# Limitations

# Number of users in a room

The number of users in a room is currently limited to 7 participants. This is due to the peer-to-peer architecture where a client's upsteam bandwidth is likely limited. In the near future this limitation will be increased, especially for server-based conferences and/or non-video participants. Depending on the system configuration, a MESH (conferenceType) call will be automatically upgrade to a SFU (selective forwaring unit) mode. The value autoUpgradeParticipantCount is available in the json response.
