Who called from 2147717573

Received phone call. Did not answer.

Called my cell during lunch. Hung up very quickly - voice mail did not have time to answer. Dallas metro number.

called and hung up before forwarded to my voicemail

Answered and it never actually answered - the call hung up almost immediately.  Seems someone is testing a random caller program.  Was the second one this morning, both were local numbers.

I screen calls. This number just rang my phone today. It showed as Rockwall, TX. I did not answer, and no message was left
