We always use DSCP 46 for voice - almost every manufacturer is good with that setting.  A chart from Cisco follows.  Cisco also provides an option for auto-QoS, but some of the choices it makes can be limiting, so we prefer the manual settings.

Commonly Used DSCP Values

DSCP Value   Decimal Value       Meaning
101 110             46             High Priority Expedited Forwarding (EF)
000 000             0             Best Effort
001 010             10             AF11 Low
001 100             12             AF12 Medium
001 110             14             AF13 High
010 010             18             AF21 Low
010 100             20             AF22 Medium
010 110             22             AF23 High
011 010             26             AF31 Low
011 100             28             AF32 Medium
011 110             30             AF33 High
100 010             34             AF41 Low
100 100             36             AF42 Medium
100 110             38             AF43 High
