Who called from 2148183800

I received a call from this number from a fast-speaking man saying he was calling on a recorded line. I told him I would call back. Checked the number and decided not to

called back and continuously busy.

Call showed up as 214-818-3800 from Dallas. Left a voicemail and gave her name.  She said she was from the Lockheed Martin Service Center, and who she was calling for (wrong number), but left a callback number.  This was legit this time.

This number from Lockheed Martin Retirement center. Legit number.

Maybe so, but someone could be spoofing their number on the caller ID
