Communication method for voice calls

摘要

A communication method capable of providing voice communication between a first apparatus and a second apparatus includes establishing a voice call between the first apparatus and second apparatus to provide voice communication between the first and second apparatus. An identifier is generated to identify the voice call. During a first portion of the call, the voice communication is provided using a packet switched technique that includes conveying packets of voice data between the first and second apparatus via a communication connection. The communication connection is labelled with the identifier. During a second portion of the call, the voice communication is provided using a circuit switched technique that includes allocating a defined route to convey voice data between the first and second apparatus. Also during the second portion of the call, the identifier is used to manage said call.
