Had to connect a wireless all in one printer to my computer. I set up the phone line per instructions and nothing happened. I had a single to 2 line connector and tried that. No luck. Picked up this in-line coupler, hooked it up and printer, fax and computer are all happy and so am I.

It worked! My land-line phone now has great sound and the Coupler lengthened my land-line cord. The gold-plated connectors help to ensure a longer product life.
