# Licensing

Server port and user capacity is controlled by a license file through the Applications Management Center (AMC), which is installed on the MiCollab server at the time of installation. The Licensing page shows the current number of ports available. You can create as many MiCollab Audio, Web and Video Conferencing user accounts on the system as MiCollab will allow, typically about 4,000. Additional Audio-only or Web-only licensing can be purchased and installed on the MiCollab server.

MiCollab Audio, Web and Video Conferencing 4.0 requires an Enhanced Video License to use the higher resolution video provided by the H.264 codec.
