    The Near-end Listen Port and Far-end Listen Port may have been modified within your Aura Signaling Group configuration.

    I saw this case and you can disable the "port translation" into virtual server configuration as well.

     

    I have a problem with SBC load balance when I need to change de IP address into the SIP INVITE, but I don´t get to do it.
