Wired Expansion Microphone

The Cisco Webex Room Phone supports two wired expansion microphones, available in an optional kit. Use
the expansion microphones in larger rooms or in a crowded room. For best results, we recommend that you
place the microphones between 3 feet (0.91 m) and 7 feet (2.1 m) away from the phone.

Phone Firmware and Upgrades

Your phone comes pre-installed with firmware that is specific to the call control system.
Occasionally, your administrator upgrades the phone firmware for you. This upgrade happens when you are
not using your phone because the phone resets to use the new firmware.

Additional Help and Information

If you have questions about the functions available on your phone, contact your administrator.
The Cisco website (https://www.cisco.com) contains more information about the phones and call control
systems.
