It won't work as the telephone cannot transmit that loud and sudden a sound. Your hearing will pay the price-the caller (human or computer) could care less. It's a myth.
I received calls from: Medical Svc 520-265-8938, Frist Medical 908-469-0995, Starr Enterprise 701-552-7499, Health Solutions 775-800-7054, AAA Medical 949-484-8683, Vision Solutions 734-418-9006, Medical Solutions 786-345-1584, Contacto Medica 864-412-3327, SR Medical Sol 913-725-0453. A total of 14 calls in the last 24 hours.
As soon as I block a number, they start calling from a different number.
They call my cell every 10 minutes. No one there. When I call back from a land line the number is unavailable.
I put my number on do not call list but somehow they get around it.
One time I answered and it started to ring as if I was the one calling them.
Scary. I thought it might be a reverse call out of the country or something so I hung up immediately.
This has to STOP!!
I received two calls from the same "conragulations, you've won..." number within a matter of 10 minutes. If I wasn't working, I would take the time to mess with them. Oh well.
