USER CONFIGURATION
This chapter describes these elements of the NBX system:
■Users (including phantom mailboxes)
■Call Pickup
■Hunt Groups
■Class of Service (CoS)
UsersYou use the User Configuration tab in NBX NetSet utility to add users and 
phantom mailboxes to the NBX system and remove them. You can also 
modify and maintain user profiles and parameters.
To perform these tasks, in the NBX NetSet utility, select User 
Configuration > Users and then see the Help for these buttons: Add, 
Modify, Remove, and User Settings. For more information about User 
Settings, which individual users can also configure, see Chapter 1 in the 
NBX Telephone Guide.
Phantom MailboxesYou can add a mailbox for an extension that has no associated physical 
telephone. A caller can dial directly into a phantom mailbox, the person 
assigned to the phantom mailbox can create and send a message from 
within the voice mail system, and the Auto Attendant can route voice 
messages to the phantom mailbox.
Example: A user who travels frequently or who is never in the office can 
use a phantom mailbox to receive and manage messages, even though 
no telephone is associated with the mailbox extension.
The user of a phantom mailbox can call in to the Auto Attendant to 
retrieve and send messages, log into the NBX NetSet utility to manage 
messages, including having the system forward voice messages using the 
Off-Site Notification feature, or use an e-mail client to manage the 
messages (see “IMAP (for Integrated Voice Mail)”
 in Chapter 6). 
						

							324CHAPTER 4: USER CONFIGURATION
Call PickupIn some organizations, it can be useful if any user who hears a telephone 
ringing can pick up the call on her or his own telephone. 
Using the Call Pickup feature, you can create one or more Call Pickup 
groups to allow this convenient sharing.
Group NumbersPickup group numbering differs for SuperStack 3 NBX systems and NBX 
100 systems.
SuperStack 3 NBX systems:
■50 Call Pickup groups:
■Group 0 through group 31 (extension 500 through 531)
■Group 32 through group 49 (extension 482 through 499)
■50 Directed Call Pickup groups (extension 540 through 589). 
NBX 100 systems
■32 Call Pickup groups from group 0 (extension 500) through group 31 
(extension 531)
■10 Directed Call Pickup groups from 540 through 549.
See the Phone Guide for user instruction on how to use Call Pickup.
If you select Auto Add Phones to Call Pickup Group 0 (System Settings > 
System-wide), every telephone that is added to the system is a member of 
Call Pickup group 0. Administrators can add and remove users to and 
from any of the groups. Users can remove themselves from Call Pickup 
group 0, but not from any other Call Pickup groups.
Calls to a user who is a member of default Call Pickup Group 500 can be 
picked up from any telephone. Users can add or remove their own 
telephone extensions from Group 500 to allow or prevent others from 
picking up their calls. See the NBX Telephone Guide and the User Help.
You can map Call Pickup Groups to user telephone buttons to provide 
one-touch access to the Call Pickup groups. See “Creating and Managing 
Button Mappings” in Chapter 3.
To modify call pickup groups, select User Configuration > Call Pickup. See 
the Administrator Help for procedures on modifying call pickup groups. 
						

							Hunt Groups325
Hunt GroupsA hunt group is a set of users. A call that is routed to a hunt group can 
reach any member of the group who is currently logged into the group. A 
static hunt group is one in which all members are permanently logged in 
(locked). In a dynamic hunt group, users can be logged in and out of the 
group by you, the administrator, or you can allow them to log into or out 
of the group themselves, using the group password you create.
Hunt groups are specified by extension, in these ranges:
■SuperStack 3 NBX: 4000–4099 (All 100 can be assigned.)
■NBX 100: 450–499 (A maximum of 30 can be assigned.)
To configure hunt groups, select User Configuration > Hunt Groups in the 
NBX NetSet utility and then see the Help topics associated with these 
buttons: Add, Modify, Remove, Status, and Feature Mappings.
Hunt Group
Considerations
■For a telephone to participate in a hunt group, the user must be 
logged into the hunt group. See the NBX Telephone Guide.
■When you create a hunt group, you specify one of three types: linear 
hunt group, circular hunt group, or calling group. Your choice is 
based largely on the ringing pattern that you want. 
■For each group that you define, you also specify:
■The To t a l  T i m e o u t — The length of time in seconds that the call 
will ring on the group’s telephones before the call goes to the 
group’s call coverage point.
■The Per-Device Timeout — The length of time in seconds that 
each phone rings in the cycle. (Ignored for Calling Groups.)
■Whether you want the system to log a phone out of the hunt 
group if it does not answer. (Ignored for Calling Groups.)
■For linear and circular hunt groups, the order in which a group 
telephone rings (the telephone’s “priority”) is the same as the order in 
which you added it to the group. For calling groups, all phones ring 
simultaneously.
Linear and Circular
Hunt GroupsIn linear and circular hunt groups, calls ring sequentially on telephones in 
the group, but the behavior differs when the time specified in the Total 
Timeout field elapses:
■If the Total Timeout value is less than the sum of all of the Per-Device 
Timeout values, a call that is routed to either a linear and circular hunt  
						

