Could I provide QoS in voice communications over VPN over Internet ?

When I have in my network dedicated links or Frame Relay links, I can configure QoS for voice connections between the sites if all my switches and routers are Cisco and this function very good. But I tested pass voice over IP communications that PBX send to the router ( E&M and E1 interfaces ) over VPN tunnel over an Internet connection ( DSL ), I have a delay time the 200 ms more or less, but I don´t know How to apply any other feature of QoS in global configuration mode or fastethernet interface ( connection to ISP). I only applied Preference 5 in dial peer, Is There any study case like this ?, I don´t know if the QoS apply in this case.

VoIP over the Internet, is really unreliable. Internet does not guarantee any dedicated bandwidth availability for voice. You might want to take a look at this white paper.

End to End QOS for voice can be achieved by selecting a Multiservice provider who can provide the necessary QOS required for voice transmission.
