Displaying the MAC Address of a Phone
The Media Access Control (MAC) address comprises a unique, 12-character, hexadecimal number that
identifies a Cisco Unified IP Phone or other hardware device. Locate the number on a label on the bottom
of the phone (for example, 000B6A409C405 for Cisco Unified IP Phone 7900 family of phones or
SS-00-0B-64-09-C4-05 for Cisco IP Phone SP 12+ and 30 VIP). Cisco Unified Communications
Manager makes the MAC address a required field for Cisco Unified IP Phone device configuration.
When you enter the MAC address in Cisco Unified Communications Manager fields, do not use spaces
or dashes and do not include the “SS” that may precede the MAC address on the label.
For more information on displaying the MAC Address or additional configuration settings on Cisco
Unified IP Phones, refer to the Cisco Unified IP Phone Administration Guide for Cisco Unified
Communications Manager that supports the phone model. To display the MAC address for the Cisco IP
Phone 12 Series and Cisco IP Phone 30 Series phones or the Cisco VG248 Gateway, perform the
following tasks:
• Cisco IP Phone 12 (SP +) Series and 30 Series (VIP)—Press ** to display the MAC address on the
second line of the LCD display.
• Cisco VG248 phone ports—The MAC address specifies the endpoint from the Gateway
Configuration window of Cisco Unified Communications Manager Administration. See the
“Gateway Configuration” section on page 90-1 for configuration information.
• Cisco VG224 phone ports—You can configure a Cisco VG224 gateway as an MGCP gateway or an
SCCP gateway. When it is configured as an SCCP gateway, it can have 24 analog phone endpoints.
When it is configured this way, it functions similarly to an IOS SCCP gateway. The MAC address
for each individual phone gets calculated by using a formula that considers the slot position, subunit,
port, and the last 10 characters of the original MAC address. See the
“Gateway Configuration”
section on page 90-1 for configuration information.
• Cisco IP Communicator—Get the MAC address from the network interface of the client PC on
which you want to install the Cisco IP Communicator application.
