When a CallGenerator is used in an audio quality measurement configuration, the CallGenerator computes the uplink AQM data and outputs it in XML files. This uplink data needs to be inserted in each logfile (*.trp) recorded with TEMS Investigation. To perform the data merge, you need to export the TEMS Investigation logfile with Format set to PESQ merge. The output is a new logfile (still in *.trp format) that includes both uplink and downlink AQM data.
