This number is to a company called Prison Call Solutions (PCS). They help inmates and their families have less expensive phone charges by deposing funds into an account that serves as a local calling card, to avoid long distance charges. this company serves all US jail facilities, hence all the different caller ID locations.
Keep getting unwanted automated calls from 972-280-7286, shows up PCS.
I am going to report this number to the attorney general's office. Due to the no call list.
