I have no idea who they are. I sm with Kaiser and they know to call my office phone. I cannot use my cell phone at my office. I understand this is an invalid number. I have been receiving calls from invalid and non-existing numbers for months. How can an invalid or non-existing number be used to call me?
I have checked another number that is reported as RESTRICTED and is supposedly located in Texas but apparently being used by different csllers--some of which are out-of-the-country. There have bern numerous complaints. I have found missed calls from them at two and three in the morning. Most times when it calls my phone does not ring. The one time it rang and I attempted to answer it the phone krpt right on ringing. I have been fortunate; I have not spoken to anyone from that line! Complainers have mentioned extortion attempts and vicious threats. Many of these peopleare on no-call lists so this number may be bring used to get around the lists. One complainer said the caller threatened to cut his head off and stick it down his throat. If that is not a terrorist threat what is?
Kaiser masks their outgoing phone call numbers so as to not get robocalled or spammed. They also cannot leave medical messages on your phone without express permission thus no message. Blame HIPPA, not Kaiser. OK?
