  • Can you provide some more details as there are many reasons that Communicator calls might not work?  Does internal to internal work but not internal to external, or an no users getting audio regardless of their location?  What error do you receive?

  • Hi

    I did some tests and my results are as bellow


    internal to internal  - working

    External to External when both external users are on the same network(in same office outside the OCS network) - working

    internal to external - working when the external party has a public ip(when he is not behind NAT)


    external to external - not working (when the 2 external users are in 2 different networks)

    internal to external - not working (when the external user is behind nat)


    IM always works the above problem is there is voice and video


    my network setup is as Follows


    OCS running on a private ip

    Edge - internal interface running on a private IP.


    Then Edge Av server, web conferance server and access server on 3 different public IPS


    access server running on port 5061 Av and web conf.. server running on port 443

  • How is your default gateway configured? Should be on the external a/v interface.

  • Hi

    The av edge server must have ports 5000 to 59000 on udp and tcp. Also the public ip on av must be public facing and publicly routeable ( no natting allowed) . To allow sound to travel internal to external and visa versa.

  • HI

    I have this running with no firewall. all my ports are opened, i did this untill i get this working.

    network card on the on the OCS server does not have a gateway, but it can connect to the edge server private interface.


    my Edge server is in a public ip and it is configured with the an external gateway.


    is this correct ?


    OCE server

    IP -

    Subnet -

    Gateway - None



    Edge Server


    private interface

    IP -

    Subnet -

    Gateway - None


    Public interface

    IP - 202.59.X.X (public IP)

    Subnet -

    Gateway - 202.59.X.X (public Gateway)
