fax number belongs to Mobilex - they were faxing medical test reports to me that weren't even for me - had my fax # by mistake - every freaking 5 minutes....3 calls to my AT&T repair, 2 calls to the Dr's office and one call to 1-800-940-0389 in Clearwater, FL.......AT&T said to dial in 1234567 when you hear the fax trying to make contact and it will send an error message to their computer?!?!? Don't know yet if that worked or not - try it! 800# said to unplug my fax to try to break the signal?!?? I'm sitting here waiting for my phone to ring again!
