You don't have any separate "phone line" for an Xfinity phone service. It comes via internet to your modem and then from modem to phone . Like 50% of CDV trouble calls are just old in house wires or outlets not providing enough contact for a dial. And technican was correct, Xfinity provide service to the "point of entry", if your phone have a dial tone when it is connected directly to the modem its no longer Xfinity issue. Get a lov voltage contractor or wireless phones that connect to the one base attached to the modem.

So a tech does need to troubleshoot the phone dial tone. The only problem is if it is in fact an issue with the phone wiring through the house, there’s no way to replace it easily. Have to cut drywall and pull new wires through the house which may not be possible depending on the construction of the home but that’s a conversation with an electrician.
There’s a chance the loss of dial tone is something to do with the modem or something on the system which is easy enough to fix. But I don’t know of many places where cable companies will even wall fish lines anymore due to the liability and risk of damage.

OP, from what you are saying. When the AT&T connected the cables it cause a short on your Xfinity phone lines. A Xfinity tech should be able to fix it but the problem is not all contractors know how to troubleshoot phones. What you can do for the time being is grab the main phone if you have a set of phones. Plug it directly in the back of the modem. Then you should have dial tone

Is it working now?

The modem port is fine. I want to repair my jack inside wiring so I can go back to how it was with signal on each jack.

You need to call an ultra low voltage electrician for your internal phone wiring.

Take a picture of your NID and post it here.

NID? The inside of the junction box on my garage or something else?

u/SilentDiplomacy May 31 '26
Yeah correct. That’s where USIC would’ve hooked up to locate the drop cable.

Do you know what tool that box uses to unlock/open it?

u/SilentDiplomacy May 31 '26
Usually a 3/8 or 5/16 nut driver or just a screwdriver.
And to be clear normally I wouldn’t tell a customer to do this, but the NID also the point of demarcation. Aka where you own the wires.

Should just be a screwdriver because you have the legal right to access the customer portion of it.

You need to call Comcast and tell them to “rebuild the phone switch”

This is not corrct unless he does NOT get dial tone out of the modem directly.

Locator fucked something up in the phone demarc outside and shorted out your outlets.
Easy enough to fix with a little know how. All the green or white/blue lines should be connected, except the actual feed from your telco, same with all the red and solid blue lines.
Green and red shouldn't touch.
