Cholzhauer,
Let's start with the basics and work up from there.
1. Does your carrier provide CID Name and Number?
2. System > Flags > Display Caller ID Name and Number set to Yes.
3. System > Phone-Related Information > Flags > Expanded CO Call Information On Displays Yes for every phone.
4. System > Phone-Related Information > Flags > Outside Party Call Information Has Priority Yes for every phone.
5. System > Phone-Related Information > Flags > Propogated Original Caller ID on Transfer Yes for every phone.
6. Make sure that any answer points also have their Propogated Original Caller ID on Transfer set to Yes as well.
When a call comes into a phone you should get some transient information, unless you turned that off at some point, and then it will change to showing the Caller ID Name and Number IF you receive it.
Thanks,
TE
