We have developed a solution that receives webhook notification during calls. Our solution graduated from the Sandbox environment and is in working correctly in the production environment.
However, when I run our solution in our customer's sandbox environment, I am able to see the extension which I am interested in getting the call notifications, but we are not getting any notifications during calls. I suspect something is not configured correctly in the production environment, but what's the right way to troubleshoot this? I am not able to login as an administrator since this is not our account.
