I don't think this is true.
If you have specified that you don't want an assigned (preferred) LD carrier, then a LD call DIALED "by accident" would not complete. Random carrier assignments are only made for those customers who state that they DO want LD service but don't have a preference for which carrier is used. This usually only happens when a new line is activated (installed, connected, turned on ... whatever).
If you have specific information about a LEC that will do what you claim, please provide the details.
