IPO R8 Essential with PRI. Last week a user got the same voicemail message forwarded to his email every 2-4 minutes, for hours. The message was deleted from the phone. I hoped it was a fluke but no luck. Yesterday it started to happen to another user. I turned on Monitor and can see the message sending, so it's coming from the IPO and not an issue with the email provider. Anyone seen this before or have any thoughts?
