Voice Message Compression Type

Parameter group

Access level


Possible values





Specifies whether voice messages are recorded in a compressed or uncompressed format, when using the RecordVoiceMessage state table action.

You should set this parameter when you install Blueworx Voice Response, and then not change it afterwards. This prevents you having both compressed and uncompressed voice messages on the same system—Blueworx Voice Response can then search more effectively.

Note that an uncompressed voice message occupies 5 times more disk space than it would do when compressed.

If the messages you are recording are of reduced quality, for example because they originate from a mobile phone or compressed voice-over-IP network, then using uncompressed rather than compressed message storage within Blueworx Voice Response can improve the playback quality.

If you want to change this parameter from its default setting, ensure that all your custom servers that use the CA_Get_Voice_Msg_Info subroutine can process a returned VOICE_MSG_INFO_ST structure in which the compression_type field can have any valid value. If you do not, the data returned will become corrupted.

Restart your Blueworx Voice Response system after changing this parameter.
