best-effort	Indicates that Resource Reservation Protocol (RSVP) makes no bandwidth
	reservation.
controlled-load	Indicates that RSVP guarantees a single level of preferential service,
	presumed to correlate to a delay boundary. The controlled load service uses
	admission (or capacity) control to assure that preferential service is received
	even when the bandwidth is overloaded.
guaranteed-delay	Indicates that RSVP reserves bandwidth and guarantees a minimum bit rate
	and preferential queueing if the bandwidth reserved is not exceeded.

This command is applicable only to VoIP dial peers.

Use the req-qoscommand to request a specific quality of service to be used in reaching a dial peer. Like acc-qos, when you issue this command, the Cisco IOS software reserves a certain amount of bandwidth so that the selected quality of service can be provided. Cisco IOS software uses Resource Reservation Protocol (RSVP) to request quality of service guarantees from the network.

The following example configures guaranteed-delayas the desired (requested) quality of service to a dial peer:

dial-peer voice 10 voip req-qos guaranteed-delay

Command	Description
acc-qos	Defines the acceptable QoS for any inbound and outbound call on a VoIP dial
	peer.
