BR-DE-27 The seller telephone number should contain at least three digits
noun · XRechnung · warning · BT-42
For a sample invoice, the library reports: The seller contact telephone number (BT-42) should contain at least three digits, but "call us" contains 0. KoSIT raises this as a warning rather than an error, so the invoice will be accepted — but the number as written cannot be dialled.

xpath is always a UBL path. On a CII invoice, look for the
matching CII field instead.
