Ok...

So, if one wants to use their VR, and do so over the phone, the number to call is:

1-877-429-8140

However...

If one were to misdial, and instead call:

1-877-729-8140

You would get an outgoing message that says:

'Enter the PIN number you wish, followed by the pound key.'

Not that I tested this, but, I certainly wouldn't advise that you enter your VR PIN in response to that prompt.
