I would like to know what are the cause values that pegs for the below performance counters in Siemens
How does the switch able to determine to peg a call under CCS_UNANSWER. What are C7 signalling message that it looks at to peg for this counter?
This counter registers the number of calls that, after being successfully connected
through switching network, are rejected because either the called device did not answer
or the calling party went on-hook during ringing.
Trigger at LTG error
The counter is triggered when the LTG reports the following RCF.
RCF#016 : RF_NORMAL_CALL_CLEARING
RCF#018 : RF_NO_USER_RESPONDING
RCF#019 : RF_NO_ANSWER_FROM_USER
RCF#020 : RF_SUBSCRIBER_ABSENT
RCF#028 : RF_INVALID_NUMBER_FORMAT
