Load Generation

The following parameters are used for load generation. These parameters do not need to be modified if you want to make User-Agent-to-User-Agent calls:

LoadGen_On              bool            False
RunMode                 string          Calling
StartTime               int             5000
NumKickStarts           int             1
CallUrl                 string          sip:7399@mendel
NumEndpoints            int             1
CallDuration            int             1000
CallDelay               int             1000
CallRestartTimer        int             17000
AnswerRestartTimer      int             12000
AnswerDelay             int             100
MonitorMsgOn            bool            False
MonitorMsgInterval      int             10
DialNumber              string          6000
NumOfCalls              int             -1
CJTime                  bool            False
RtpGenOn                bool            False
