Cisco IOS h323 voice gateway and QOS

I've got some 12.3.1 voice gateways out there and when doing sniffer traces I see my callmanager IP phones talking to the gateway and the packets are marked with the correct IP Precedence bits (5)...

when the gateway talks to the phone, it's being marked with IP Precedence 0... how do I force the gateway to mark the IP precedence bits correctly for the return traffic?

Thankx!

On your outbound voip dial peer, add the command :

ip qos dscp cs5
