Voice messages are normally stored in a compressed format. Although this reduces the storage requirements, it can cause problems if Unified Messaging is used in an environment that also uses audio compression, notably some Voice over IP infrastructures. Such use of multiple compression stages can result in the audio signal degrading, so that poor quality is experienced when listening to recorded messages.
Blueworx Voice Response and Unified Messaging Platform support the storage of voice messages in an uncompressed format. This facility can be used to maximize the quality of voice messages when they are used in an environment that employs its own compression mechanisms, for example a Voice over IP network using G.729A. The ability to use uncompressed messages is controlled using a Blueworx Voice Response system parameter called Voice Message Compression Type, which is in the Application Server Interface group . It can be set to compressed (default) or uncompressed.
