I'm freaked out. My LTE Internet Installed Technicolor TG 790 Router with phone service unsupported has been forwarding calls to a number in North Carolina. I find this unacceptable because I have no business in North Carolina and why my router would foward any call, whether by port or phone, is beyond my comprehension. I've been suspecting, detecting and fearing intrusions for months. How can I stop the illegal device access? I'm tired of watching the watcher watch me. Can anyone hear me now?

How do you know its your home router that is forwarding the call? That does not sound like a feature of any home router that I am familiar with. There's a chance the auto forwarding is some feature on one of your individual phones.

More likely that something was misconfigured somewhere. If someone were actively monitoring your communication they wouldn't do so in a way that was so obvious to detect.
Best thing you can do right now is reset the Home router back to the defaults and reconfigure it to your environment. This would wipe out any accidental configuration changes made on the home router level that could be responsible for such a feature.
Next step is to go through and reset your phones to the defaults too. This one takes much more effort and will require you to backup your data first.
Once everything is set back to default and the calls are still getting auto forwarded then I'd start to be concerned about some shenaniganry.
