Cisco IP Phone Requirements
Cisco ITS Version 2.02 supports the following Cisco IP phones:
• Cisco IP Phone 7910
• Cisco IP Phone 7940
• Cisco IP Phone 7960
• Cisco IP Conference Station 7935
• ATA - 18 6
Firmware Requirements
The most current Cisco IP phone firmware versions are at
http://www.cisco.com/cgi-bin/tablebuild.pl/ip-key.
The Cisco multiservice routers provide support for updating and storing of Cisco IP phone firmware.
The Cisco IOS Telephony Service router also provides TFTP support for downloading the phone
firmware files to the phone.
Note When installing new Cisco IP phones to an ITS ATA device configuration, remove the tftp-server
flash:XMLDefault.cnf.xml command temporarily (see link to Configuration Example, at the end of
Chapter 2) until the new phones are installed properly. After the phones are installed and working
correctly, restore the tftp-server flash:XMLDefault.cnf.xml command.
A way to verify correct phone load installation is to set registration debugging with the debug ephone
register command, reset the phones, and look at the StationAlarmMessage displayed during phone
re-registration. The "Load=" parameter should appear in the display, followed by an abbreviated version
name corresponding to the phone load file name.
