Hi there, I have the following simple test script running in mod_managed: Session.Answer(); string Uuid = fsApi.ExecuteString("create_uuid"); string originateString = string.Format(@"{{ignore_early_media=true}}[origination_uuid={0}]user/3478309995@64.40.xx.xxx'&park'", Uuid); apiResult = fsApi.Execute("originate", originateString); Session.Hangup("NORMAL_CLEARING"); When I run this script and I anwser the call, the console shows the error message: [CRIT] switch_core_session.c:1287 Duplicate UUID! However 'show channels' reveals that the UUID is the expected value (that given in origination_uuid=), when the call is ringing and after it is answered. It is as if, FS is creating the call with the given UUID, and then on answer trying to set the UUID to the given UUID again, but failing when it see the existing call. I updated to the latest GIT HEAD just before sending this email. Any ideas? Is this something I should be worried about - or am I using origination_uuid incorrectly?
