Got a call this morning.  When I called back, there was no answer, or voicemail.

Same here. Nothing.
It must be the "newest scam" using the "newest scam phone number" because we are starting a new thread on this number.
Just be careful you do not get charged for your call back to them. That seems to be the new thing. Sometimes best to not even call back.

I have answered they claim to be a civil procedure department.  they have been calling my phone looking for my numbers previous owner.  when you tell them not to call,  or that you are not the person they are looking for they just hang up.   I have called back as well to talk to a supervisor and no answer .  so annoying as this happens daily

Called wanting to know if will be home to have papers served.  I just hung-up.

Received two calls from this number, I do not answer calls for numbers I do not know or anyone who does not leave a message. Seems like a scam, people do not call to let you know they are serving papers on you. It seems like an extortion method to get you to pay money. Call your local Police Department and save the message and report to them or you local Attorney General, Sheriffs Department. If you get a call from them again, give them the numbers for local PD, Sheriffs Department and Attorney General's office. File a complaint with the FTC online.
