Only one method can be used at a time, with ToS set as the default method. And because your ACLs has the same networks, it allways hit a first rule to change dscp to 46. There was a time when some older network devices would only support IP precedence, and newer network devices would use differentiated services. 11-2016] Best Effort Access Category (AC_BE); therefore, it is RECOMMENDED to map Standard service class traffic marked DF DSCP to UP 0, thereby admitting it to the Best Effort Access Category (AC_BE). The simulated IP phone is sending traffic with a DSCP marking of 46, and will be put into traffic class 5 as expected. If a traffic class has already been defined by using the class-map global configuration command, specify its name for class-map-name in this command.
