I answered with my company's name and my first name "Tom".
A man with a mild Indian accent spoke my first name, "Thomas?", I said "Yes?" and he promptly hung up. A call back to the number resulted in a fast busy tone.
Common scripted callers, from a thrid workld country. They gather employee names and voice samples of each employee for use later for illicit purposes. NEVER USE THE WORDS "YES or "NO" IN THESE CALLS
