Viewing Tel-to-IP and IP-to-Tel Call Counters

You can view statistical information on IP-to-Tel and Tel-to-IP calls in the Web interface's Calls Count page. The information is updated according to the release reason that is received after a call is terminated (during the same time as the end-of-call CDR message is sent). The release reason can be viewed in the 'Termination Reason' field in the CDR message.

You can reset the statistical data displayed on the page (i.e., refresh the display), by clicking the Reset Counters button located below the table.

➢ To view IP-to-Tel and Tel-to-IP call counters:
■ Open the Calls Count page (Monitor menu > Monitor tab > VoIP Status folder > Calls Count); the figure below shows the IP-to-Tel Calls Count page.

The fields in this page are described in the following table:

IP-to-Tel Calls Count and Tel-to-IP Calls Count Description

Counter

Description

Number of Attempted Calls

Indicates the number of attempted calls. It is composed of established and failed calls. The number of established calls is represented by the 'Number of Established Calls' counter. The number of failed calls is represented by the failed-call counters. Only one of the established / failed call counters is incremented every time.

Number of Established Calls

Indicates the number of established calls. It is incremented as a result of one of the following release reasons if the duration of the call is greater than zero:

■ GWAPP_REASON_NOT_RELEVANT (0)
■ GWAPP_NORMAL_CALL_CLEAR (16)
■ GWAPP_NORMAL_UNSPECIFIED (31)

And the internal reasons:

■ RELEASE_BECAUSE_UNKNOWN_REASON
■ RELEASE_BECAUSE_REMOTE_CANCEL_CALL
■ RELEASE_BECAUSE_MANUAL_DISC
■ RELEASE_BECAUSE_SILENCE_DISC
■ RELEASE_BECAUSE_DISCONNECT_CODE

Note: When the duration of the call is zero, the release reason GWAPP_NORMAL_CALL_CLEAR increments the 'Number of Failed Calls due to No Answer' counter. The rest of the release reasons increment the 'Number of Failed Calls due to Other Failures' counter.

Percentage of Successful Calls (ASR)

The percentage of established calls from attempted calls, known as Answer Success Ratio (ASR).

Number of Calls Terminated due to a Busy Line

Indicates the number of calls that failed as a result of a busy line. It is incremented as a result of the following release reason: GWAPP_USER_BUSY (17)

Number of Calls Terminated due to No Answer

Indicates the number of calls that weren't answered. It's incremented as a result of one of the following release reasons:

■ GWAPP_NO_USER_RESPONDING (18)
■ GWAPP_NO_ANSWER_FROM_USER_ALERTED (19)
■ GWAPP_NORMAL_CALL_CLEAR (16) (when the call duration is zero)

Number of Calls Terminated due to Forward

Indicates the number of calls that were terminated due to a call forward. The counter is incremented as a result of the following release reason: RELEASE_BECAUSE_FORWARD

Number of Failed Calls due to No Route

Indicates the number of calls whose destinations weren't found. It is incremented as a result of one of the following release reasons:

■ GWAPP_UNASSIGNED_NUMBER (1)
■ GWAPP_NO_ROUTE_TO_DESTINATION (3)

Number of Failed Calls due to No Matched Capabilities

Indicates the number of calls that failed due to mismatched device capabilities. It is incremented as a result of an internal identification of capability mismatch. This mismatch is reflected to CDR via the value of the parameter DefaultReleaseReason (default is GWAPP_NO_ROUTE_TO_DESTINATION (3)) or by the GWAPP_SERVICE_NOT_IMPLEMENTED_UNSPECIFIED (79) reason.

Number of Failed Calls due to No Resources

Indicates the number of calls that failed due to unavailable resources or a device lock. The counter is incremented as a result of one of the following release reasons:

■ GWAPP_RESOURCE_UNAVAILABLE_UNSPECIFIED
■ RELEASE_BECAUSE_GW_LOCKED

Number of Failed Calls due to Other Failures

This counter is incremented as a result of calls that failed due to reasons not covered by the other counters.

Average Call Duration (ACD)

The average call duration (ACD) in seconds of established calls. The ACD value is refreshed every 15 minutes and therefore, this value reflects the average duration of all established calls made within a 15 minute period.

Attempted Fax Calls Counter

Indicates the number of attempted fax calls.

Successful Fax Calls Counter

Indicates the number of successful fax calls.
