If calls are being immediately routed to someone's personal voicemail, you may also want to check whether "transfer" options are available for the mailbox. If "transfer to extension" is turned off in a personal mailbox, calls routed via the auto attendant will immediately route to the person's mailbox, rather than ringing their phone first. If "transfer to extension" is turned on in a personal mailbox, calls routed via the auto attendant will ring the phone and forward to voicemail after the specified number of rings.
