Voice over IP

Is your VoIP service VIP conform?

With the Voice over IP testing capabilities of SITE, it is possible to perform real time end-to-end active VoIP-testing to determine the customer’s experience of the service.

Testing Voice Quality

Although Voice Quality is vitally important for any type of network that routes voice traffic, the shift from dedicated circuits to the efficiency of IP based traffic, brings its own problems with regard to the end customer’s perception of performance. The possibilities for Delay, Jitter and Packet Loss over an IP based infrastructure, means the network operator must constantly check the Voice Quality metrics to ensure that problems are detected before they cause major disturbances and dissatisfac-tion to the customers. As well as ensuring that end-to-end connections can be established, maintained in a speech state for the required test period and success-fully cleared down, the quality of real sound samples needs to be checked throughout the “speech” phase of the connection.

This is why SITE supports voice quality testing according to the PESQ algorithm recommended in the ITU-T P.862 standard.
