ACS Populates EDR RELC From CIR When No Release Cause Was Requested Or Provided

On Oracle Communications Convergent Charging Controller(OC3C), 6.0.1 version, it is observed that Advanced Control Services(ACS) populates Event Detail Record(EDR) RELC from the Call Information Report(CIR) when no release cause is requested or provided.
Consider a scenario when ACS is configured to use the CIR but not use the Release Cause, i.e, when SendCIR = 1 and AskCirReleaseCause = 0, the RELC value in the EDR is overwritten with 0.
In other words, it appears that the Telephony Release Cause is overwritten by the Release Cause from the CIR, even when a CIR Release Cause is not requested or supplied. This means that our EDRs will always have RELC=0.
It is expected that RELC contain the INAP/CAMEL call release cause value. ie, it will be like below:
- If SendCIR = 0, RELC = regular INAP/CAMEL Release Cause.
- If SendCIR = 1,
a. AskCirReleaseCause = 0, then RELC = regular INAP/CAMEL Release Cause.
b. AskCirReleaseCause = 1 and CIR provides the release cause, then RELC = as provided in CIR.
c. AskCirReleaseCause = 1 and CIR does not provide the release cause, then RELC = regular INAP/CAMEL Release Cause.
The issue can be reproduced at will with the following steps:
1. Enable SendCIR in acs.conf.
2. Enable any or all of the AskCIR* parameters except 'AskCirReleaseCause'.
3. Run a charged call where either party disconnects after talk time is used.
