after installing a new firewall and opened the recommended ports we are not able to dial out from a clearsea-client (on-premise) to public vc-systems, (tested it with a cloud-client).
Dial-in works fine.
When dialing out to the cloud-client there was a blocked incomming request on Port 1433 , after permit this communication it works.
Port 1433 normally is used for SQL-Server, why need the cloud client to communicate on this port, could not find anything about that in lifesize documentation.
Thanks for answers
