Question about 470 and an OIP server

[edbmam]

I have a Mitel 470 and an OIP server which we use as labs.
We are strengthening the security in our office and for that we are restricting the access of our computers to the Internet. The question is: What are the pages and ports to which they need to connect to validate licenses or for other queries to the cloud?

There is a MiVoice Office 400 TCP/UDP Port Usage document that has all the ports used related to the MiVo 400.
