The Basics

You will receive an invite from us via email. The link in the email takes you directly to the meeting and will prompt you to install any necessary software. Windows and Mac just install a small utility. Android and iPhone devices will instruct you to install the Zoom app.

Once in the meeting you will all be in a single room for joint session, then breakout rooms for each party can be set up and the mediator can jump between them. It’s actually very similar to how a real mediation would be conducted. We will even have a member of the Henning staff who will be there to assist.

Anyone who wants further information, please do not hesitate give us a call and we can walk you through the whole process. We have over 20 years of experience with video conferencing. You can also join a test meeting to familiarize yourself with Zoom.

More Details

Each meeting has a unique 9, 10, or 11-digit number called a meeting ID that will be required to join a Zoom meeting.

If you are joining via telephone, you will need the teleconferencing number provided in the invite.

Zoom has great tutorials to help you with any problems you may run into.
