The Call Park application supports only WMA files for music on hold. You can use the Windows Media Encoder 9 Series tool available from http://go.microsoft.com/fwlink/?linkid=144677 to customize files for music on hold. Use the tool to convert the file to a WMA format. The recommended format for Call Park music-on-hold files is Media Audio 9, 44 kHz, 16 bits, Mono, CBR, 32 kbps.

Note:
The converted file plays over the phone only at 16 kHz, even if it was recorded at 44 kHz.
