Voice Over IP Products

4000 17 Slot 6U Cardframe

Overview

Voice over Internet Protocol (Voice over IP, VoIP and IP telephony) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).

Case Communications VoIP products provide both PBX facilities and routing, along with a number of advanced features such as Transporting HDLC and DPNSS Over IP, as well as converting between various legacy systems, allowing customers to keep their existing telephony systems and operate over an IP Network.
