Chapter 1 Cisco Analog Telephone Adaptor Overview Software Features Note If the function button blinks slowly, the Cisco ATA cannot find the DHCP server. Check your Ethernet connections and make sure the DHCP server is available. Pressing the function button allows you to access to the voice configuration menu. For additional information about the voice configuration menu, see the "Voice Configuration Menu" section on page 3-22. Caution Never press the function button during an upgrade process. Doing so may interfere with the process.
