Video-users are associated with Phone.com extensions. A video user is a collection of a domain name for the bridge id, a business name, and a plan which affects the bridge capabilities in terms of maximum participants. Normally each video-user is billed to the account and the pay is based on the plan selected.
Create a user video for extension. The user will receive an email with steps to connect to their video bridge and additional operational instructions.
