Got a call from this number a 3:20pm this afternoon to my home phone. No message left as my call blocker rejected it. They have to get permission to get through so this must be a robo call and not a real person.  If it was actually someone I knew and they got a new number, they would email me with their new number or they would have punched in to get through to me and left me a message.  Anyone else gets blocked as I don't know who they are.  Plus, this doesn't seem to be any business number I'm familiar with either.

A Dallas TX area code. Odd exchange "200". Must be junk as my robo call blocker blocked it.

You refer to a "Robo call blocker" - what is that?

We received a call on one of our mobiles at 408P CDT, there was no Caller ID info and they left no voicemail. 214-200 is an active assigned NPA-NXX allocated to Southwestern Bell (now AT&T). We receive intermittent calls on both our mobiles and our home landlines with numbers unknown to us and they leave no voicemails. They are most likely robodialers so they get blocked.

This number called my home number today - no message was left - I actually heard a "hang up" on my recorder.  Showed up as "Out of Area" with a 214 number.
