I have asked them. They are basically not prepared to share any
information on details.
It is somehow a service they provide, but how it is implemented is unknown.

I'm sure they did not even understand what I was asking. :-/
eCall seems to be a more open system, but still no real informations to
find. And it as a slightly different focus too.

That would be a great thing to have indeed. This needs to be included in
the (FSO) dialer/contacts framework. Including the other special numbers
the sim has, like ones own.
Imagination is more important than knowledge.
