Voice Over IP (RVP__Over_IP) 
Voice over 
IP 
(VoIP) 
A network connection allowing voice packets to be delivered to the alternate site 
using the Internet Protocol (IP). In most IP circuits two types of devices are utilized. 
A server (PBXgateway) is the main hub of information being requested, and a client 
(the Remote unit) or user obtaining the information. The Remote unit receives the 
voice packets from the user phone and transmits the packets via the LAN and 
sends them over the WAN to the PBXgateway at the corporate facility.
