You can generate user device profiles for all users.
When you are inserting a file that was generated with the export utility, the export utility appends a numerical suffix_n for each line that is configured on a phone. For example, an export file with the name "sales_7960_1_3.txt" indicates that all phone records in this file have lines 1 and 3 configured. Use the appended suffixes to guide you in choosing a phone template with the correct line configuration during the UDP profile insertion.
You can use the dummy MAC address option when adding CTI ports. This option gives a unique device name to each CTI port in the form of dummy MAC addresses that you can manually update later using the
Cisco Unified Communications Manager Administration or the Unified CM Auto-Register phone Tool.
The dummy MAC address option automatically generates dummy MAC addresses in the following format:
where X represents any 12-character, hexadecimal (0-9 and A-F) number.
