Who called from 4234905694

Every night at 8:00 CST this # shows up on my Caller ID and it is stacked on each other.
423-490-5694
423-490-5694

I called it back and a woman said they were having trouble with somebody making calls from their line.  
Tonight my husband answered it and nobody said anything and he hung up.

Called at 4:48 pm on a Saturday. No reply to hello, some background noise. Stayed on the phone for a minute, still nothing, then hung up.

Have recieved 2 calls today from this number, both during the naptimes of my 1 yr old son and my sick 6 yr old daughter. Let the machine get the first call, they left no message. Answered 2nd call, heard alot of background talking and laughing, and they hung up on me. Sounds like a fun place to work, partying and making crank calls all day and getting paid for it. [***]!!

have had multiple calls from this number, usually at least twice a day, every day for the past 2 weeks.  never leave message, have never answered call, just see it on call display.  they call in the afternoon and in the evening.

No one was on the phone when I picked up.
