It works this way:
If a buyer offers to buy your 1 BTC and pay by SEPA, the first step is to do you due diligence. "no discussion about identity, phone number and address" puts you in grave danger of being scammed. Scammers are known to use hacked IBAN accounts or stolen funds channeled or laundered on a third party account to buy coins. Another risk is called the MITM or Man In The Middle Scam. The scam usually involves placing fraudulent ads on classified advertisement websites. Goods offered are almost always high-ticket items such as phones, laptops, cars, jewelry, concert tickets, gemstones or just about anything. When a buyer offers to buy any of those advertised goods, the scammer contacts you for your IBAN information and identifies himself to the buyer as you (the BTC seller). The buyer sends payment by SEPA, thinking all along the payment is for a car or something. A few days later, when he realizes he was scammed, he will contact the authorities and report your IBAN account which is of course easily traced to... you! So be careful and try to at least conclusively identify the person buying your coins as the same exact person who will pay you.
When that part is completed, you and the buyer agree on which forum escrow to use on this list:

When you have established your choice of escrow, contact the escrow directly (buyer will also do this) and discuss the terms of the transaction. If the escrow agrees to act as middle man, you will be instructed to send the coins to the escrow's wallet. When the escrow confirms the coins are in his control, the buyer sends SEPA payment.
After you receive the money on your account, the final step is to instruct the escrow to release the bitcoins to the buyer. The escrow's role is to protect both you (the seller) and the buyer. Without escrow protection, if the buyer sends the money first you might take the money and not send any coins or if you send the coins first the buyer might not pay you.
A word of advice: contact the escrow directly here:

Do not rely on thread or profile links or email addresses given by the person you are transacting with. If you are asked to give your email address and instructed to wait for escrow's instructions, this is a red flag. Scammers are known to use fake or spoofed email addresses which look very similar to the genuine escrow's email address or they create a fake reproduction of the escrow's profile page or even an entire thread. The solution is to contact the escrow directly and to wait for that escrow to respond. Do not allow yourself to be pressured to bypass escrow and beware of the increments scam (the scammer suggest that you do the trade in increments or smaller amounts and you are expected to send first).
