Here is what I did to get caller ID to come up on the TV.
I got an Obi 202 with two phone ports and hooked one into my Directv receiver. I have the other phone port into a cordless Dect 6.0 phone system with three other handsets scattered around the house.
Now, when the phone rings, I get caller ID info on the TV. And also on all handsets throughout the house.
I don't know if that would help the OP or not, but it worked for me.
