Command Reference Guide
rtp qos dscp <value>

service (QoS) parameters for differentiated services code point (DSCP). Use the no form of this command
to return to the default global value.
Syntax Description
<value>
Default Values

setting for RTP packets. The default global DSCP value for RTP is 46.
Command History
Release 9.3
Functional Notes
By setting the rtp qos dscp value on an individual trunk or user, you will override the global rtp qos dscp
setting for RTP packets. QoS is set using a DSCP value. Valid DSCP values are 0 to 63, and a higher
DSCP value has a higher priority. The default global DSCP value for RTP is 46. Remember that if you are
using a public IP connection, such as the Internet, for Voice over Internet Protocol (VoIP), end-to-end QoS
may not be guaranteed. The default DSCP value for Session Initiation Protocol (SIP) is 26. To configure
QoS for the RTP traffic that carries the voice conversation, use the command ip rtp qos dscp followed by
the desired DSCP value.
Usage Examples
The following example configures the RTP QoS DSCP for trunk T02 to 60:
(config)#voice trunk t02 type analog supervision loop-start
(config-t02)#rtp qos dscp 60
60000CRG0-35E
Configures the RTP QoS parameter for DSCP. Enter a value between 0 and
63.