							326CHAPTER 4: USER CONFIGURATION
group rings on some, but not all of the telephones in the group and 
then is routed to the group’s call coverage point.
■If the Total Timeout value is greater than the sum of the Per-Device 
Timeouts:
■For a Linear Hunt Group, the call rings in order on each group 
telephone and then goes to the group’s call coverage point. Any 
time remaining in the Total Timeout is ignored, and the call does 
not ring again on any telephone in the group.
■For a Circular Hunt Group, the call rings in order on each group 
telephone and then, for the remainder of the Total Timout, begins 
ringing again through the telephones, in order. Depending on the 
Total Timeout value, an unanswered call may ring through all 
telephones in the group multiple times.
If the Total Timeout value exactly matches the sum of the Per-Device 
Timeouts, the behavior of a single incoming call is the same for both 
linear and circular hunt groups.
When a second call is routed to a linear or circular hunt group, the 
telephone on which the second call first rings is different:
■For Linear Hunt Group, the new call rings on the first telephone in the 
group.
■For a Circular Hunt Group, the new call rings on the telephone that is 
next in the ringing sequence.
Calling GroupsIn this special type of hunt group, an incoming call rings on all telephones 
in the group simultaneously. After the Total Timeout value is reached, a 
call that is still unanswered is routed to the group’s call coverage point. 
The value in the Per Device Timeout field has no effect on the behavior of 
telephones in a calling group.
Call CoverageFor each type of hunt group, use this set of check boxes to define where 
the NBX system routes an unanswered call (the call coverage point):
■Voice Mail — An unanswered call goes to the hunt group’s voice 
mailbox (which is separate from the voice mailbox of any telephone 
that is a member of the group).
■Auto Attendant — An unanswered call goes to the Automated 
Attendant that you specify. 
						

							Class of Service (CoS)327
■Phone Number — An unanswered call goes to the extension number 
that you specify in this field. Examples: The receptionist’s telephone, or 
the extension of another hunt group.
Class of Service 
(CoS)Class of Service (CoS) is a set of calling permissions that you assign to 
users. Most permissions are subject to the Business Hours parameters: 
Open, Closed, Lunch, and Other. For example, you can create a class 
where toll calls are allowed during normal business hours (Open), but are 
not allowed after business hours (Closed). 
Additional considerations:
■Emergency calls (such as calls to 911) are not subject to CoS 
restrictions. 
■System-wide Speed Dial numbers are not subject to Class of Service 
restrictions. For example, if you want to enable calling to a specific toll 
number to all users without regard to their CoS settings, create a 
System Speed Dial for that number.
■When you create a new profile, the system assigns the default CoS 
unless you specify a different one. If you edit the properties of the 
default CoS, verify that it contains a minimum set of permissions.
■You can enable or disable Offsite Notification at the system level. The 
system-wide setting takes precedence over the CoS setting.
Service classes control these types of calls:
■Intercom 
■External (local, long distance, international, long distance toll-free, 
and long distance toll) 
■CO Code (optional telephone company services, such as Call Waiting)
■Trunk to trunk transfers
■Off-site Notification
To configure Class of Service, select User Configuration > CoS and see the 
Help screens for these buttons: Add, Modify, Remove, and View.

Software VersionThe call control software for the NBX system.
System Serial #The serial number on the Call Processor circuit board.
Host NameThis is an IP setting. It is a name you can give to the NBX 
system so you do not have to specify the IP address when 
accessing the NBX NetSet utility through a browser. A host 
name works only if you add the name to the name 
resolution system. If you do not use a name resolution 
system, you must specify the IP address in the browser. 
IP AddressThe IP address of the NBX system.
Default GatewayThe IP address of the destination host for any IP packet not 
addressed to a host on the local subnetwork.
Subnet MaskAn IP setting that identifies the network and host portions 
of an IP address on the network.
Network ProtocolThe transport mechanism for voice packets.
Ethernet only: All communications are at the Ethernet 
frame layer.
Standard IP: IP communications are used for traffic 
between NBX system addresses. Every device needs an 
IP address.
IP-On-the-Fly: An implementation of IP communications in 
which Layer 2 (Ethernet) devices are temporarily assigned a 
Layer 3 (IP) address only when they need to communication 
with a Layer 3 device on a different subnetwork. The IP 
address is assigned from an address pool defined by the 
NBX system administrator. After the Layer 2 device returns 
to the idle state the IP address is returned to the pool of 
available addresses for future use.
MOH MAC AddressThe hardware address of the Music-on-Hold device.
Free MemoryAvailable memory on the NBX system.
Date and TimeThe current system date and time. To modify, click the Date 
and Time button.
