The Orig-Term Report connects call legs in order to show the statistics. 

A call leg is a logical connection between two router/gateways or between a router/gateway and an IP telephony device. Normally, a voice call comprises two call legs, one from the originating softswitch/gateway and one from the terminating softswitch/gateway. 

In this scenario, in order to connect legs in one call,  the Orig-Term Report method requires next conditions to be met: 

  • Conf-id is the same for call legs
  • The last 6 digits of DST Number EXT match
  • Session time permissible variation is 1 second (+/-)
  • Disconnect time permissible variation is 5 seconds (+/-)

  • No labels
