CISCO QOS BETWEEN 1801 and 877

Thanks for the reply, what you have put has helped greatly in understanding how you impliment the QOS on the routers, looking at your comment you suggest a access list entry can be set up to show the destinations for both the to and from locations. This would probably be the best way of going about this from our customers perspective. I have never had any expieriance in setting up QOS and very little expieriance with VOIP and I am still waiting for more information from the phone company that have installed the phone system that requires the QOS between the two sites as to if the communication for VOIP goes between the two main phone systems and is then presented out to the users phones or if the calls go direct from one phone to anothwer via ip address. Once I have this I should be ablke to supply a definative answer on how to identify the QOS traffic. If possible though could you show me how I would do this using access lists as the identifying factor.

I'll try to help any way I can.   If you can tell me more about the specifcs of the phone systems, the IP addressing, and overall architecture, this should be a pretty easy task.
