The Faximum Messaging Server can be configured in four different ways to handle incoming faxes:
1. not to receive faxes at all
With this configuration the fax modems are not enable to receive and will ignore any incoming calls. This will also result in slightly faster sending of faxes since the fax scheduler does not need to tell the faxgetty daemon to release the modem for transmission each time it goes to send a fax.
2. to receive faxes and place them all in the unclaimed inbox
If neither form (see below) of automatic fax routing is available then FMS will place all received faxes into the unclaimed inbox. Any user with postmaster privilege (see "User Account, Adding/Modifying a" on page 75) can browse the faxes in the unclaimed inbox and route them to the intended recipient.
3. to receive faxes and route them based on DID number (FMS+PLUS only)
In short, DID (a.k.a. Direct Inward Dialling) enables you to assign each user his or her own unique fax phone number without having to pay for separate phone line for each user. Please see the next section ("Received Faxes, Automatic Routing of (FMS+PLUS only)" on page 55) for more information. NOTE this feature is only available with FMS+PLUS.
4. to receive faxes and route them based on multiple ISDN DN numbers
ISDN routing is the same as DID routing described above except using digital (i.e. ISDN) phone lines instead of analog phone lines. See also below.
