I am running CME 7.0 and configured extension mobility. After entering the username and PIN for EM login, the screen hangs dispaying "logging in". Pressing the exit softkeys shows that the user profile has been loaded succesfully. The issue is encounted during the logout process. Th screen just hangs, but pressing exit displays the correct screen. Any ideas what may be causing this? I'm runing IOS 12.4(20T) and 7941 phones.
