You can set your custom coverpage where you can customize the senders and receivers info:
In case of API, "If you want to use your own custom cover page, disable the system cover page by setting
0 and then adding your own cover page as the first page of your fax message. "
Also you can check this: https://community.ringcentral.com/questions/987/online-fax-customize-cover-sheet.html
