Starting about 3 days ago (at least that's when I first noticed), when I answer a call from my DS2 front door I can see/hear the person at the door, but they cannot hear me. I tried the DS2 on my gate and also tried calling my touch screen, and the same issue on all 3. I have an Android phone, so I tried using the app on an iPhone and we are having the same issue. Rebooting the EA-3 and the POE switch did not help. Drivers are up to date and nothing has been changed recently. Anyone else come across this issue or have any suggestions?
