Telephones and 24 (the TV series)

Having watched 24 (the TV series), I have always wanted a Cisco phone that would ring with the same ringtone as used by CTU. To get the ringtone onto the phones I needed to enable the TFTP server on the router and edit the ringlist.xml file as so:

<CiscoIPPhoneRingList>
    <Ring>
        <DisplayName>CTU 24</DisplayName>
        <FileName>ctu.raw</FileName>
    </Ring>
</CiscoIPPhoneRingList>

Having tried to follow the Cisco guidelines to create the ringtone myself (unsuccessfully - it kept skipping and not repeating itself correctly), I stumbled upon a site that allowed me to download a ringtone that worked. When I copied the ringtone to my router and reset the phones then I was in business.

Below are some images of my Cisco 7912G phone hooked up to Unified CallManager Express running on my Cisco 2801 router.
