Question about HP 640 Inkjet Fax Machine
New HP 640 fax has been working fine until we tried to fax something to a fax number with the area code of 817 (Texas). Faxes to this area code will not go through. Local faxes and faxes to numbers in our state (Tennessee) are fine. We get a "Sending Confirm" page printed after the aborted fax. It says "Mode: ECM" and "Result: Send Error."
Hope you can help.
If you need it, my email is firstname.lastname@example.org
The recipient may have a DSL phone line, or receiving to a fax server that blocks your area code.
