Incorrect answer: ABCE
Configuring calling party normalization alleviates issues with toll bypass where the call is routed to
multiple locations over the IP WAN. In addition, it allows Cisco Unified Communications Manager to
distinguish the origin of the call to globalize or localize the calling party number for the phone user.
