On the PBX side, the Voice mail ports must be unrestricted, port 4 on a 4 port system, ports 5&6 on a 6 port system. Those "estensions" must be set to unrestricted in extension programming, and set the ARS restriction to 3 or higher. Enable trunk transfer on those extensions.
On the voice mail side, the mailbox must be set to allow outcalling in system programming, and the individual user must set the mailbox to 1)Turn on outcalling, and 2) Set up the outcalling number. When you test, observe the lights on the Mail system, the outcalling port should come on about 5-10 seconds after leaving the message. Make sure the outcalling number includes a "9" if in the Hybrid PBX mode.
