Hello,
Thank you for your update on the issue.
As suggested by Mike Hall MVP, it is true that you cannot send a fax without the dial tone. If you have any ideas regarding what exactly you require while sending a fax and the procedure that would include faxing without having dialled the number, then please quote the steps that you want to follow. Your feedback is valuable and will help us improve our products in future or work on any limited areas of opportunity.
Thank you for your time and patience. Do let us know about any of your other recurring issues with Windows in future. We'll be glad to assist you further.
Regards.
