ProCall DataCenter system requirements
March 2026
Multi-server-environment
Setting up ProCall Infinity (DataCenter) requires knowledge of networks, administration and configuration in order to meet the system requirements.
In particular, the underlying databases (Redis and Microsoft SQL Server) must be brought online and made fully operational.
For the planning and commissioning of the entire architecture within the corporate network, service costs and system integration may be required.
The current version of ProCall DataCenter generally has the same system requirements as ProCall 8 Enterprise. The recommendations for system configuration are also the same as those for ProCall 8 Enterprise.
In addition, the following additional/specific system requirements must be met for the operation of ProCall Infinity:
Advanced/Special system requirements for ProCall DataCenter
A ProCall DataCenter multi-server environment always consists of at least two UCS servers that are connected to one another via a central database structure. The minimum system configuration is therefore as follows:
- 2x UCServer (including Media Server and Web Service)
- 1x Microsoft SQL Server database
- 1 Redis database
Redis
Hardware requirements
Please follow the general recommendations at Redis Docs.
Minimum system requirements
For use in conjunction with ProCall DataCenter, we recommend the following minimum system requirements:
- CPU: 8 cores at 3.6 GHz
- RAM: 16 GB
- Available storage space: 100 GB
- Network: at least 250 Mbps
Operating system
When choosing an operating system, please refer to the latest Redis documentation: Redis Docs.
In practice, a Linux distribution is the most widely used and most thoroughly tested option, and is therefore our recommendation.
Redis Version
To ensure that ProCall DataCenter runs successfully and efficiently, and to avoid security vulnerabilities, we recommend using the latest version of Redis.
System time
As ProCall DataCenter consists of several interconnected servers (a multi-server environment), it is important to ensure that the system times of the servers used are synchronised with one another. This is essential for correlating relevant log files in the event of an error.
Licences
The following licences are required to use ProCall DataCenter:
- per server: Each UCServer and Media Server running on its own machine requires a server licence.
- per user: Every user activated in the user management system requires a user licence.
This applies regardless of whether the user is currently actively using the client. Each user licence includes two line licences.
