The RTP/RTCP stack is widely used as the data transport protocol in real-time network services such as Voice over Internet Protocol (VoIP) applications. The use of the packet switched network for voice increases bandwidth utilization compared with the traditional connection-oriented approach and can lead to lower call costs. The nature of packet   switched networks can cause unpredictable and variable delays to speech packets, often resulting in poor unintelligible speech at the receiving end. The effect due to these delay variations or jitter can be minimized by using a Jitter Buffer, which imposes a certain delay to each packet before playing back the packet stream at a constant rate. The library provides an integrated jitter buffer to counter the same along with RTP/RTCP module.
