Hi Joseph,
I tried your first solution in my lab at home today, but when I applied
the class-map to the frame-relay DLCI, I got an the following error
message: "Remove frame-relay traffic shaping first before using GTS in
Modular QoS CLI"
When I first looked at your config, I wasn't sure about having shaping
configured both in the map-class and the MQC. So I tried changing the
service-policy line to call the voip-first policy-map (thus removing the
need for the parent policy) however when I did this the router then gave
a different error: " I/f Serial 0/0/0 DLCI 103 class voip-payload
requested 512 (kbps), available only 256 (kbps).
In order to get around this problem I've configured "frame-relay mincir
512000" within the map-class. Would this be a satisfactory solution to
the original question?
Regards
Chaz

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...
