Yeah this number calls my wife every so often. Perhaps they get money every time you call them back. Like a fundraising deal. When I call it an automative service answers and says something like "This call may be recorded for quality or training purposes. Please stay on the line for a representative." Then it sounds like someone answers, there is a lot of noise in the background like a call center then they hangup about seconds later or else it is disconnected.
Has called all of our household cell phones numerous times, even minor children. Robo calling? Asks for "Tony". Says from Diabetic Connect about a meter.
