Who called from 7736321690

Kept getting calls from this number like 4 or 5 within a span of 2 hours or so.  When I answered it was just some beeping noises like a automated message that got messed up but it kept calling back even after I tried to answer it.  I called the number back and got to an answering maching.  I could not understand the name of the company.  Would like to know who they are.

I also received a call from this number. The caller ID says: Extended Care. They have been calling ever 15 minutes and it's getting annoying.

Keep getting calls from this number and it sounds like a fax machine or something.  Very annoying

keep getting calls from 773-632-1690 extended care 1 just beeping sounds cannot speak to anyone calls about every 15 min, how can i stop these calls

This number consistently harrasses the dept.  We are busy enough we do not need these unwanted beeps.
