可以通过ucma 5中的应用程序端点创建会议（而非用户端点）吗？ 这是我的代码：
ServerPlatformSettings serverPlatformSettings = new ServerPlatformSettings(_applicationName, _applicationHostFQDN, _applicationPort, _applicationGruu);
_serverCollabPlatform = new CollaborationPlatform(serverPlatformSettings);
_platformStartupCompleted.WaitOne();
ApplicationEndpointSettings appEndpointSettings = new ApplicationEndpointSettings(_applicationContactURI, _serverFqdn, 5061);
_applicationEndpoint = new ApplicationEndpoint(_serverCollabPlatform, appEndpointSettings);
_endpointInitCompletedEvent.Reset();
_endpointInitCompletedEvent.WaitOne();
ConferenceScheduleInformation conferenceScheduleInformation = new ConferenceScheduleInformation();
onferenceScheduleInformation.AccessLevel = ConferenceAccessLevel.Invited;
conferenceScheduleInformation.Description = "Conference Test";conferenceScheduleInformation.ExpiryTime = System.DateTime.Now.AddHours(5);
conferenceScheduleInformation.LobbyBypass = LobbyBypass.EnabledForGatewayParticipants;
conferenceScheduleInformation.AutomaticLeaderAssignment = AutomaticLeaderAssignment.Everyone;
ConferenceMcuInformation audioVideoMCU = new ConferenceMcuInformation(McuType.InstantMessaging);
conferenceScheduleInformation.Mcus.Add(audioVideoMCU);
_gatewayEndpoint.ConferenceServices.BeginScheduleConference(conferenceScheduleInformation,
EndScheduleConference, _gatewayEndpoint.ConferenceServices);
_waitForConferenceScheduling.WaitOne();
但是当执行此代码时，我看到了这个错误：
“当未指定代理或CollaborationPlatform不使用Mutual Tls时，ApplicationEndpoint上的操作无效。”
我为serverPlatformSettings设置了证书
ServerPlatformSettings serverPlatformSettings = new ServerPlatformSettings(_applicationName, _applicationHostFQDN, _applicationPort, _applicationGruu, certToUse);
但是当执行新代码时，我看到了这些错误：
通过一个证书：我看到了这个错误
