Should I let her calls go to voicemail?

In short

Voicemail may not give her the reassurance she needs, so she may call again.
The aim is not fewer calls. It is every call answered kindly, and not always by you.
Set hours, say them out loud, and put the same short note and a clock beside her phone.
In the hours you cannot answer, a familiar voice can: a sibling, a friend, or your own recorded voice.

What happens when a call goes unanswered

She calls because a worry has surfaced: where you are, whether you are coming, whether something has been forgotten. When the call rings out, the worry has nowhere to go. She may leave a message, but she does not remember leaving it, so she calls again. By the time you step out of your meeting there is a row of missed calls and a voicemail that says only your name.

Seeing several missed calls can be upsetting. Take a moment to check what she needs, then think about who could share the calls with you. You deserve support too.

Why voicemail may not help

Dementia can make it harder to remember leaving a message or understand when a reply will come. Your greeting may reassure her briefly, but the worry may return before you can call back.

Notice how she responds. If unanswered calls leave her more unsettled, try a regular call time, a clear reminder, or another person she can reach.

Boundaries without blocking

You are allowed to have hours. What helps is making them something she can see and hear, rather than a silence she has to interpret.

Set hours and say them out loud. "I answer from six to nine, Mum," said the same way each time, is easier for her to hold than a schedule she cannot see.
The same short reassurance each time. Not new information. The same three sentences, in the same order, in the same tone.
A note and a clock by her phone. A card in large print: "I am at work until 6. I will call at 6." A clock with a big face beside it.
Siblings taking turns. One person carries one evening. Her calls go to whoever is on, and the others rest.
A familiar voice answering in the hours you cannot. A voice she knows, giving the same reassurance, is kinder than a ring that goes nowhere.

What to say when you do pick up

Keep it short, warm and the same every time. You are not answering a question; you are settling a feeling.

"Hi Mum, it's me. I'm here."
"You're at home, and you're safe."
"I'm at work. I'll call you at six."
"I love you. Talk soon."

No correcting, no "you already asked," and only promise what you will do. If she asks the same thing again, say the same thing again.

Where Voice Companion fits

In the hours you have chosen not to answer, Voice Companion answers her call in your own recorded voice, from a local number saved in her phone under your name. It follows her lead, never corrects her, never says she already asked, and winds down warmly after about five minutes. Outside the hours you set, her call rings your own phone as it always has. It does not make the calls stop. It makes sure each one is answered kindly when you cannot. How it works.

Questions people ask about this

Is it okay not to answer sometimes?

Yes. Missing a call does not mean you have let her down. A shared plan for regular calls, reassurance and access to help can make your time away easier for both of you.

Should I block her number while I am at work?

Before blocking calls, make a plan for how she can reach support when you are unavailable. Talk with family or her care team about an arrangement that meets her needs and gives you time to rest.

Will she remember that I did not pick up?

Usually not the fact of it, but often the feeling. The memory of the call fades; the unease can linger into the evening. That is why the same short reassurance, in a voice she knows, does more than a long explanation later.
