you need to have the call ..."whoever" set up though, so you'll need someone who is willing to be "jane" in your scenario, and understand that "jane" might not be in/available when you call. IMO in your situation, it may be better (if you have a landline) to get a care alarm of some sort. That way, it is ALWAYS answered and if your nominated contacts do not answer, professional call handlers can talk to you, and send appropriate help. Even for a care alarm, you need someone to be "jane"
