Lifesize Cloud says:
- Firewall configured to allow TCP/TLS port 5061 and TCP/UDP ports 30000-50000 to and from Lifesize Cloud Lync Server
Why is that stating FROM Lifesize Cloud Lync Server? Shouldn't destination ports be defined by the customers Lync Environment?
Is there no usage of 443 or 3478 possible between federated Lync environments?
