For some time now, I have almost stopped answering the phone. I do not just mean unknown numbers: with few exceptions, I also let calls from people I know ring out, then calmly check why they were trying to reach me.
This habit has saved me a considerable amount of mental load. Yet it prompts very different reactions. For some people, not picking up is almost an insult. For others, it has become obvious that a call should be preceded by a message or reserved for a genuine emergency. That gap is worth examining, because it is not just about the phone: it concerns how we protect our attention and organize our communication.
A call gives someone else’s priority precedence
When someone calls you, they need you for some reason: to get information, make a decision, solve a problem, or simply talk. They choose a channel that requires you to react at the exact moment their need arises.
The phone does not let you know why someone is calling before you answer. It therefore places every request at the same apparent level: a quick question from a colleague, a sales call, important news from someone close to you, or someone looking for a supplier’s contact details all trigger exactly the same ringtone.
Picking up means accepting that this request will interrupt whatever you were doing. Perhaps you were focused on difficult work, driving, making dinner, or simply taking a moment for yourself. In every case, the caller decides when to make the request, while you have to judge its importance without knowing what it is about.
I am putting this somewhat cynically, but the problem is real: someone else decides for you what deserves your attention right now. And if we consider productivity to be the ability to use your energy intelligently, that interruption comes at a cost. It is not just the few minutes spent talking; you also have to regain your train of thought afterward.
Calls that justify an interruption
This obviously does not mean that every call is unjustified. Two situations seem to me to fully justify answering.
The first is when the caller knows what you are doing and can reasonably assume that they may contact you. This applies to a scheduled call, an expected conversation as part of a project, or someone close to you who knows you are available. In fact, it is no longer really an interruption when both people have agreed on it.
The second is a genuine emergency. If your partner is locked outside your home because they left their keys at work, it would be absurd to blame them for not sending an email. Health, safety, an unexpected family situation, or an incident requiring a quick decision are precisely the cases in which the phone remains irreplaceable.
The problem is that most everyday calls fall into neither category. They are neither agreed upon nor urgent. The caller simply wants an answer and uses the method that seems most direct, without necessarily considering what the other person was doing.
Default to asynchronous communication
In most cases, a written message is enough. An email, text, or WhatsApp message lets the sender explain the subject and clarify the request. I can then read it, understand its importance, and deal with it at the appropriate time. If a spoken conversation is genuinely necessary, we can then schedule a time or call each other when we are both available.
This is the principle of asynchronous communication: the sender and recipient do not need to be available at the same time. This way of working has become much more common in tech, particularly through tickets and project management tools, but it is just as relevant to everyday communication.
Asynchronous does not mean replying slowly, let alone ignoring people. I can see a message and respond immediately if I am available. The difference is that I have the context first. I can decide whether the request deserves a reply within a minute, within an hour, or later that day.
A written message also benefits the person sending it. It forces them to articulate what they need, leaves a record, and sometimes avoids an entire conversation. An address, a date, or a supplier’s name is better shared in writing than in the middle of a conversation that will then have to be transcribed or remembered.
More broadly, this approach ties in with inbox management. A message becomes a visible request that I can sort and turn into a task if necessary. A call, by contrast, requires me to deal with the request when it arrives, even if the circumstances are not suitable.
Staying reachable by the right people
Most smartphones now let you define priority contacts or exceptions to silent and “Do Not Disturb” modes. Properly configured and kept up to date, this feature offers a simple compromise: block ordinary calls while remaining reachable by the few people who might contact you in a genuine emergency.
This list should remain short and reflect your life. It might include your partner, your children, certain relatives, or, depending on your responsibilities, one particular person in your professional environment. The aim is not to recreate a complete directory of people allowed to interrupt you, but to guarantee a reliable emergency channel.
You also need to explain the rule. If the people close to me know that I generally do not answer but that they can call again immediately in an emergency, the second call becomes a clear signal. Others may prefer to use a specific word in a text message. The mechanism matters less than the convention: everyone needs to know how to reach you when the situation genuinely requires it.
The phone as a symptom of “single-threaded” organization
People who systematically favor the phone sometimes manage their requests in a very sequential way. They think of something, call the person concerned, get an answer, then move on to the next item. If they cannot complete that action immediately, they worry they will forget it.
Borrowing a term from computing, I call this “single-threaded” organization: only one thread of work progresses at a time, and every obstacle must be removed before it can continue. A call then becomes a way to keep that thread moving, but it transfers the interruption to someone else.
I can understand this reflex without accepting its consequences. Everyone should have a system reliable enough to record a request, wait for an answer, and return to the subject later. Someone who organizes their work in writing can move on to something else in the meantime; they do not need to immediately enlist the other person just to avoid losing track.
In some cases, the phone is also used to assert power. A written request can be examined, rephrased, and prioritized. A call creates more pressure: you have to answer in real time, without always having the necessary information or time to think. Of course, not everyone who calls is disorganized or domineering, but the channel is particularly well suited to these behaviors.
Not picking up restores a simple boundary. It is not about refusing the request; it is about asking for enough context to choose how and when to handle it.
The case of unknown numbers
The question is even simpler with unknown numbers. Sales calls and scam attempts have become common enough that, in my view, a ringing phone with no clear identity no longer deserves an automatic answer.
Someone with a legitimate reason to reach me can send a message, leave a clear request, or contact me through another channel. I do not assume that every unknown number is malicious; I simply believe it is up to the caller to provide a minimum of context before I give them my attention.
This rule also has the advantage of being easy to apply. There is no need to assess an area code, the time of day, or the plausibility of a call within a few seconds. I let it ring, then check the available information.
Voicemail does not always solve the problem
In principle, voicemail fits the logic of asynchronous communication perfectly. Someone explains what they want, I listen to the message when I am available, and I decide what to do next. The automatic transcription offered by some phones makes this even more convenient, since you can scan the content without listening to the entire recording.
The problem is messages that say nothing more than, “Can you call me back?” They are almost worse than a missed call. The person passes the ball back to me without explaining the subject, its importance, or how long the conversation will take. I now have to remember to call back, still with just as little information to choose the right time.
A useful voicemail should provide the context missing from the call: “I’m calling about the quote. I have a question about the second line; please call me back before tomorrow if possible.” I then know why the person is contacting me, what I may need to prepare, and when I need to respond.
The rule I follow
Personally, I have chosen a more radical solution: my voicemail greeting says that I do not listen to voicemail messages. It asks callers to send the subject of their call by text, WhatsApp, or email. The rule is explicit, and nobody needs to wait for a reply that will never come.
I have received several negative comments about this. Some people seem to consider the ability to leave a voicemail an obligatory part of telephone etiquette. In my experience, these are often people from organizations that are still very attached to the phone, such as certain property management companies or public agencies.
In the medium term, this minor friction seems acceptable to me. It affects a small minority of people and usually disappears once they know how I operate. Most importantly, it prevents every call from creating a new, opaque obligation in a channel I do not want to monitor.
I am not claiming that everyone can stop answering the phone. Some jobs, family responsibilities, and periods of life require immediate availability. But that availability should correspond to a real, explicit need, not a convention that has never been questioned.
The real question, then, is not “Should I always answer?” but “Who should be able to interrupt me, for what reasons, and by what means?” Once those questions have clear answers, the phone becomes what it should be again: a highly effective tool for conversations and emergencies, rather than a priority imposed by default.
