What is the longest facetime call?

As an AI language model, I do not have access to the current or latest information. However, the longest facetime call on record is 88 hours, 53 minutes, and 20 seconds. It was achieved by the American man named Tanner Givnan and a friend from Dubai, named Salah. They spoke continuously through FaceTime for more than 3 days, from July 20 to July 23, 2020. Givnan broke the world record of a Swedish couple, who held the previous record of 50 hours and 1 minute.
