Pullen used aluminum brackets in her business. On the telephone listed as hers in the telephone book, Pullen received a call in which the caller said, "This is John Denison of Denison Hardware Company. We have a special on aluminum brackets this week at 30 percent off." Pullen ordered brackets from the caller. When the brackets were never delivered, Pullen sued Denison for breach of contract. At trial, Denison, who denies having made the telephone call, objects to Pullen's testimony concerning it. When asked, Pullen testifies that, aside from the telephone call, she had never heard Denison speak until she met him in the judge's chambers before the trial and that, in her opinion, the voice on the telephone was Denison's. The strongest argument for admission of Pullen's testimony concerning the telephone call is that
the call related to business reasonably transacted over the telephone. the call was received at a number assigned to Pullen by the telephone company. after hearing Denison speak in chambers, Pullen recognized Denison's voice as that of the person on the telephone.  self-identification is sufficient authentication of a telephone call
