+ * Register support for SIP TCP transport by creating TCP listener on

  * @param endpt		The SIP endpoint.
- * @param local		Local address to bind.
- * @param async_cnt	Number of simultaneous async operations.
+ * @param local		Optional local address to bind, or specify the
+ *			address to bind the server socket to. Both IP 
+ *			interface address and port fields are optional.
+ *			If IP interface address is not specified, socket
+ *			will be bound to PJ_INADDR_ANY. If port is not
+ *			specified, socket will be bound to any port
+ *			selected by the operating system.
+ * @param async_cnt	Number of simultaneous asynchronous accept()
+ *			operations to be supported. It is recommended that
+ *			the number here corresponds to the number of
+ *			processors in the system (or the number of SIP
+ *			worker threads).
+ * @param p_factory	Optional pointer to receive the instance of the
+ *			SIP TCP transport factory just created.
  *
  * @return		PJ_SUCCESS when the transport has been successfully
  *			started and registered to transport manager, or
