Companies with existing IP-based WAN links for inter-office voice and data communications can use the 4350 as a traffic shaper to meet the stringent jitter, latency and packet loss requirements for toll quality voice. The 4350 is deployed at the edge of the WAN in both headquarters and branch office locations, as shown below.
