Now you've installed it, you must configure it correctly. There is already advice here for 'Unable to open 6000'; you should search for it.

But this "Unable to open 6000" not interfere in anything, I have this error in a2billing1.3.4 and not interfere in anything, this is an audio file, this is not the problem, if anyone can help I am grateful. Thanks
