Table 5-9: Call Counters Description (continues on pages 73 to 74)
Counter Description
Number of Established
Calls
This counter 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 bigger then 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.
Number of Failed Calls
due to a Busy Line
This counter 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 Failed Calls
due to No Answer
This counter indicates the number of calls that weren’t answered. It is incremented
as a result of one of the following release reasons:
GWAPP_NO_USER_RESPONDING (18)
GWAPP_NO_ANSWER_FROM_USER_ALERTED (19)
And (when the call duration is zero) as a result of the following:
GWAPP_NORMAL_CALL_CLEAR (16)
RELEASE_BECAUSE_NORMAL_CALL_DROP (internal)
Number of Failed Calls
due to No Route
This counter 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
This counter indicates the number of calls that failed due to mismatched gateway
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 Other Failures This counter is incremented as a result of calls that fail due to reasons not covered
by the other counters.
