Please allow voice mail messages to be sent to multiple email addresses, at least two. This seems to be one of the few cloud based PBXs that only allows voice mail to be sent to a single email addres...
For customers that use Office 365, I created a Shared Mailbox, and assigned the users that need access to voicemails to that Shared box. Sending voicemails to this box (voicemail@company.com) allows everyone to see them, and then they can use the QuickSteps (right click the email in Outlook) option to mark the job Done in Outlook (adds a little green check to the email).
While this wouldn't work for non-O365 users, this would make it easier for multiple recipients to manage the voicemail, as there would be a fairly easy way to discern whether one person has handled the voicemail or not. If they're using only O365 webmail, you could possibly create a category called Complete, and add a color to indicate that it's been completed (I believe QuickSteps is only available in the Outlook Program).
Otherwise, yes, having multiple emails would be very handy!
