I am trying to manually remove members from a conference from the status web page but I am having troubles closing down the connection properly. I have access to the conference manager and the conference connection. When I call H323Connection::ClearCall(), it severs the connection to the endpoint and the member is removed after ConferenceManager::RemoveMember is called but there is a segmentation fault because the logical channel threads are still running. I keep getting the following assertion failure:

2008/08/06 15:26:39.089    HTTP Service:0xb50f9b90    Message    Assertion fail: Transport thread did not terminate, file transports.cxx, line 1355, Error=107

I was wondering if anyone knows how to close down a call properly.
