Besides joining by phone, you can join via the Skype for Business Meeting app. This will provide improved audio and video capabilities as well as the ability to see any presented materials.
You may not have used this tool on your computer before and may need to set some things up first. We recomend downloading the application to allow for video. However the web app will work for seeing shared content and audio.
We have setup the following test meeting which you can join at any time to test out your connection. When you join there will most likely not be anyone else on the meeting but it should allow you an opportunity to download the app, become familar with the controls and make sure audio/video is working.
