- Abstract:
- The voice quality in Internet Protocol (IP) telephony is significantly influenced by various factors, including delay, delay variation, bandwidth congestion and the distribution of packet loss. Hence, the performance of IP telephony systems is highly dependent on understanding the contribution of these factors to the voice quality. This paper deals about a method for classifying Voice over IP (VoIP) network impairments analyzing the signal power during a phone call. In particular, three main impairments have been considered: packet loss, jitter and bandwidth congestion. From the voice signal some figures of merit have been extracted and used to identify the impairments affecting the communication.
