Anyone Else? Humming Sound Over Home Wired Landline?

With POTS (Plain Old Telephone Service), you are technically supposed to take a phone out to the NID on the back/side of your house and plug it in to the test jack.  If you get the buzz there, then the problem is in the line, and AT&T must fix the problem without charge.  If you do not have the problem in that configuration, then the problem is inside your home, and the responsibility to correct the issue is yours; if you ask AT&T to help, it will be on your dime.  You don't have to do this test yourself, but if you let AT&T do it for you, when they find the problem isn't in their lines, they will charge you for coming out to tell you that.

I know of other POTS customers who have your recurring nightmare.  They have the problem, call to get it fixed, wait days to weeks for it to be fixed.  It finally is fixed, only to return 3 or 4 weeks later.  Rinse.  Repeat.  For this lovely service, AT&T now charges over $50/month.  I didn't have this situation myself, when I had line noise issues, BellSouth corrected it in a matter of a day or two. [Yes, it was that long ago.]

The $50/month made me switch my home line to a VOIP provider over a year ago.  I get caller ID included, SPAM filtering included, voice mail included, plus other features I'll rarely use, for about half what I would be paying AT&T.  AT&T doesn't want to be in the POTS business anymore.

Thank you Jeff! Your assessment is quite correct here. So, since already filing the trouble report ticket days ago via AT&T online trouble reporting, I now repeatedly get TEXTS to my mobile contact number. AT&T is asking if I still wanted the repair technician out to my home to further investigate? What does this mean? How would the humming or buzzing miraculously go away? Apparently, some kind of wired landline testing has been done as indicated. i.e. "under investigation" or something similar. I'm confused as their communications isn't really that clear to me. In conclusion, I hope you're happy with your VOIP services dependent upon good reliable internet speeds. I hear that fiber optic networks have provided much faster upload and download speeds. I've considered this strongly though. It maybe much better for internet, VOIP and streaming and live TV.

I actually sprang for a package that allows me to use either Internet (which I do now have AT&T Fiber, and it's great 99.99% of the time), or T-Mobile LTE for the connection.  That costs another $12/month, but the whole thing is on par with the cost of a cell phone line and I have redundant paths to the network.
