Abstract: Provided is a method and apparatus for objectively and non-intrusively measuring voice quality on live calls without disrupting the call session or the network. A communication system includes plural communities each including a switch that controls access to a packet-based data network for call sessions. Each of the communities is coupled to the data network by respective packet-based trunks. Quality of service (QoS) monitoring devices are coupled to the respective packet-based trunks to monitor quality levels of routes between any two given communities. Each QoS monitoring device receives packets containing streaming data (which may be actual packets or test packets). From the received packets, the QoS monitoring device can derive QoS parameters, particularly for audio and speech signals on live calls without disrupting the call session.

Abstract: A method and apparatus for triggering data-path conversion utilizing PCM bit robbing signalling. The method and apparatus permits the pass-through of compressed voice packets over a PCM stream between dissimilar interconnected networks or dissimilar payload specifications in the interconnected networks, and also provides the capability to convert the packets to a different payload specification between the networks. Once a voice path is established between the two networks, the incoming PCM data stream is monitored for a voice synchronization pattern which appears periodically in a predetermined bit position in the PCM samples. Upon detection of a matching voice synchronization pattern, a pass-through mode for the voice data between the networks is initiated. A data or payload conversion operation may also be initiated on detection of the matching voice synchronization pattern.
