No Caller ID on Landline Phones & One Converter

Posted about this earlier, no replies. Further tests showing some interesting issues so I am posting a new thread with the hopes that someone may be able to help. I have 3 HD boxes all set to show caller ID on the TV. Two work OK (although they have some days when they don't show caller ID.) One of them - an RNG 150 - does NOT show callers at all. This same box lists as unable to be accessed in the DVR Manager settings tab (SN and MAC info do match in my equipment list.) ... ALSO ... Caller ID on my older Panasonic cordless phones haven't showed ID since I got a new modem for Home Security install. (A technician tried with his test phone and it worked!) However, and here's where it gets interesting, when on a call and I get another (call waiting) call, the phone DOES show the ID of the incoming call. Baffling! Any ideas?
