Hello Danilo,

in case of multiple PBXes you will see multiple incoming AppWebsocket connections from each PBX to your App Service. You have to use correct connection to send RCC messages for a specific User. My suspicion is, you send RCC messages on wrong connection.

For example, if you have PBX A and PBX B, with corresponding users Alice and Bob on each PBX, you have to send RCC messages for Bob on the AppWebsocket connection from the PBX B.

You can use the PbxApiConnection object to see from which PBX the incoming connection is established:
