I have alexa on my android phon, an echo dot and an echo show. When I use alexa on my phone to video call my son it works fine, but when he trys to call me through alexa on his phone but my phone doesn't ring, instead the call goes to the echo show. My partner and I have the same issue, neither of us can call each other on our phones through alexa. I have followed all instructions and checked all settings. Stumped by this and would appreciate any ideas anyone has to fix this. Forgot to add, I can call my echo from my phone and connect fi e but when I call my phone from the echo the call comes through, as soon as I touch the green answer button on the phone it hangs up and the echo says I'm not available.
