Configuring IP Networks for Real-Time Voice Traffic
Use the procedures in this section only if you have a VoIP feature card installed in your access server.
You need to configure the RSVP for voice, multilink PPP interleaving, and RTP header compression
to improve the voice network performance for your IP network. Some of the options you will use in
the steps listed in Table 3-24 depend on the demands of your IP network.
For a detailed discussion of voice over technology, configuration examples, and commands, see the
Voice Over IP Software Configuration Guide, which includes the following chapters:
•
Chapter 1: Voice Over IP for the Cisco AS5300 Configuration Overview
•
Chapter 2: Voice Over IP for the Cisco AS5300 Configuration Examples
•
Chapter 3: Voice Over IP for the Cisco AS5300 Commands

Step
Command
Purpose
1
5300> enable
Password: <password>
5300#
Enter enable mode (also called
privileged EXEC mode).
Enter the password.
You have entered enable mode when the
prompt changes to

5300# config term
Enter configuration commands, one per line. End
with CNTL/Z.
5300(config)#
Enter global configuration mode. You
have entered global configuration mode
when the prompt changes to

3
5300(config)# int s0:23
Enter the config-if mode. You have
entered config-if mode when the prompt
changes to
5300(config-if)#.
4
5300(config-if)# ip rsvp bandwidth interface-kbps
single-flow-kbps
Enable RSVP for IP for the specified
interface and set the bandwidth and
single-flow limits. If you do not give any
parameters, 75% of bandwidth is
reserved by default. For RSVP to work,
you must configure fair-queuing on the
interface and req-qos in the dial-peer that
points to the IP address of this interface.
5
5300(config-if)# fair-queue
Enable fair-queuing.
6
5300(config-if)# ip rtp reserve lowest-UDP-port
range-of-ports <maximum-bandwidth>
Reserve a special queue for real-time
packet flows to the specified destination
User Datagram Protocol (UDP) ports,
allowing real-time traffic to have higher
priority than other flows. 16384 is the
base UDP port for voice.
