Hi Dennis,
When you say convert voicemails into tasks, do you mean Team Messaging Tasks or tasks on a third party system? With the API you should be able to receive a webhook notification on these events that you can then use to create a task (either with the Team Messaging API or with a third party service API).

For attachments, you should be able to pull the data from the webhook or get the recording to then store either as an attachment (again depending on where you want the task to live).

Here is more on our webhooks and creating tasks via the API.

Hope this helps,
Mike
