We are having issues exporting the CDR files to a Billing Application server from the Publisher call manager (version 7.1.5) with four servers in the cluster. We have configured the CDR Management Billing Application Server Parameters properly. We confirmed network/SFTP connectivity by backing up the CCM database (using DRF) to that Billing server and the same credentials, so we know the servers can talk to each other. However, we do not see any CDR files being copied over the SFTP root directory. All servers in the clustomer are set to "Enable CDR = Yes", and all services that should be running are active. The CDR load interval is set at 5 minutes.
Any ideas as to what we may have missed?
