  Hi all,

   

  I`ve problems to communicate internal with external users.

   

  As you know, OCS / Live Meeting use 1024 to 65535 range port  for Streaming (UDP/TCP).

   

  Is there any way to "secure" this connection with a kind of conditional that only clients who already open a 5061 TCP (TLS) connection is allowed to traffic internal to external and external to internal 1024 to 65535 ports?

   

  Customizing is not an option. Many Windows Vista has "Audio not cofigured" error after enable "PortRange" in Registry.

   

  Regards,
