This article applies to Aruba Mobility Controllers running ArubaOS version and higher.


ArubaOS enables you to debug voice issues more efficiently and quickly by providing detailed information about the voice calls, voice client status, and Call Detail Records (CDR).

You can obtain the advanced troubleshooting information such as time of failure of the call, status of the client during the call failure, signal strength of the call, AP handoff information, and signaling message issues.

ArubaOS allows you to view the voice CDRs for the completed calls. Additionally, it enables you to view more details such as AP handoff information and AP station reports for a specific terminated call based on the CDR Id.

The AP handoff information includes the AP events such as association request, re- association request, and de-authentication request with timestamps. The AP station report includes the AP MAC address, association time, average RSSI value, and retries count.


NOTE:  If Syslog server is configured, ArubaOS pushes the generated CDRs to the syslog server to retain the older CDR data for a later analysis. The CDR data pushed to the syslog server do not contain the details of the AP stats and AP events.

You can use the WebUI or CLI to view the troubleshooting information on a voice call based on the CDR Id.

In the WebUI

1. Navigate to the Monitoring > Voice > Call Detail Report page. This page displays the CDRs of the completed calls.

2. Click the CDR Id of a call to view the AP station reports, and the AP handoff information of the call.

In the CLI:

To view the details of a completed call based on the CDR Id:
