We are using ringcentral ringout call API for calling. But yesterday we saw this exception gets logged in Gibraltar for one of our user while calling. Please note we do login into C# sdk with users PhoneNumber, Password and PhoneExtension before they call. We tried to reproduce this exception again by using this users credentials for which we were getting this exception but we are now able to login and call without any error now. But we would like to know why this exception gets thrown while login (or may be while posting ringout API request) for this user.
Please refer below stack trace for more details :
