I'm looking for some guidance and understanding of feasibility with an arduino or esp32.

I have a family member who is a fall risk. I am not happy with any of the "life alert" like products on the market which call a service which calls 911.

The Goal: 1 wearable device and multiple button devices which can be mounted near the floor. When a device is pressed it dials her neighbor's phone number, and preferably play some pre recorded message. The wearable device should be small and rechargeable or a long lasting small battery. The mounted devices will be stationary and can be larger, but should be innexpensive enough to have a lot of them and not rely on being near an outlet (rechargeable or easy to replace battery).

Ideas/Brainstorming so far: the mounted an wearble devices connect to one central control system which does the dialing. I think bluetooth would work well which is why I'm thinking of using esp32. I could also have them relay a message to the controller or send a broadcast message. The house has a landline, which they use, so I am curious if I could connect the controller to the physical landline phone? Or if I should use voip or google voice. I would probably plug the main controller into the outlet instead of battery power. I am not sure if the main controller is something that is feasible with just esp32/arduino or if it should be done with a raspberry pi.

Some main questions: is this feasible? What process makes sense for making a call (voip, landline, or something else)? is this an arduino or esp32 job? Is bluetooth the best way to connect the devices to the main controller? device and library suggestions

I have programming/technical experience just not a lot of arduino knowledge to properly understand the limitations. I would love any feedback and knowledge you can provide.

I am going to start working in a professor's lab which is outside of my department, lets call this professor A. To do research as a course, I need a professor from my department (professor B ) to sign off it. What is the name for professor B's role? I am not doing research under them. Is this a faculty advisor?

Also, what does the role of professor B typically look like in this situation? Would I be frequently checking in with professor B? I am not doing a thesis (I found the lab too late to allow for a thesis track). I am guessing professor B should be related to the work I plan on doing so I can go to them with questions. I need to reach out to professors asap and I want to be clear what the responsibilities of professor B are when I reach out to them.

Hopefully this was clear, it's all a bit confusing
