Register a CDR handling engine.

Parameters:

	name	name associated with the particular CDR handler
	desc	description of the CDR handler
	be	function pointer to a CDR handler Used to register a Call Detail Record handler.

Return values:

	0	on success.
	-1	on error

Register a CDR driver. Each registered CDR driver generates a CDR

Returns:

0 on success, -1 on failure
