Two ways come to mind;

You can use the MQC and a frame-relay map-class...

class-map match-all voip-payload
 match protocol rtp audio

policy-map voip-first
 class voip-payload
  priority 512
policy-map voip-first-parent
 class class-default
  shape average 512000
  service-policy voip-first

map-class frame-relay DLCI_XXX
 frame-relay cir 512000
 frame-relay bc 5120
 frame-relay fragment 640
 service-policy output voip-first-parent

interface Serial0/3/0
 ip address 10.10.10.1 255.255.255.0
 encapsulation frame-relay
 frame-relay interface-dlci 101
  class DLCI_XXX

or the old school ways...

frame-relay rtp priority

map-class frame-relay DLCI_XXX
 frame-relay cir 512000
 frame-relay bc 5120
 frame-relay fragment 640
 frame-relay ip rtp priority 16384 16383 512
 frame-relay fair-queue

and frame relay priority queueing

access-list 115 permit udp any any range 16384 32767

priority-list 1 protocol ip high list 115

map-class frame-relay DLCI_XXX
 frame-relay cir 512000
 frame-relay bc 5120
 frame-relay priority-group 1

interface Serial0/3/0
 ip address 10.10.10.1 255.255.255.0
 encapsulation frame-relay
  no fair-queue
 frame-relay traffic-shaping
 frame-relay interface-dlci 101
  class DLCI_XXX

Keeping digging in the doc cd...
