They are talking about phone lines it's a scam

Did not answer as number is not recognized by me.

The caller was trying to sell me a security system and they asked if I owned my home and I said yes, then they said hold on and the line went dead.

Scam!! They call everyday and finally today someone on their end said something, they usually sit there and never say anything and just hang up! They said they are calling about my home alarm equipment. Funny thing, we don't even have an alarm!

Nobody ever says anything, they just hang up.
