When configuring "frame-relay fragmet..." the IOS uses dual queue on the interface.

From the point of view of voice quality, is the sound as good as other methods of prioritization, for example LLQ? (does not have a FXS to test; thanks to any feedback).

r3#sh queueing interface serial 0
Interface Serial0 queueing strategy: priority

Output queue utilization (queue/count)
        high/19 medium/0 normal/160034 low/0

The configuration is:

interface Serial0
 encapsulation frame-relay
 frame-relay traffic-shaping
!
interface Serial0.34 multipoint
 ip address 172.16.34.3 255.255.255.0
 frame-relay class TaskQos
 frame-relay map ip 172.16.34.4 304 broadcast
!
map-class frame-relay TaskQos
 frame-relay cir 64000
 frame-relay bc 640
 frame-relay be 0
 no frame-relay adaptive-shaping
 frame-relay fair-queue
