The problem may have fixed itself. For the last 5 days the last 30 calls HAVE displayed the Caller ID on the TV. This was after all suggested solutions failed. More details are in my reply above to WiderMouthOpen
When you don't see the caller ID on the TV, does it still show up on your Cox phone?
What model cable/phone modem do you have?
Do you have any other TV boxes? If so, do those work?
Voice/Internet Modem: Brand: ARRISModel: TM3402A
My Cox landline phone doesn't have a screen, only push buttons.
I only have one DVR. My 3 mini-boxes don't display caller ID.
So we don't know if this is a caller ID issue or a TV caller ID issue. Also, the fact that it sometimes works means it's not a issue with a code on the telephone switch or something. I would suggest contacting Cox and see if they can escalate the issue. Maybe reprovisioning your modem might help. That basically means unassigning the service from the modem and then adding it back on.
Just sent them an email with a link to this and referenced Bruce's post from 7 years ago where an account refresh followed by the user doing an unplug/replug fixed it.. I'll keep you posted.
Cox had me go to preferences on the DVR and highlight COX VOICE, then press OK to turn on. It was already on so I turned it off and then back on. It didn't fix the problem and I reported that to them. They replied "It's possible that the change needed some time to take effect." I just emailed this to them: "The next day 2 calls did not display the Caller ID on the TV, 5 calls did, and I was out of the room on 2 calls and don't know if they did or not. All of them appeared on the Call History Report.and they were all robocalls. The first call today did not display. It’s the only call so far."
Cox Social Media Support & I exchanged emails all day yesterday. They said there is a signal level issue at the box and scheduled a technician visit. I asked if we could first try what has worked for other customers before, for example:
1. "Reprovisioning your modem might help. That basically means unassigning the service from the modem and then adding it back on."
2. "A forum search found an instance of this issue being resolved by Cox pushing out a cable box refresh. But that was years ago."
3. Reply to Bruce 7 years ago, "We've sent an account refresh. At your convenience, please unplug the power to the receiver for 2 minutes. Allow the reset to finish, then check to see if the TV Caller ID banner appears while watching TV and receiving a call." This fixed it for him
I think these are all saying the same thing using different terminology.
So Cox sent a refresh with instructions to wait about 10 minutes after it completed before calling my home phone to see if TV caller ID is restored. After waiting 15 minutes, calls from 2 different cell phones did not display on the TV. But 5 recordings disappeared, which is why I only do daily updates every 3 days.
Then I unplugged the DVR and waited 20 minutes then plugged it in. It finished rebooting in 5 minutes. I waited 30 minutes and a call from one cell phone didn't display but from a second cell phone it did display. I told Cox I didn’t want to pay for a tech visit. He told me their policy is I pay if the problem is not caused by Cox equipment.
So I cancelled the tech visit and installed a 3dB attenuator at the input to the DVR to see if that would help with the signal irregularity. The rebooting process deleted 5 more recordings - - 10 total for the day. It also did NOT fix the Caller ID problem. Previous tech visits have not fixed signal problems either. All they want to do is replace my DVR with a different one that also doesn't work. Complaints in the Forum about this go back over 7 years. Without a reliable Caller ID and reliable recordings I don't need a DVR and might as well go back to AT&T who just installed fiber. I can record TV to my VCR from my antenna.
The problem may have fixed itself. For the last 5 days the last 30 calls HAVE displayed the Caller ID on the TV. I emailed Cox to let them know and asked if perhaps the signal level issue at the box mentioned during our 12/4/24 emails is an intermittent problem and to check it again and let me know.
Raquel replied that she pulled some history on the equipment and although everything appears ok on both devices, this sounds like they may have been out of sync with each other. This is not a reading we can verify after the fact. I let her know that after Cox sent the refresh to the DVR on Dec. 4 and it didn't fix the Caller ID problem, I unplugged then replugged the Cable/Phone modem to see if that would help. It didn't at that time. If the Caller ID problem comes back I'll restart both the DVR and Cable/Phone modem before emailing Cox.
