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.

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