Secure VoIP Performance Measurement

However, there would be some trade-off in term of voice quality and bandwidth requirement. Other codec types would have some form of data compression in them. Hence, less bandwidth is required to sustain the succession of audio signals in the VoIP service. However, the voice quality would decrease due to the data compression. The payload size for the G.711 codec with 64kbps bandwidth and 20ms sample period is 160 bytes.
