    Hello, I have a 2 locations and my "out of LAN" phones can call and connect but there is no voice, it is a firewall problem when I disable the firewall everthing works fine. I need to know what ports should I open.

    Have you checked also 'PBX delivers audio' ON for these extensions ?
    The problem with audio could be peer-to-peer related.

    Regards.

    make sure that 9000 to 9049 (usually the defautes) UDP are open and not blocked.
