PCM File Requirements for Custom Ring Types
The PCM files for the ring types must meet the following requirements for proper playback on
conference stations:
• Raw PCM (no header)
• 8000 samples per second
• 8 bits per sample
• uLaw compression
• Maximum ring size is 16080 samples
• Minimum ring size is 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 conference station rings, you can use any standard audio editing
packages that support these file format requirements
Configuring a Custom Conference Station Ring
To create custom conference station rings for the conference station, follow these steps:

Cisco
