In a trial between Jones and Smith, an issue arose about Smith's ownership of a horse that had caused damage to Jones's crops.Jones offered to testify that he looked up Smith's telephone number in the directory, that he called that number, and that a voice answered, "This is Smith speaking." At this, Jones asked, "Was that your horse that tramped across my cornfield this afternoon?" The voice replied, "Yes." The judge should rule the testimony
admissible, because the answering speaker's identification of himself, together with the usual accuracy of the telephone directory and transmission system, furnishes sufficient authentication.  admissible, because judicial notice may be taken of the accuracy of telephone directories.  inadmissible unless Jones can further testify that he was familiar with Smith's voice and that it was in fact Smith to whom he spoke. inadmissible unless Smith has first been asked whether or not the conversation took place and has been given the opportunity to admit, deny, or explain.
