I got a call from this number and caller id was blocked, it just came up as "Out Of Area". Whoever it was did not leave a message but stayed on the line. I could hear them so this wasn't a robocall. Reverse trace came up as Los Angeles, CA somewhere downtown near 1st St. and Main St. on a landline from AT&T California. This is definitely a scam caller using a spoofed number or a voip call. Definitely block if you can and report to the FTC if you are on the No Call List. Use this form: https://complaints.donotcall.gov/complaint/complaintcheck.aspx
It's not much but it is better to have these people and their numbers on record.
