Hi XW,
I meet the same problem as yours. I do not use a 2-line phone, but a Brother mfc845cw phone, which use 2-cord line. The phone line just has 2 cords. When I plug this fax phone in line1 port. The fax phone can receive both line1 and line2 calls. But when I plug it in line2 port. It only can receive line2 calls. What is your advice? if you need the config file, I can attach it.
Thanks in advance!
Jay
