I told you last week that among the new functions of iOS 7 is also found FaceTimeAudio, a feature that allows us to make VoIP calls through the feature FaceTime. Apple Lossless Audio CODEC (ALAC), offers us this option in the idea of not having to make only video calls in the situation where we want to have a "phone" conversation with a certain person, especially if he is in another country and possibly roaming. Given the option to use FaceTimeAudio, some have wondered how much data traffic these calls could generate, and mobile operators in Australia also offers an answer.
Telstra estimates a 10 minute VOIP call on a mobile would use about 6 megabytes [MB] of data while the same video call would use about 300 MB. But another VOIP app called Viber estimates its app uses about 2.3 MB for a ten minute call. For Apple Facetime Audio is more about locking people into their services and using it to call customers on other iPhones. In the US it is substantially cheaper to make the data call. If you are an iPhone customer calling another iPhone customer it is cheaper, but if you are calling an Android customer you have to pay more.
According to mobile phone operator telstra, a 10-minute VoIP call could generate between 6 and 2.3 MB of data traffic, while a video call of the same duration could generate up to 300 MB of traffic. These values are estimates and depend on network congestion and its type, so you can imagine that a maximum of 6 MB of traffic could be consumed by an application during a call.
