This is an Irving, TX number, local for us. It is one of several numbers used by robo callers under the guise of the 972-253- area and prefix. The last four digits are randomly changed but the area and prefix remain. Our guess is that the genius behind this system wants us to think the calls are coming from friends and neighbors in our own city. Like all robo calls, a message is never left.
I get calls frequently from 972-253-3204, 972-254-3701, 972-253-4103, 972-253-5102, 972-253-4801, and 817-385-6854. If I answer, I hear a couple of clicks and then nothing. If I call back and it picks up, I hear nothing or I get a busy signal. Every day the same thing, but the number changes frequently. It's becoming a daily hassle to report these calls! What else can you do?
