Explanation

When using the CUCM Auto-Register Phone Tool with a CSV file, the MAC address field is intentionally left blank. The Cisco Unified Communications Manager Bulk Administration Tool (BAT) is responsible for automatically populating the MAC addresses as phones auto-register with CUCM. When a new phone boots up and registers, it gets assigned a configuration from the CSV record matched by extension or line information. BAT then updates the record with the actual MAC address of the device once it checks in - this eliminates the need for an administrator to know MAC addresses in advance.
