Well, I certainly don't want to give this number to one of my clients... With just a simple internet search of the number and you get this:

[VOIPo] Setting up New Voipo account
832-838-7000 matches what I had from way back in beta. If the number scales, it would also be good to include in emails for new sign-ups.

To access the secondary mailbox for now, dial in to the remote voicemail access number 832-838-7000 and it'll ask for mailbox and password vs just password.
