SOLUTION: Ok, there's two problems that occurred with the VM. One, when a caller dials an extension the phone repeatedly rings and never goes to voice mail. Turn off call transfer in the VM Transfer/Delivery options.
Secondly, the caller dials an extension and the phone sends the caller straight to voice mail. Find out the Voice Mail Box system phone number by pressing the Voice Mail button and see what number the extention points to. For example.. [134]-->[This Number]. Then hang up and press the SPKR button, press 43, and then dial the VM System phone number.
Works for us at least. Cheers!
