Dear Sir,
I reproduce below clarifications from google forum on call log retention for information.
"Hi User
Welcome to the Google Phone app community forum.
Call log retention is determined by your phone manufacturer, and your carrier. It is not in any way affected by the Google Phone app. You can use any dialer you want, and they will all show you the same call history. Older calls, usually determined by the number of calls, and not by dates, are cycled out of the phone to save on storage.
You will need to contact your phone manufacturer, and/or your carrier if you'd like to suggest they have a longer retention period, so you can access more of your logs.
Unfortunately, there is nothing we can do for you to assist with this.
I hope this answers your question!"
