Mitel NuPoint Messenger Technical Documentation - Release 7.0
 
If you have created mailboxes but have not yet assigned them to users, you can use an FCOS to 
deny login (feature bit 001). 
To ensure that a new mailbox, once assigned, is not used until the owner accesses it, you can 
require initialization from the integrated telephone number (feature bit 142). You can also set the 
FCOS to prevent messages from being received until the mailbox has been initialized (feature bit 
127). 
Note:  Feature bit 142 (Must run tutorial from own phone) is not supported for all integrations. 
Line Groups 
By dividing the total number of ports in your server into line groups, you can increase the security 
for specific applications. You can configure each application to be on a different line group, and 
enable an appropriate level of security for each application. 
Separating the applications by line group can help prevent certain types of abuse, such as 
connecting from one application to another. Incoming and outgoing calls occur on separate line 
groups in a server. This keeps hackers from reaching the server and then dialing out through the 
NP Receptionist or another application. 
You can restrict access to certain line groups, like a toll-free dial-in line group, by setting the 
FCOS to require callers to enter an access code before hearing the regular line group greeting 
(feature bit 160). If a caller exits one mailbox, the server requires reentry of the access code 
before allowing further progress through the server. You can also use FCOSs to completely deny 
login on specific line groups (feature bits 101-109), or ensure that mailboxes cannot receive 
messages when the call is received on a specific line group (feature bits 111-119). 
Telephone Answering 
Outside callers can abuse access to a server during a telephone answering call by trying to break 
into the dialed mailbox or access other features. By correctly setting the line groups and FCOSs 
in your server, you can control the feature set available during an answering session. 
You can force the termination of telephone answering sessions after callers leave a single 
message by setting the line group to not allow multiple messages for outside callers. For 
Greeting-Only mailboxes, you can have the server hang up immediately after playing the greeting 
(feature bit 062), call the mailbox attendant after the greeting (bit 063), or call the mailbox user 
after the greeting (bit 064). 
By customizing an FCOS to contain feature bit 004 but not contain bit 005 (Outside caller 
functions and Play outside caller menu prompts, respectively), you can allow knowledgeable 
users to access server functions, while not letting other callers know that the functions are 
available.  
Feature bit 137 (Caller must enter access code) can restrict outside callers from leaving 
messages in high security mailboxes. You set the access codes when configuring each individual 
mailbox. 
You can further ensure the privacy of mailbox users by not putting them in the Dial-by-Name 
database (feature bit 092), or by not allowing the mailbox name or extension number to be played 
(bit 202). This latter feature can be especially important in hotel or dormitory situations.
