PCM File Requirements for Custom Ring Types
The PCM files for the rings must meet the following requirements for proper playback on
Cisco Unified 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.

• To create PCM files for custom phone rings, you can use any standard audio editing packages that
support these file format requirements.

Upload the new PCM files that you created to the Cisco TFTP server for each Cisco Unified
Communications Manager in your cluster. For more information, see the Cisco Unified Communications
Operating System Administration Guide, Software Upgrades.

DistinctiveRinglist.xml file.
