Enable QoS on Cisco 857

[nickc1976]

Hi,

I would like to enable QoS on a Cisco 857 router so I can give priority to VOIP traffic. I have not done this before, so wondered whether someone could point me in the direction of a good guide on this can be achieved.

I have also read in different places that QoS cannot be fully implemented on the Cisco 857 - can anyone tell me if this is true?

Thanks

Nick

As you read Cisco 857 doesnt support full QoS implementation when compared to the higher models even in 800 series.
