Hello there, TrudyVan here
The best way to set up a conference room to connect family members is easy with our new conference rooms.
All you do is send via an email and give them the url link to your conference room telling them the date and time all of you will be in the room.
That is how I do it. Give them at least 3 days notice.
Hope this answers your question and if there is any further information that you require.
