Brekeke PBX Redundancy

Network Setup:


Root privilege is required by Brekeke Redundancy.
we recommend RedHat, CentOS and Fedora for Linux server.


  1. Install Brekeke PBX version 2.2 or later on two pc, one is primary server, the other is secondary server.
    Both servers need to have license with options for the "Redundancy" option.
  2. Keep the same system time on both Brekeke servers.
  3. The settings on both PBX should be the same at the beginning,
    Such as, PBX users, ARS rules, network interface addresses at bundled SIP Server, dial plans, user authentication settings...
    You can backup primary settings and restore it on secondary to let both server setting identical
  4. Two IP addresses are needed at primary server:
    one is in the same IP segment as the IP on secondary server
    the other IP address needs to be in a different IP address segment from the secondary server IP addresses. And this IP address will be used as vitrual IP address
    In above sample network setup:
    VIRTRUAL_IP_ADDRESS: /, the primary IP which is in different segment from secondary server IP.
    Gateway IP address:
  5. If there is a firewall on primary server, please configure it to accept ICMP packets sent from the secondary server.
  6. Set port forwarding at router which Brekeke PBX are behind and forward SIP and RTP ports to VIRTUAL IP ADDRESS
    This VIRTUAL_IP_ADDRESS is assigned on primary server at the beginning.
    When failover happens, Brekeke heartbeat action will add VIRTUAL_IP_ADDRESS on secondary server
  7. The accounts under Brekeke PBX bundled SIP server > [Aliases] will not be mirrored on secondary server.
    Please use shared third party database or other solutions to synchronize user authentication accounts on both primary and secondary servers.
    If shared third party database is used at both primary and secondary Brekeke PBX bundled SIP server, do not need to set up mirroring at both servers any more.
  8. If authentication for REGISTER and INVITE is ON, set the same realm name at both primary and secondary Brekeke SIP Server admintool > [configuration] > [SIP] > [Authentication] > [Realm(ex. domain name)]
  9. For UAs/phones in the same LAN as Brekeke PBX server, VIRTUAL_IP_ADDRESS should be used as registrar and proxy address. And UA/phone should send REGISTER or INVITE requests to VIRTUAL_IP_ADDRESS
    For UAs/phones at WAN, the router global IP should be used as registrar and proxy address at UAs/phone settings.
