Why do finnish people say 'Morris Morris' (or Moi Moi) when answering the phone?

moi = hi
moi moi = bye
?

I know what it means I want to know how it came about. It never seems to be used in person, (Hei and Huomenta seem to be used there)

While working with Alexander Graham Bell to discover words of greeting, Edison is credited as creating the word "Hello" as a telephone greeting in 1877.[43][44][45] Bell, however, preferred "Ahoy-hoy" as a greeting.[46] (Hello is a variant on the old word hallo.)

Etymology is interesting.

Probably interesting: article about the etymology of the Frisian MoinMoin:

My favourite is mushi mushi.

mr burns says "ahoy-hoy" when he answers the phone in the simpsons.

i was thinking of "moshi moshi" as well, is finnish related to japanese at all?
