USING PHANTOMS TO ALLOW MULTIPLE USERS ON A PHONESET, EACH WITH A DID AND VOICEMAIL
Note: Switches with integrated voicemail, such as Meridian Mail or Call Pilot, should use ACDs instead of phantoms since ACDs don't use up licenses. In my experience with a Meridian 11c and Centigram voicemail (which is external to the switch), ACDs wouldn't work correctly.
The goal is to have one physical phoneset used by several users who each have their own dial-in number and voicemailbox. The physical phoneset is set up normally and has CLS SFA (Secondary Forwarding Allowed) added. Since we'll be forcing the phantom phones to forward to the physical one, we must let the physical phone forward the phantoms' DNs again to voicemail if nobody answers.
On the 11c, phantoms are built starting at loop 61 - check the documentation for your system if you have a different model. Pay particular attention to the CLS and FTR settings. For this example, the physical handset's DN is 3454, the phantom's DN is 3990 , and the voicemail DN is 3980.

Note DCFW 4 3454 - this forces the call on the phantom to forward to the physical phoneset. To change the physical phoneset's CLS to include SFA:

If you get a Loop out of range error message when trying to create a phantom
If you receive an error such as SCH0122, that means phantoms aren't enabled. First, check Common EQUipment in LD 22 to see whether SuperLoop N96 exists.

Each SuperLoop gives you the equivalent of four (4) 16-port analog cards (64 TNs). Card numbers in an 11c start at 61, so you can build phantom phones on 61 x, 62 x, 63 x, and 64 x. If you need to build more SuperLoops, use N100 next, N104, etc. (increase by 4).
When a phantom DN rings, it is forced to forward (DCFW) to the physical phoneset - users with displays can see the forwarded number and tell who should pick up. If nobody answers, the call is forwarded again (SFA) to the voicemail DN programmed in the phantom (FTR FDN xxxx).
Mailboxes are set up exactly as if the phantom phones were physical, with the phantom's extension as the mailbox extension number. The users will get no indication voicemail is waiting from a phantom phone, so they'll have to manually check it on their own.
Thanks to Gene Trout for help in figuring this all out.
