Deployment Overview

A typical small-scale HA deployment places all SIP Voicemail components on a single server, with backup components mirrored on a second backup server. Components should be deployed as follows:

Primary Server	Backup Server
Primary Voicemail SIP Server Primary VM Server Resource Manager 1 (active) MCP 1	Backup Voicemail SIP Server Backup VM Server Resource Manager 2 (active) MCP 2

Note: The premise (agent) SIP Server is outside the scope of the SIP Voicemail HA configuration. If deployed in HA mode, either on the VM servers or on a separate server, a switchover from primary to backup Agent SIP Server does not impact the Genesys Voicemail components (Voicemail SIP Server, GVP Resource Manager, VM Server). To see a detailed architecture for this sample deployment layout, see the Basic Architecture diagram.
