As those of you who have worked with Exchange 2010 will know, it is possible for those using Exchange UM to have their incoming voicemails transcribed to text and shown with the messaging in their inbox.
The only issue is that currently we have support for voicemail preview in the following language packs:
- English (US) – (en-US)
- French (France) – (fr-FR)
- Italian – (it-IT)English (Canada) (en-CA)
- Polish (pl-PL)
- Portuguese (Portugal) (pt-PT)
- Spanish (Spain) (es-ES)
As you can see, English (UK) – (en-GB) is not supported for preview. Simply put this is because there are very many flavours of English in the UK and getting a single pack to correctly understand all of them to a suitable level of accuracy is a huge technical challenge.
With that in mind Microsoft needs to collect sample data (i.e. voicemails) to work with so as to improve the algorithm. So, if you would like to assist in the development of a English UK language pack which supports voicemail preview feel free to follow the steps below:
Voice mail collection is controlled with a setting on the UM Mailbox Policy object. This means that the UM administrator can choose which UM-enabled users’ voice mail is collected. This is important because there may be users that do not want to (or should not) have any of their voice mail collected: perhaps they receive voice mail with financially sensitive information.
To turn on collection for a UM Mailbox Policy, use the Exchange Management Shell (PowerShell) and set the AllowVoiceMailAnalysis property to true.
PS> Set-UMMailboxPolicy “some UM Mailbox Policy” –AllowVoiceMailAnalysis $true
The caller can prevent collection when they leave a message by pressing # instead of hanging up, and then choosing to mark the message private. This is also true if you are using the Protected Voice Mail feature.
