The concurrent seat license works well for companies that have meetings of over 4 participants on a regular basis. Advantages include the ability to host larger meetings with more than 4 participants, the ability to have multiple meetings running simultaneously, the ability to add seats to the license, as well as having your own company-branded Webex site for you and your participants. Licenses can be created in any size (minimum of 4 seats) to fit your meeting needs and budget.
