We have just encountered a "bug" which I am sure was not there before. You can no longer dial in to the conference room "connected to" your extension. eg extension 100 can no longer dial conference room 8100, extension 560 can no longer dial conference room 8560 etc etc If you try it just cuts off after a few seconds. Other extensions can dial the conference rooms with no problems.
The bug has been fixed. Please click the red bar to get the update.
