The messageParts element contains the possible audio elements you have in a message. It is not a Rule by itself, but it will be part of every Rule in which a message is played to the caller.
You will play a message which has already been uploaded to our system. You may see these referred to as "Whispers". The XML for a Sound File is as follows:
Attributes are described in the following table
|soundLabel||The label of the sound file specified when uploading the file to our system||YES|
|soundGroup||You can organize your Sound Files in groups. The Sound Label has to be unique per Sound Group||NO|
Multiple soundFile elements can be provided inside a messageParts element.
