We are using .net fax object to send fax to right fax server. see below code-
oFax = mRightFaxComServer.Faxes[faxFileInfo.RightFaxSettings.RightFaxServerObject].Create;
oFax.OwnerID = faxFileInfo.RightFaxSettings.OwnerId;
oFax.ToName = recipientDetails.RecipientName;
oFax.ToFaxNumber = recipientDetails.FaxNumber;
oFax.FromName = recipientDetails.SenderName;
oFax.Attachments.Add(fileName);
oFax.NeedsPDFConversion = true;
oFax.isFineMode = true;
oFax.NeedsPreScan = true;
oFax.CoverSheetNotes[1] = recipientDetails.Notes;
This line added to send cover sheet notes but we are not able to see notes population on cover sheet.
Above code works for version 9.6 as expected
