Configuration Guide For Trunk Side IP PBX Applications
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.
The 4350 performs WAN/LAN IP routing and traffic management functions
in this application. In particular, it provides prioritization to ensure voice
packets are not delayed or dropped while allowing data traffic to use all
remaining bandwidth.
