Alexa Echo -Dot - Echo show - Phone calls


My Mum is struggling with the phone as getting old and poor eyesight if I got her an amazon echo, could I programme it to call my mobile, or would I have to get one too?

Anyone else got one would you recommend for the elderly and which one is best to get, I suppose if she got one with a screen, I could see if she is OK?

I am already going to get one of the emergency buttons around the neck in case of a fall, this is just to make things easier to call family.

Thanks for any help
