Creating Custom Phone Rings
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 is evenly divisible by 240.
• Ring starts and ends at the zero crossing.
• To create PCM files for custom phone rings, you can use any standard audio
editing packages that support these file format requirements.
Configuring a Custom Phone Ring
To create custom phone rings for the Cisco IP Phone 7961G/7961G-GE and
7941G/7941G-GE, follow these steps:
Procedure
Step 1 Create a PCM file for each custom ring (one ring per file). Ensure the PCM files
comply with the format guidelines that are listed in the “PCM File Requirements
for Custom Ring Types” section on page 6-3.
Step 2 Place the new PCM files that you created in the C:\Program Files\Cisco\
TFTPPath directory on the Cisco TFTP server for each Cisco CallManager in
your cluster.
Step 3 Use an text editor to edit the RingList.xml file. See the “RingList.xml File Format
Requirements” section on page 6-2 for information about how to format this file
