In a centralized multi-site network deployment, a FortiVoice local survivability solution provides resiliency with survivability branches. A survivability branch is a FortiVoice local survivable gateway (LSG) unit with local extensions. A FortiVoice LSG unit is located in a branch office. A FortiVoice phone system in a main office manages one or more FortiVoice LSG units (survivability branches).
Local survivability provides centralized management and branch office resiliency.
For details about deploying a FortiVoice LSG unit, see the FortiVoice Local Survivable Gateway Deployment Guide.
