Hi, I've got an iPhone 5 and only use FaceTime on my home wifi network but have an issue with the sound cutting out all too frequently. The call appears to be normal for the first five minutes or so and then the sound drops out on my side only (the other party can still hear me fine). A hangup and redial sorts it out but then it reoccurs after another two minutes or so. Google hasn't been too much help and Apple haven't responded to a fault I raised with them about a week ago. Thought I'd see if anyone else here has had this type of issue and / or knows a solution. Merry Christmas.
