Information About Cisco Unified SRST 7.1
To configure Cisco Unified SRST 7.1 features, you should understand the following concepts:
•DSCP
•Voice Translation Rules and Profiles
DSCP
Differentiated Services Code Point (DSCP) packet marking is used to specify the class of service for each packet. Cisco Unified IP Phones get their DSCP information from the configuration file that is downloaded to the device.
In Cisco Unified SRST 7.1 and later versions, you can configure the DSCP value for media packets in the configuration file for SCCP phones. Because Cisco Unified IP Phones get their DSCP information from the configuration file that is downloaded to the device, the DSCP value for other types of traffic is set by Cisco Unified Communications Manager in the configuration file it downloads to the phone.
For configuration information, see the "Configuring DSCP for Cisco Unified SRST" section.
Voice Translation Rules and Profiles
Voice translation rules perform manipulations on telephone numbers. Voice translation profiles allow you to group voice translation rules together and use them to manipulate the calling number (ANI), called number (DNIS), or redirected called number for a voice call.
Translation rules are defined by using the voice translation-rule command. After you define a set of translation rules and assign them to a translation profile using the voice translation-profile command, you can apply the rules to all inbound or outbound calls to and from a specific SIP phone, or to individual inbound or outbound call legs according to the directory number.
For configuration information, see the "Applying Voice Translation Rules in Cisco Unified SRST 7.1 and Later" section.
How to Configure Cisco Unified SRST 7.1 New Features
This section contains the following tasks.
•Configuring DSCP for Cisco Unified SRST
•Applying Voice Translation Rules in Cisco Unified SRST 7.1 and Later
Configuring DSCP for Cisco Unified SRST
To set the differentiated services code point (DSCP) levels for phones, perform the following steps.
Prerequisites
•Cisco Unified SRST 7.1 or a later version.
Restrictions
•Cisco Unified IP Phones get their DSCP information from the configuration file that is downloaded to the device. Because Cisco Unified SRST does not download configuration files to phones during fallback, only the DSCP value set for media packets takes effect, and only for SCCP phones.
•If DSCP is configured for the gateway interface using the service-policy command or for the dial peer using the ip qos dscp command, the value set with those commands takes precedence over the DSCP value configured with this procedure.
SUMMARY STEPS
1. enable
2. configure terminal
3. call-manager-fallback
4. ip qos dscp {{number | af | cs | default | ef} {media | service | signaling | video}}
5. end
DETAILED STEPS
Examples
The following example shows the DSCP value for media is set to af11.
call-manager-fallback
ip source-address 10.10.10.1 port 2000
max-ephones 100
max-dn 240
ip qos dscp af11 media

Applying Voice Translation Rules in Cisco Unified SRST 7.1 and Later
To apply a voice translation profile for incoming or outgoing call legs to a directory number on a SIP phone, perform the following steps.
Prerequisites
•Cisco Unified SRST 7.1 or a later version.
•Voice translation profile containing voice translation rules must be configured. See the Configuring a Translation Rule section in the VoIP Gateway Trunk and Carrier Based Routing Enhancements document.
SUMMARY STEPS
1. enable
2. configure terminal
3. voice register dn dn-tag
