Phone Line Hacked?

New Poster

Phone Line Hacked?

We have two AT&T Cordless Phones in our house, we have been mysteriously seeing the primary phone lighting up and saying "Line In Use" when we are not on either phone.  If we pick up the phone we can hear dialing and then a "click" like someone knows we are on the line and hangs up.  How is this possible, can someone hack into our phone line through Comcast, or are they possibly using the cordless phone frequency?

*Update*

 

This has happened 5 times since my post. 

 

When it does, we turn our phone on speaker and we hear the sound that someone has dialed a number and it's ringing, then it picks up on the other end with a few computer beeps, then it dials another number, and you hear what appears to be a modem or fax machine picking up.

 

Not sure what this could be, but I think someone is using our phone line somehow.  Any one have any ideas?

Re: Phone Line Hacked?

Many times it's from automated equipment in your home plugged or wired into your phone wiring like

 

Tivo DVR's

 

Alarm Systems

 

Fax machines, or fax modems in a pc or Mac.

 

Water meter - I had two homes that the water meter was tied to the phone line for billing.

The only thing on that list that would be plugged into my phone line is the house alarm, I'll look into that, but it's not calling anything that I know of.  Thanks for the input.
