Fax Service

I’m using the Windows Fax Service to send/receive faxes. I currently have 2 fax lines hooked up. Both lines are set up to send. I’ve temporarily disabled receiving on both lines.

When I send multiple faxes the same time, I would expect the first fax to begin on line 1, then the second to begin on line 2; however, windows will not use line 2 at all. It sends the first fax on line 1, then the second on line 1, etc.

Has anyone sucessfully done this in the past? Any ideas on what to do?

Thanks.
