Check if "call rsvp-sync" is enabled by default in your IOS version.
If yes then RSVP reservation will be attempted for voice payload:
"Using RSVP means that network administrators do not need to be concerned with port numbers of IP packet flows because RSVP signals that information during its original request."
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fvvfax_c/vvfqos.htm#wp1135779

Also make sure "acc-qos" and "req-qos" are set appopriately:

"Synchronized RSVP is attempted for an IP call when the requested (desired) QoS for the associated dial peer is set to controlled-load or guaranteed-delay, as long as RSVP has been enabled for the interface by using the ip rsvp bandwidth command. If the requested QoS level is set to the default of best-effort, or RSVP is not enabled, bandwidth reservation is not attempted."

Is that what You are asking?
HTH,

Subject: RSVP Question

I haven't used RSVP a lot and I'm confused about how you classify what type
of traffic will be subjected to RSVP.

This config is to reserve 128kbps for VOIP. Assuming that each call can
reserve up to 64kbps. Between Router5 & Router4

But I don't know where in the config voice traffic is marked for RSVP?

Here's my config,

ROUTER5
interface Serial0/0
 no fair-queue
 frame-relay class SHAPE
 frame-relay traffic-shaping
 ip rsvp bandwidth 128 64
!
interface Serial0/0.15 point-to-point
 
!
interface Serial0/0.245 multipoint
ip rsvp bandwidth 128 64

ROUTER4
interface Serial0/0
frame-relay class 405
 frame-relay traffic-shaping
 ip rsvp bandwidth 128 64

map-class frame-relay 405
 frame-relay cir 256000
 frame-relay mincir 192000
 frame-relay adaptive-shaping becn
 frame-relay fecn-adapt
 frame-relay fair-queue

dial-peer voice 1 voip
 req-qos guaranteed-delay

Can anybody help me?

Thanks in advance.

Lee.
