Seems to be related to ringout calls missing the call from name / call from number.
Please let me know if you need examples, and I will upload some.
Our app name is: RC_Log_Exporter
May be the call log needs to be fully exported - are you using the right API/option for the export? I saw a post on how to do that in this link - https://developers.ringcentral.com/guide/voice/call-log/reading-call-log
