Article is behind one of those annoying paywalls so I couldn't read it. Phone 'etiquette' isn't what it used to be 20-30 years ago. There are now SO many scams/sales pitch calls that I no longer answer my phone if I don't recognize the number. Real/legit business people will leave a message such as the doctor/dentist or someone doing some sort of home repair/landscaping. IF the only calls I got were always legit, then I think how people respond would be different. I don't see the need to text someone prior to calling them. If I want to ask a question or confirm something, a brief phone call isn't the end of the world. They might not be home, doing yard work or running the sweeper so they can't hear the phone. Even if I call someone's cell phone there are number of reasons they may not answer. In public, there is often so much background noise or loud music playing in a store, you may not hear your phone. I don't expect anyone to always instantly answer the phone and don't have any problem leaving a message for when it is convenient for them to return my call. With caller ID, you can also tell that someone has called even if they don't leave a message. Scam callers NEVER leave a message since they know you won't be calling them back.
Some idiot calling to scam me saying I owe money to some doctor/hospital I have never been, owe back taxes or the police are going to arrest me............I have NO interest in hearing from. Many of these callers talk really fast with such a heavy foreign accent I can hardly understand them. The fast talking sales pitch types think you are obliged to listen longer if they never stop to take a breath.........nope.........I just hang up.........LOL. One of the newer ones are the callers who start by saying this call is being recorded..........I just hang up. What possible reason would a legit business caller need to do that? None that I can think of. It is a bit like starting the call by saying they are running some sort of scam !!! All of those bogus calls are now SO frequent, is the main reason most aren't answering their home phone. Robo calls didn't used to exist where they now automatically calling every number in a certain exchange trying to sell any number of things I don't want/need.
My home phone allows me to create a list of numbers to 'ignore'. Scammers who keep calling me daily, go on that 'ignore' list and can no longer get through which is fine by me. Texting is fine for yes/no type questions, but if I need to discuss something, I prefer to use the phone and talk live to that person. It is far too clumsy/time-consuming to try to have an actual 'conversation' via text.
