Caller id NAME using A@H

Does anyone know if A@H can display (or pass) inbound calling party name and number info? I am using a inbound sip trunk feed by a PRI. I have verified that my PRI is sending the calling name and number info. Currently I am using linksys ATA’s on the end of my extentions and have no problem recieving the inbound number. I can see a name come across from extention to extention so I don’t think it is the ATA blocking it. Any idea’s? I do see the calling number in both fields of my caller id phone.
