That is good information. It indicates the Group message from the RemoteLinc button 3 On was received by EZSrve.
Since nothing was traced after the above, that puts the Action definition in question. Using the EZSrve Server Administration screen List Files offload the Actions.xml file and post or send the file to email@example.com if the file is too large to post. The Scene (links) between the RemoteLinc and EZSrve are good, something is not as expected with the Action definition.
