I got a phone call from this number and heard what sounded like a call center in the background then they hung up.

They called informing me about a DOT change and asked for my credit card information

Got a phone call from this number. Didn't recognize, didn't answer.

I got a call from this number, and about five seconds a woman's voice said what sounded like "leven" in a quick, expressionless voice.  When I turned the volume up, I could hear a call center in the background.  Nothing else was said on the call.

Spooky.

Looking at the caller ID posted on an earlier report, I can now confirm that I did take a call from this address this week - they were doing a call campaign for the AMA trying to sell CPT code books.
