Just an update, my Frontier home service was restored Tuesday, four days after reporting it.
The tech came out checked the ONT, replaced the ONT. I said I was sure it was a CO problem, he said nope, I told him the voice mail wasn't working, he said it is now, he had seen that in the ticket and "deleted and rebuilt" my account, and had fixed that remotely before he came out. So if I had kept calling I might have gotten them to get line working enough so people calling would go to voicemail.
So the phone support hardware in the ONT failed without an internet outage. And my account got scrambled along the way.
At any rate he was talking up the Wavedivision acquisition of parts of Frontier. And that some of that happened that Saturday and was still a work in progress. He said he couldn't call ahead yet to customers for some reason. I mentioned that I was getting texts from Frontier, and he said there was an agreement for Frontier to provide customer support for 3 years as part of the deal. I guess we will see how that works out.
Now to look at where to port out to.
ETA that joke about telemarketers? It may be coincidence, but the phone has been a lot quieter lately.
