During a search of the defendant's apartment based on a warrant for narcotics, the phone rang. An officer answered the phone, and the unidentified caller asked, "Have the apples arrived there?" The trial court allowed the officer to testify about the statement and admitted additional evidence explaining that narcotics traffickers often employ code words to discuss unlawful narcotics on the telephone. Should the trail court have held that the police officer's testimony about the content of the phone call constituted inadmissible hearsay?
