check SipService, NativeService and other such services, Mainly the NgnStack should contain some helpers for you. If these are not inside the application, then you might be out of luck as you may need to download and compile the source of Doubango Library to access the code and enter log messages to get them,. .. If you are seeing them under the Log tag "DOUBANGO INFO: " then rest assured they are coming from the JNI library and if you don't find any helper methods. Then you have to look in the Doubango C/C++ sources of modules like tinyDAV, tinySIP etc.
