Server role configuration

Last Updated : Jun 10, 2026 |

A telephony system consists of several virtual machines. Each virtual machine has a certain role, such as main or primary virtual machine, a second redundant virtual machine, Survivable Remote virtual machine, or Survivable Core virtual machine. Use Communication Manager System Management Interface to configure the virtual machine roles, and then configure at least two of the following fields.

  • Virtual machine settings

  • Survivable data

  • Memory

Communication Manager type and virtual machine role

The Communication Manager type determines the virtual machine role.

Note:

  • The Communication Manager Simplex and Duplex support Avaya Aura® Call Center Elite.

  • The Communication Manager Simplex and Duplex do not support Avaya Aura® Communication Manager Messaging.

You can configure the Communication Manager Duplex as one of the following:

  • Main server

  • Survivable core server

Note:

For a Communication Manager duplicated pair configuration, deploy the Communication Manager duplicated servers either on the VMware platform or on Avaya Solutions Platform 130. However, you can mix and match the deployment of the survivable core server, the survivable remote server, or the main server in a configuration. For example, the main servers can be a CM-duplicated pair on VMware, and the survivable core server can be on Avaya Solutions Platform 130.

You can configure the Communication Manager Simplex as one of the following:

  • Main server

  • Survivable core server (formerly called Enterprise Survivable Server [ESS])

  • Survivable remote server (formerly called Local Survivable Processor [LSP])

Important:

You can deploy the Communication Manager Simplex server and then administer the Communication Manager Simplex as a survivable remote server. However, you cannot administer a core Session Manager as a Branch Session Manager or a remote survivable server. Deploy the Session Manager as a core Session Manager only.
