Callbacks, when the callback module is unknown (undefined), results in warning messages.
A race condition scenario. As part of a cancelation operation, replies with waiting acknowledgements is cancelled. This includes informing the user (via a call to the handle_trans_ack callback function). It is possible that at this point the connection data has been removed, which makes it impossible for megaco to perform this operation, resulting in the warning message. The solution is to also store the callback module with the other reply information, to be used when cleaning up after a cancelation.
