Configuring local survivability

FortiVoice local survivability solution is designed to provide branch resiliency for centralized deployments with multi-sites. The FortiVoice unit at the central office sends the configuration files to the FortiVoice units and extensions at the branch offices. The central office handles all inbound calls thereby consolidating the number of lines required for an organization.

With this solution, you have one place to look for the routing rules, logs, call records, and call recordings. You can see the whole setup, make changes, or modify records. If an extension is added, it is operational immediately. Any users at any location will be able to call that new extension right away without waiting for configurations to sync up, or new policies required to be set at each location.

If the communication between the FortiVoice unit at the central office and the FortiVoice units and extensions at the branch offices is down, the FortiVoice units at the branch offices (survivability branches) will kick in to provide access to lines until the communication is restored between the central unit and the extensions.

A survivability branch is a local FortiVoice unit containing local extensions that is part of a centralized deployment.

For detailed instructions about deploying a survivability branch, see the FortiVoice Local Survivable Gateway Deployment Guide.

The following FortiVoice phone system models can manage one or more survivability branches:

• FVE-300E-T and larger
• FVE-VM-500 and larger

The supported FortiVoice survivability branch models are:

• FVE-20E2
• FVE-20E4
• FVE-50E6
• FVE-100E
• FVE-100F
• FVE-200F8
• FVE-500F
