The Call Park application supports only Windows Media audio (.wma) files for music on hold. You can use the Microsoft Expression Encoder 4 to customize files for music on hold. To download Expression Encoder 4, see http://go.microsoft.com/fwlink/?LinkId=202843. 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. |
