Caller ID Not Showing on TV

Is the cable box the DVR?  If so, on one day the lack of the Caller ID display on the TV was shortly after the Daily Update which reboots the DVR and on another day it was before the Daily Update but did it again after it ran..  I usually skip the Daily Update every day or two and on those days some calls display and some don't.  All calls are appearing on the Call History but there is no pattern on the Caller IDs that might explain, such as when the Caller ID is Spam?+18204002539.  When I made test calls from my cell phone, sometimes the Caller ID shows and other times it doesn't.

Please see my reply above to WiderMouthOpen that I just posted.

I'm not using any type of spam call blockers.  All calls appear on Call History, including calls that ring my phone that aren't displayed on TV & calls blocked by Cox that don't ring my phone or appear on TV.  Calls from all sources have not displayed on TV including robocalls, calls from my 2 cell phones, and calls from my neighbors cell phone and home phone.  But it's intermittent - - sometimes the same number does show on the TV on one call but not the next, or fail to show but do Display on the TV on the next call a few minutes later.  Cox refreshed the DVR at my request.  My email to them included your previous suggestion of reprovisioning but I'm not sure the tech knew what that involved (the actual text I sent is in my reply to WIderMouthOpen). 

On a related subject, you asked once if my recordings only disappeared after a Daily Update.  The answer is only after the DVR is rebooted for whatever reason.  But not after every reboot.  Sometimes nothing is deleted for several updates or rebootings.    I've been keeping a daily log since 8/25/24, and schedule the updates for 8-10 AM so I can monitor how long each step takes and write down what recordings disappear.  I skip 2 days in a row to reduce the chance of disappearances.

I really appreciate your assistance.  Many thanks.

There doesn't seem to be any consistent pattern for calls that display on TV Caller ID.   This won't fix that issue, but have you ever considered just blocking spam calls?  Cox's 'Spam Blocker' prevents calls from ringing, but they still appear in Call History.   See this post.  You can always opt to send spam calls to voice mail instead of blocking them.  The one issue I've found is that verify codes sent to your phone are sometimes blocked as spam.  You may want to temporarily disable 'Spam Blocker' or change from 'Block' to 'Allow' when signing into a website that sends a verify code to your phone.

I originally accepted Cox’s default setting for Spam Blocker but just went there and discovered several things were changed, such as Yes to Voice Mail and Call Waiting.  So I disabled those (I already have an answering machine) and changed Spam Blocker to block high, medium, & low (it was only set to high & medium).  The first 4 test calls from 4 different phones displayed the Caller IDon the TV but the 5th call didn’t.  Regarding verify codes, I haven’t had any problems with them being blocked but thanks for the warning.

'Spam Blocker' may be why some calls aren't being displayed.  Blocked calls don't ring your phone.  I don't think they're displayed by TV Caller ID either.  They're included in Voice Tools Call History but aren't included in Cox TV's Interactive Services > Phone Tools > Call Logs.

"Spam?" started appearing on my Call History in August, 2023.  Caller ID worked properly with my old DVR that died last October and with the new DVR for the first 32 days.  Blocked calls don’t appear on the TV.   I had 6 blocked yesterday and didn’t know about them until looking at the Call History.  The good news is more and more calls are being blocked by Cox.  It’s rare for me to get a second call from the same robo number which is why I didn’t get a call blocker.
