19.1.3.3 SIP WAN to Any Bandwidth Management Example

the same as the SIP Any to WAN policy, but with the directions reversed (WAN to
Any instead of Any to WAN).
19.1.3.4 HTTP Any to WAN Bandwidth Management Example
• Inbound traffic gets more bandwidth as the local users will probably download
more than they upload (and the ADSL connection supports this).
• Second highest priority (2). Set policies for other applications (except SIP) to
lower priorities so the local users' HTTP traffic gets sent before non-SIP traffic.
• Enable maximize bandwidth usage so the HTTP traffic can borrow unused
bandwidth.
