Doorbell Elite POE and two way call

Just want to share my great experience with Doorbell Elite. The POE has never been down for couple of years so far. What a stable product the Elite is! Also today I had a very clear two way call with a visitor. The sound had never been so echo free. We could hear each other so well. Just one or two months ago I could not even hear the visitor due to the echo. I guess a recent app or fw update solved the problem finally. Ring doorbell team, kudos to your great work!
