Fax is neither fish nor fowl. You can't consider it to be a phone request to let you provide oral pre-payment disclosures. It is most definitely not a mobile app or text message transaction, either. One argument you might make is that faxes are electronic, so you could make your pre-payment disclosure electronically, but that brings you to a blind alley because without ESIGN you cannot provide electronic receipts or combo disclosures.
I'll go out on a limb and suggest that if you have previously done the ESIGN dance to get authorization to make remittance transfer disclosures electronically (via email, for example), only then could you start with a fax request and complete the transaction.
If you can't go that way, I think you have to follow the fax request with a telephone call so you and the sender can complete the transaction by phone, which will allow you to follow the steps provided in the regulation for phone transactions.
Email is electronic, and you could do the pre-payment disclosure by return email. But before you could complete the transaction, wihch will require a written receipt, you will need ESIGN demonstrable consent to use electronic delivery of the receipt.
