Who does the programming of telephone boards (landlines)?

Question

Telephony

I have old grandparents unable to dial my home number. Is it possible to program the telephone card to 1 specific number? So that when you press any button, 1 specific number is automatically dialed? Are there people who do this? Is it just amateurs or is it a "profession"?

Answer 1

Most IP phones have dialplan type settings or dialing rules.
Yes, up to the fact that when you pick up the handset, a call will go.
You can find out more on Google, on a specific phone number.

Answer 2

I have old grandparents unable to dial my home number.

Why don't you use special devices like "panic button"?

Are there people who do this?

Yes. As well as companies, portals, etc.
