Creating Custom Conference Station Rings
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:
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
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, refer to
Cisco Unified Communications Operating System Administration Guide,
“Software Upgrades” chapter.
Step 3
Use a 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 and for a sample Ringlist.xml file.
Step 4
Save your modifications and close the Ringlist.xml file.
Step 5
Cache the new Ringlist.xml file:
a.
Log on to Cisco Unified Communications Manager Administration.
b.
From the Navigation drop-down list at the top right of the window, select
Cisco Unified Serviceability
, and then press
Go
.
c.
