What happens to the voicemails that my callers leave?

When you turn the voicemail "on" under Admin -> Phone -> Edit -> Settings -> Voicemail, it gets converted into a ticket in your portal with the recording added to the ticket. The ticket would along with the phone number and requester details if available. The only catch is that the voicemail needs to be more than 7 seconds in length for it to get converted to a ticket.
