Precedence is automatically given to traffic coming from IP phones and other devices using the 4300T’s Application Layer Gateway function. NAT/PAT translation for IP phones and PC’s. This allows a single IP address to be used on the WAN link to represent all of the private IP addresses assigned to the LAN IP phones and PC’s.
- Page 15 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 4300T as a traffic shaper to meet the stringent jitter, latency and packet loss requirements for toll quality voice. The 4300T is deployed at the edge of the WAN in both headquarters and branch office locations, as shown below.

For normal operation the setting should always be No Loopback (the default setting). Configure the DHCP Server The 4300T can act as a DHCP server granting IP addresses to PCs, workstations, servers or voice devices (IP phones, IADs or softphones) connected to its LAN interfaces. - Page 22 IP phones. Some IP phones use these values for configuration of their TFTP server and MGCP control server addresses. PLEASE note: The DHCP server in the 4300T should not be used if a DHCP server already exists in the same subnet as the 4300T. Also, it is recommended that you assign static IP addresses for common-access devices such as network printers or fax machines.

WAN and the LAN. TOS bits are used so that VoIP packets can be prioritized in the network by DiffServ enabled routers. The TOS bit value used by the 4300T is to “minimize delay and maximize throughput”, or 0xb8 hexadecimal. This value is set for all VoIP packets processed by the 4300T and overwrites any specific TOS bit configuration set by VoIP endpoints. -
Page 38: Enable Traffic Shaping
Enable CAC The 4300T uses CAC to limit the number of active voice calls over the WAN link. This is necessary because a typical installation uses a ratio of 1:2 or 1:4 active voice calls to voice devices on the assumption that 50% or 25% of all users are on the phone at the same time. - Page 39 PBX. If the PBX is responsible for this setting you do not need to configure CAC in the 4300T. Please check with your IT administrator to determine if this is the case. PLEASE note that CAC is available in the 4300T for the MGCP and SIP VoIP protocols only.

Traffic shaper: To smooth bursts from high speed data links (typically from the LAN Ethernet heading to the WAN) the 4300T appliance uses a buffer that clocks data out at rates not exceeding automatically-calculated maximums. Low-priority data is clocked out at the WAN link’s full rate LESS the bandwidth currently being used for high-priority... - Page 41 (then dropped if necessary) before being forwarding on to its LAN interface. Similarly, data traffic sent back to the 4300T for transmission to the WAN are also delayed (as described in the above section). This results in the WAN-based devices following the rules of TCP/IP congestion avoidance and slowing down their transmit rate.
