3. From the 'Device' drop-down list, select 'Default WAN device', and then click OK; the
following page appears:
Figure 3-14: Defining Traffic Shaping
4. Under the ‘Tx Traffic Shaping’ group, specify the total WAN bandwidth (in Kbps)

shown in the figure above.
5. Click OK.
3.2.1.5.2 Defining VoIP Tx Traffic Shaping Classes
Once you have defined the total bandwidth allocated to the device's WAN interface, you
need to define a traffic shaping class to reserve a minimum bandwidth (e.g., of 1 Mbps) for
Tx VoIP traffic (SIP signaling and RTP packets) out of the total bandwidth (e.g., 5 Mbps).
¾ To define traffic shaping class for VoIP traffic:
1. Open the ‘Traffic Shaping’ page (refer to 'Defining Total WAN Bandwidth' on page 50),
and click the Edit button corresponding to the 'Default WAN Device' entry.
2. In the 'Tx Traffic Shaping' group, click the New
button.
Figure 3-15: Adding Shaping Class Name (for VoIP Tx Traffic)

and you are returned to the previous page.
