Watson Transcription (#4420) 

The following PR is for voicemail transcription using IBM Watson.
https://cloud.ibm.com/catalog/services/speech-to-text

The following values need to be configured in Default Settings:

Category: Voicemail
Subcategory: watson_key
type: text
Value: [Your Watson api key ]

Category: Voicemail
Subcategory: json_enabled
type: boolean
Value: true

Category: Voicemail
Subcategory: transcibe_language
type: text
Value: en-US

Category: Voicemail
Subcategory: transcribe_provider
type: text
Value: watson

Category: Voicemail
Subcategory: watson_url
type: text
Value: https://stream.watsonplatform.net/speech-to-text/api/v1/recognize?model=en-US_NarrowbandModel

Category: Voicemail
Subcategory: transcribe_enabled
type: boolean
Value: true


Reload Default Settings. I Flushed Cache and Reloaded XML just for good measure.

Also make sure transcription is set to TRUE in your voicemail box.
