My current network consists of a Apple Airport Extreme and an Apple Airport Express. I have added the Express to the Extreme to create a WDS.
I wonder if I can plug at ATA into the Express ethernet point to set up VOIP. I know I can add the ATA to the Extreme but I need the voip where the Express is as there is no cable there. I don't want to buy a ATA to find out it won't work.
