IMHO, whenever you are not requested specifically to trust or not-trust, then not-trust is the safest way to go. This way you know you have control of the proper dscp taggings on the WAN links.
If you do trust, then you must make sure that all devices are sending proper dscp. Eg: mgcp configuration, dial-peer, IOS sccp, ip phones, etc. Additionally in RL, if you trust bindly then you get rogue PCs tagging DSCPs as EF and such.
