internet Protocol becomes the transport for almost all data communications. Today, all communication carriers are using an IP infrastructure for a part or for all of its voice services. With C2 Communications, you can use VoIP for your internal voice communications or you can implement it as part of your unified communication solution.
