OpenSIPS IMS - Community Edition - Configuration

The OpenSIPS IMS Community Edition scripts can be configured using environment variables. These variables are utilized by the OpenSIPS pre-processing script (via the -p parameter) at startup, so they must be exported in the environment where each component is running.

Note: Docker Open5GS already includes all these variables in the .env file, so you don't necessarily need to explicitely tune them unless really needed.

Environment Variables

The following environemnt variables are being used:
