transactions are created for requests, you can use register_tmcb( 0, 0, 
TMCB_REQUEST_IN, your_callback_function, 0, 0 ) to get the callback 
executed for each new transaction. In this case you don't need to 
provide a valid sip message. You should register such callback in mod init.

Cheers,
Daniel
