This topic describes how to integrate your StarLeaf Cloud account with a Microsoft Skype for Business Online deployment.
For your own StarLeaf organization, and for all other StarLeaf organizations with which you want to communicate, you need to ensure that Skype for Business Online (Office 365) allows communication as follows:
1. Log in to portal.microsoftonline.com as an administrator for the Skype for Business organization.
2. Click on the Admin tile. This takes you to the Admin center.
3. Click on Admin centers > Skype for Business in the left-side panel. This takes you to the Skype for Business admin center.
4. Click on Organization then click on the external communications tab. Either:
Configure external access to On except for blocked domains and ensure <organization name>.call.sl is NOT present in the blocked or allowed domains table.
Configure external access to On only for allowed domains and ensure <organization name>.call.sl IS present in the blocked or allowed domains table.
Configure external access to Off completely. However, StarLeaf does not recommend this option as it is a security risk.
For each StarLeaf domain you wish to call, ensure your firewall allows traffic to/from the organization’s <organization name>.call.sl domain on the following in the following tables. If your firewall requires you to use IP addresses rather than DNS names, contact StarLeaf Support for the IP addresses. The following requirements are for outbound connections. Your firewall should also allow packets to flow inbound on established and related connections.
|From 365 Client||To StarLeaf Cloud||Edge server (destination)||Reason|
|UDP 50000-50059||UDP 50000-59999||5061||Audio/video media|
|TCP 50000-50059||TCP 50000-59999||5061||Screen-share media|
Successful communication between your Skype for Business Online (Office 365) clients and the StarLeaf Cloud also relies on your firewall being correctly configured for communication between the clients and the 365 server in the cloud. This is extensively documented at:
