Creating custom ring tones for Communications Manager Express (CME), or how do I get my phone the ring tone from the Fox TV show 24?
Custom Ring Tones for CME is a five step process.
Step 1 - Convert a .wav file to PCM format with a .raw extension
Step 2 - Create or modify the RingList.xml file on the CME Router
Step 3 - Upload the ringtone and RingList.xml files to the CME Router
Step 4 - Enable the TFTP process on the router to server the files.
Step 5 - Reset the phones
STEP 1 Convert a .wav file to Raw PCM
The easiest way to convert a .wav file to PCM format is using Sound Recorder, a program that usually comes installed with windows as a default. Please note the Sound Recorder that comes with Windows Vista does NOT offer this functionality.
Open the .wav file with Sound Recorder and click save as.
change the format to CCITT u-Law and 8.000khz, 8bit, then save it with a .raw extenstion.
Technically Cisco States the following:
PCM File Requirements for Custom Ring Types
The PCM files for the rings must meet the following requirements for proper playback on Cisco IP Phones:
- Raw PCM (no header)
- 8000 samples per second
- 8 bits per sample
- uLaw compression
- Maximum ring size — 16080 samples
- Minimum ring size — 240 samples
- Number of samples in the ring must be evenly divisible by 240
- Ring should start and end at the zero crossing
Cisco's Requirements are documented at http://www.cisco.com/univercd/cc/td/doc/product/voice/c_callmg/3_0/admin_gd/3_0_9/a3rings.htm
STEP 2 - Create or modify the RingList.xml file on the CME Router
RingList.xml is a case sensitive file used to globally configure available ringtones on the CallManager Express router. You can copy the sample format from below into notepad and save it as RingList.xml. This file provides the list the users browse to select ringtones and the file locations the IPphone uses to find the ringtone files served up by the TFTP service on the CME router. You can have up to 50 entries in this file. The descriptions and filenames have a 25 character limit.
<CiscoIPPhoneRingList>
<Ring>
<DisplayName>MyCustomtone</DisplayName>
<FileName>mycustomtone.raw</FileName>
</Ring>
<Ring>
<DisplayName>RingTonefrom24</DisplayName>
<FileName>ctu.raw</FileName>
</Ring>
</CiscoIPPhoneRingList>
Cisco now provides a Sample RingList.xml file and Sample Ringtones at the CME section of the Software Download site. The Package does not however have the ringtone from the TV show 24. (All customers ask for this Ringtone)
STEP 3 - Upload the ringtone and RingList.xml files to the CME Router
Use the command copy tftp flash:RingList.xml and copy tftp flash:YOURringTONEname.raw
Follow our instructions on how to use TFTP or a USB flash card to upload files to the CallManager Express Router's flash.
STEP 4 - Enable the TFTP process on the router to server the files.
Enter the command tftp-server flash:RingList.xml and tftp-server flash:YOURringTONEname.raw
The tftp-server command enables the TFTP server function of the router to be able to deliver the RingList .xml and specific ringtones to the phones.
STEP 5 - Reset the phones
Reset an individual phone to test your ringtones before using the telephony-service reset all command.
