    I would like to know if anyone knows a way to give extra priority for voice packets over Data packets on any voice enabled Cisco router….



    Checkout the cisco website. Their preferred method at the moment is LLQ/CBWFQ. You can get documents on the cisco website about QOS for voice packets.

    The queuing makes use of Diffserv to prioritize the RTP packets. See RFC 2474/5 for more details.The required IP precedence can be set in your voIP dial peer using the ‘set ip precedence’ IOS command.

    Hope this gives you some pointers.
