Edna Poplin (the Poplin Family of South Carolina -- we have an older Folkways LP of their music), wrote a song with that title that starts:

Sit at home, the telephone
Don't ring any more,
Why should I cry over you?
Low and lonely, sad and blue,
Sittin' here, baby, just thinkin' of you,
Why should I cry over you?

That's pretty obscure, and probably not the one you're looking for, but...what the heck...no harm in asking.
