Because my sick elderly dad needs to be in constant contact with doctors and care providers on a nearly daily basis. We can't afford to miss a phone call that may cause a delay to getting help, medication, or a procedure. Most of these offices don't use their actual numbers on outgoing calls, so it's hard to know what is a spam call or a call from another different provider or another provider's office. Unfortunately, this means I have to answer the phone for every call that comes in. These junk calls add so much stress and interruption to my life. There are at least 8-10 junk calls per day. So I'm interrupted from my full time job, or the job of caring for my father at least once an hour every single day.
