In our previous phone system, users had the ability to access Department / Call Queue voicemail from their companion desktop app. They also had the ability to callback the caller that left the "group" voicemail. I am trying to provide them a solution that gives them similar functionality. So far I have given them access to the web portal with the login for that Call Queue, but they do not have the ability to click a number and ring out to their phone because they are not logged in themselves.

1. Is there a way to download a voicemail from a mailbox using the API?
2. Is there a way to play a voicemail over a users phone by initiating it from the API? aka I want to play a wav file over the users phone.

Thanks
