Troubleshooting



Image ModifiedNot seeing any SIP response code data? 

  1. Check SIP Tracing is enabled within the configuration of your Session Manager or Session Border Controller.
    1. Further help configuring SIP Tracer is available here.
    2. Note for v8.0 of Avaya SBCs there is a known issue enabling the SIP Tracer, where clicking the checkbox does not save.
  2. Ensure any firewalls or network security allows the SIP Traces to route to the VSM Collector IP address on UDP port 514.     
  3. Still having issues? Contact your Business Partner or Virsae support.
