AutoQOS on core switch

Hello, I have this scenario, hope somebody can help me.

Core switch <-----------> IP Tel Switch <------------>phones      

1                             2                                  3  

                                       .

                                       .

                                       .

                                       .                 

                     <-----------> ...........                                  ............                                                 

                                           xN                                     xN 

All the switches are 3750-v2 and phones are from cisco.  Only one core.

This is the current behaviour:

2 trust cos from 3

1 trust cos on trunk from 2

I configured intervlan routing on 1. Do i need to trust dscp on both the interface vlans on 2 and 1? 

thanks for your precious help
