I have a Cisco 887 which is being used for voip and data, however I need to get QoS applied to reserve bandwidth for the voice.

I have tried to use class map and policy map but with no success

class-map match-any VOIP

match protocol rtp

!

!

policy-map VOICE

class VOIP

  priority 100

interface Dialer 1

service-policy output VOICE

But when I try to apply this the interface Dialer 1 i get an error

Insufficient bandwidth 56 kbps for bandwidth guarantee

Can anyone advise on how to get this working

Thank you
