Hi Benjamin,
The difference between the two Encryption support level is the Encryption scope.
The cmdlet Set-csmediaconfiguration supports encyption to multimedia traffic (for example, audio and video transmissions) that travels between client endpoints and Mediation servers .
Trunk configuration Encryption support level is used to help protect traffic between the Mediation Server and the gateway or PBX.
You can select supportencryption for csmediaconfiguration and select Not Supported for Trunk Encryption Level. That means the multimedia traffic can be transport to meiation server with SRTP encrytion. But the mediation
server can decide to transport the multimedia traffic to gateway with encrypted or not.
