The cumulative sum of all round trip time measurements in seconds since the beginning of the session.

Description

Real number; in seconds

Represents the cumulative sum of all round trip time measurements in seconds since the beginning of the session. The individual round trip time is calculated based on the RTCP timestamps in the RTCP Receiver Report (RR) RFC3611, hence requires a DLSR value other than 0.

The average round trip time can be computed from totalRoundTripTime by dividing it by roundTripTimeMeasurements.
