Abstract
The present invention enables testing of a VoIP network using various instrumented test streams. The testing can determine the quality of the transmission network before an internet VoIP service is put into production. The testing also enables regular diagnostic audits of a VoIP network to maintain the quality of the VoIP network. The testing enable measurement of, for example jitter, packet loss and delay and allow characteristics of the VoIP network to be obtained. In addition, the present invention can to determine the capacity and utilization of a VoIP transport network. Based on the measurements and characteristics of the VoIP network the present invention can control routing of a call on the VoIP network or can prevent a call from being made. The present invention also enables dynamic switching of CODECS during a session to enhance the performance of the VoIP network.
