Hello, I have 4 lines that I use for my business. One of the lines, I use for after hour's calls. I have 2 users that use that login, as they rotate days. Since August 2021, I have had intermittent issues where the app does not actually ring, but when they go into the call log, they will see missed calls, many times there will also be a voice mail to accompany the call (so we know its not a wrong number).
I have tried multiple times with the support from ring central. I've heard many things from "Only use wifi" to "Only use Cellular Data" to "Reboot the Router" to "Restart the Phone" to "Reinstall the app". None of these things are consistently working. Both of my users experience this issue. They are both physically located in different locations. I have given them new phones, and tried using different cell carriers, and even that does not resolve my issue.
What is going on? I love my on call team, but I'm sick of taking calls from them at least once per week saying the phone isn't ringing for them. Please, please help me!
