Use the ip prece<strong>de</strong>nce command to configure the value set in the IP prece<strong>de</strong>nce field when <strong>voice</strong><br />

data packets are sent over the IP network. This command should be used if the IP link utilization is<br />

high and the QoS for <strong>voice</strong> packets need to have a higher priority than other IP packets. The ip<br />

prece<strong>de</strong>nce command should also be used if RSVP is not enabled, and the user would like to give<br />

<strong>voice</strong> packets a higher priority over other IP data traffic.<br />

This command is applicable to VoIP peers.<br />
