IM Service

For optimal performance and scalability, the installation of the IM service can be configured depending on the number of users and the intensity of their use of the Instant Messaging (IM) feature.

  • For Fewer Than 1,000 Users: If your user base is under 1,000, you can install the IM service and the PBX service on the same server.

  • For More Than 1,000 Users or Heavy IM Usage: If you have a larger user base or if the IM feature is heavily used, it is recommended to install the IM service on a separate server to ensure better performance and scalability.

Up to 5,000 users
