The API I'm making calls too is another DBUS interface, apparently with some functions being asynchronous, unfortunately the one in particular that I'm calling, isn't.

If the function you're calling takes a significant time, but can only be
called synchronously, then that's a bug in the library it comes from.
Try to use a better library... or failing that, use some sort of
worker-thread hack like I suggested before.

If your service is itself making a D-Bus call as a client (i.e. it's some
sort of proxy), note that all D-Bus method calls (in dbus-python and dbus-glib
at least) can be made synchronously or asynchronously, regardless of how the
service is implemented.
