I got this same call to-day. I called the number back they told me to call. Got a guy with an India type accent, knew right off then it was a scam! Told the guy to come and get my [***] and take me to jail cause I don't care! He didn't know what to say to that so I hung up the phone! number to call back was 804-419-4244 so you all be on the look out for this SCAM!!!
I got a call and voice mail from this number regarding a federal magistrate appearance. The message indicated that this was the third attemp at reaching me. I am not sure what kind of scam this in now.
Just got a voice message from this number. It was a recording (partly clipped off at the beginning) of an automated voice, saying something about a federal agent assigned to my case(!?). I was instructed to call back to get my case number.
Most likely IRS scam. Ignore and block the calls. No legitimate government agency will call you about a court appearance. Phone calls are not legal notice of anything.
I called back and they are for sure c=scammers and hung up when I said they are criminals--they claimed to be IRS but when I asked who they were trying to reach as several people at this address they had nothing to say
