4. You will move to the VoIP Traffic Matching window, in which you specify
how the router will identify VoIP packets:
a. The documentation for your VoIP application may include the UDP
real-time protocol (RTP) port or ports to which traffic is sent. Select
RTP and enter the range of ports in the Start Port and End Port fields.
If this range includes odd ports, check the Enable Even and Odd Ports
box.
b. If your VoIP application marks traffic with a ToS value, you can
configure the router to select traffic with this value. The router can
select traffic according to either DiffServ or IP precedence:
– Select DSCP and enter the DiffServ value used by your VoIP
application. You can also accept the default value 46 (for expe-
dited traffic).
