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 on the fly. 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.

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-200F8
  • FVE-500F

Local survivability deployment

Follow these recommended general steps to deploy your local survivability network:

  • Set up HA on the central unit

    It is important to get your HA up and running and the correct virtual IP set as it is used throughout the local survivability setup. For information on setting up HA, see Using high availability.

  • Add or import extensions to the central unit

    Once each branch unit has been added, you can add or import their extensions to the central unit. For more information, see Configuring IP extensions.

  • Add and configure each branch unit:
  • Apply branch configuration from central unit

    Once the branch unit is set to the correct IP address, you can apply the configuration from the central system to each branch. See Adding, configuring, and viewing survivability branches.

  • Add phones to network at branch offices

    Once the branch unit has received the configuration file, add the phones to the network. They will automatically detect the branch unit and be redirected to the central office to get their configuration file.

    Note

    Adding the phones to the network too early will result in receiving an unassigned phone configuration file from the branch system. The phones need to be set to factory default for them to go to the central unit to get their configuration file.

Adding, configuring, and viewing survivability branches
