The Configuration module allows you to apply various configuration settings to the DID’s within your inventory. Please note that you will need to have certain features (eg. VoxOut International) enabled on your account before you are able to apply those settings to your DIDs.
applyConfiguration method: This API is used to configure a one or multiple DIDs with certain settings. Please note that if you get an error message for one DID, then you should consider that none of the DIDs in your request will get the requested configuration and you should resubmit the request with the necessary changes.
In 2018, we will be deprecating this method. Hence it is recommended that you use the applyDIDConfiguration method for all your configuration requirements.
