An external capability for measuring roundtrip latency in a conferencing system is provided. The external capability for measuring roundtrip latency in a communication system may include functions of generating a content event, detecting the content event in a received content stream including the content event, determine a first time associated with generation of the content event and a second time associated with detection of the content event, and computing a roundtrip latency based on a difference between the second time and the first time. The content event may be a visual event or an aural event. These functions may be implemented using one or more modules or elements. A computing device may be used to generate and detect the content event and to compute the roundtrip latency. Various other arrangements of modules or elements may be used to provide the functions.
