# Genesys Quality Management Suite 8.1.520 : Call Recording Core

Created and last modified by

Go to Settings > Configuration > CallREC Core > CallREC Core.

In this section you can find configuration of the CORE module itself.
You might want to change the CORE module's server in a multiserver deployment. In single server deployments these settings are not changed.

1. Registry address: Specification of the server where the CORE module is running. Default: core.
2. API registry address. Specification of the server where RMI API is running. The service is a part of the CORE module so it should point to the same server where the CORE module is. Default: core.
3. Observe core enables connections from RMI. We do not recommend changing it's value. Default: checked.
4. Core RMI.
   - If specified then the port is used for RMI callbacks. Make sure that the port is not blocked between the servers in a multiserver deployment.
   - If it's set to 0, then it takes any free port for the RMI callbacks.
