Okay so when I call my home phone number (which is a TWC/Spectrum number) from either of my two tmobile pay as you go phones, which are two different numbers on two different phones, instead of the home phone recognizing the numbers as mine through its caller ID like it normally does, it states they are an "unavailable unknown number". I just noticed this problem today. As far as I can be sure it worked correctly a week ago.
Actually the way the problem started (today) was that I was first getting a recorded message after dialing my home phone number from my tmobile phones stating that the number I was trying to reach (my home phone) does not accept calls from callers that block their number (words to that effect).
So I went into my Spectrum/TWC account and changed the call blocked plus/basic from plus to basic so this way my phone call would get through to the home phone because my home phone seems to be treating my two tmobile phones as having their caller id shut off - which they don't.
Now the calls can get through but as first stated my home phone won't recognize my two tmobile phones and states they have an unavailable unknown number. Also, note, the handset that handles my home phone has both of these numbers stored in its phonebook as well.
I also just noticed my friends tmobile phone is doing the same when he calls the line.
I have another cell phone that has tracphone service, and that is recognized by my twc/phone handset correctly.
I did call tmobile to ask about it and they looked at my account and they say that there are no caller id blocks on the account. We went through the phone settings and all settings were set appropriately and the phones themselves (LG 450, and a Lumia 640) have no number block on it with call reject off and the list empty of numbers and send my number is set correctly. Also, If I call other phones with the tmobile phones, the caller id on those phones identifies my phone through the caller ID they have. It is only when I call my home phone - the spectrum/twc number - that the numbers are unrecognized and treated as if they have caller ID shut off/disabled.
I have asked about this at the TWC forum as well. I'm not certain of the origin of the problem since other cell phone providers do give their caller ids to the TWC home phone and as well, the tmobile phones are giving caller id to other phones - cell phones. So both seem to work right as long as it is not with each other.
Thanks for any assistance.
