The calleriddetection is used only for anlog tenor, not digtal. I believe that it says this in the guide. You want to make sure that the relayani setting is enabled. This can be found in the isdnsignalinggroup and the IProutinggroup and the cassignalinggroup.
I am not sure I understand your flow, it appears that the calls comes from E1 to quintum then IP to your WellSip. So if the relayani is set correctly, then next thing to check is to make sure that the quintum is getting the ani from the E1 line (hopefully ISDN, not R2).
