Hi @coralievachet1, welcome to our forum!
I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.
To record calls you will need to download a third party application from the Google Play store as the device does not have such a feature by default.
If you just search for "call recording" or "record calls" in the Google Play store, there should be plenty of options to choose from.
I hope that helps!
