    A request for help like this requires a lot more information about your XG configuration.

    Sophos XG230 is in Bridge mode

    Firstly, you need to identify what is failing eg review logviewer for the access of your PABX.

    What is the external address of each PABX and what would make them contact the main office PABX?

    Then you create the firewall rules covering the ports and sites.

    take the firewall log (log-viewer) and set the filter (search-field) to IP of telephone. try a call and check allowed/blocked packets.

    I think (if your phones connect directly to other phones) you will see dynamically used high-ports from RTP.

    Note: First set a time-range within logviewer before setting other filters ... otherwise search may need a lot of time.

    I created a  LAN to WAN firewall rule with a linked NAT rule and made the Main branch PaBX as source IP and the other branch PaBX as destination

    Also created another WAN to LAN rule and made the Main Branch pbx as the destination while the others are the source.

    However, i still have not yet seen success

    first: check firewall log for rules matching

    second: would suggest to use the "Server access assistant" to create inbound rules.

    I'm not sure but when your XG is in bridge mode I would think a linked NAT rule would not be necessary from LAN to WAN.
    I believe you only need to allow the traffic in XG.

    Firewall log may give you good clues on what is going on just as dirkkotte explained.

    How do I I allow traffic?

    Sorry for my questions which seem basic, am a first timer.

    When I installed it, it actually never allowed access to a remote database server until I disable some preinstalled rule.

    I also tried to block YouTube with several rules but still failed
