packets are sent over the IP network. This command should be used if the IP link utilization is high and
the QoS for voice packets need to have a higher priority than other IP packets. The ip precedence
command should also be used if RSVP is not enabled and the user would like to give voice packets a
higher priority over other IP data traffic.
This command only applies to VoIP peers.
Example
The following example sets the IP precedence at 5:
dial-peer voice 10 voip
ip precedence 5
ip udp checksum
To calculate the User Datagram Protocol (UDP) checksum for voice packets transmitted by the dial
peer, use the ip udp checksum dial-peer configuration command. Use the no form of this command to
disable this feature.
ip udp checksum
