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
• Mu-law compression
• Maximum ring size = 16080 samples
• Minimum ring size = 240 samples
• Number of samples in the ring = multiple of 240.
• Ring start and end at zero crossing.
To create PCM files for custom phone rings, use any standard audio editing package that supports these file
format requirements.
