How to partition a 3300ICP Embedded VM with seperate 0 destinations

The 3300ICP's embedded VM is a nice quick-n-dirty VM system for most small/medium installations. However, if you're like me, you'll come across a situation where you'll need to split it into multiple auto-attendants. This can be a real pain, but here's how I do it:

- Create a seperate VoiceMail hunt group for each AA you need, and add VM ports to it. For example, if you need 2 seperate AA's, assign HG 2001 with VM ports 1001-1010, and HG 2002 with VM ports 1011-1020.

- In Greetings Assignment, change the default greeting for each port to match the AA they belong to. For our 2-AA example, assign ports 1-10 to Primary Greeting 1, and use Alternate Greeting 2 for ports 11-20. Record your greetings using the Adminstrator's mailbox.

- Program your menu nodes and mailboxes as usual.

- Program your main greeting 0 destination. Here's where things get sticky. If each AA needs a seperate destination for the 0 option from the main greeting, a bit more work is involved. We'll be using Interconnect Restriction and Intercept Handling to help us guide calls to the correct destination; this is done by intentionally creating a restriction, then sending the call to a new destination.
- First, set up 2 interconnects for each AA; one for the ports, and one for the 0 destination. Restrict ports for AA 1 from the 0 Destination of AA 2, and vice versa. Assign the appropriate interconnect number to the ports and devices.
- Set up an Intercept Handling set for all but the first AA, assigning your 0 destination DN for the Interconnect Restriction option. Assign the VM ports to the appropriate Intercept number.
- Program AA #1's 0 destination as the Operator Mailbox extension.

The theory works like this:
Caller enters HG 2001, hears the greeting for AA 1, dials 0. 3300 looks at the extension assigned to mailbox 0 and transfers the call.

Caller enters HG 2002, hears the greeting assinged (Alternate Greeting #2 in our case), and dials 0. Since the DN assigned as the extension for the Operator mailbox is restricted, Intercept handling will step in and send the call to the DN we've defined in the Intercept Handling form.
