I hope this is in the correct forum.
I have been trying to set up an Epson BX305FW to work as a fax on a shared telephone line/number.
I have followed the instructions in the manual to set up the fax. Everything checks out with the fax as the report shows PASS for each item.
The problem is that there is no phone line when the fax is connected. No dial tone, it actually sounds like there is a call in progress.
This happens whether you connect the phone into the back of the printer as suggested in the book or if you connect it to the splitter in the phone socket.
All the microfilters seem to be in order and you can get internet with the fax plugged in.
Any help much appreciated.
