System Settings331 Table 51 System Settings System-wide Dialog Box Fields FieldPurpose Host NameAn IP setting for the NBX system. A Host name functions only if you add the name to the name resolution system. If you do not do this, then you must enter the IP address in the browser when you want to access the NBX NetSet utility. SMTP Domain NameThe name of your SMTP domain. Required for Off-Site Notification by e-mail. 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. Primary DNSThe IP address of the primary DNS server. You must specify at least a primary address to use e-mail Off-Site Notification. Secondary DNSThe IP address of the secondary DNS server. If you specify two DNS IP addresses, they must be the primary and secondary addresses. Tertiary DNSThe IP address of the tertiary DNS server. 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. NOTE: Every device needs an IP address. IP communications are optional features of the NBX system and require separate licensing. 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 communicate 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. If you have the appropriate license and select IP On-the-Fly in the Network Protocol list, you must return to the Current System Settings window, select IP Addresses and add the IP addresses associated with IP-on-the-Fly. There may be unpredictable results in other system functions if you have Network Protocol set to IP-on-the-Fly but do not have any IP telephones or addresses.

Turn this ON before Auto Discovering telephones if you want the telephones to appear in Call Pickup Group 0. Table 51 System Settings System-wide Dialog Box Fields (continued) FieldPurpose
System Settings333 Handsfree on Transfer(Affects NBX Business Telephones only) This setting governs the way an NBX Business Telephone responds to a transferred call when a user enables the HANDS FREE button on the telephone or uses the HANDS FREE feature code (100). Transferred calls include: ■Internal calls from other NBX users, both direct and transferred ■External calls transferred via an automated attendant NOTE: Calls that directly arrive at the NBX Business Telephone via an analog telephone line or Digital Line Card channel ring on the telephone in the normal way. To answer the call, the user must either pick up the handset or press the Speaker button. Handsfree on Transfer Enabled When the HANDS FREE button on an NBX Business Telephone is activated and the Handsfree on Transfer function is enabled on the NBX system, a call that is transferred to the telephone causes the telephone to issue a two-second hands-free warning tone. The telephone user does not need to take any action to answer the call because, immediately after the warning tone, the call is connected using the speaker phone. Handsfree on Transfer Disabled When the HANDS FREE button on an NBX Business Telephone is activated but the Handsfree on Transfer function is disabled on the NBX system, a call that is transferred to the telephone ring in the normal manner, whether or not the HANDS FREE button is activated. Internal calls cause the telephone to issue a two-second hands-free warning tone. The user does not need to take any action to answer the internal call because, immediately after the warning tone, the system connects the call using the speaker phone. If an external call is blind transferred manually to the NBX Business Telephone, the call rings on the telephone in the normal manner and the HANDS FREE button is ignored. Virtual LAN EnabledAdds a Priority 6 Virtual LAN identifier to each Ethernet frame. Virtual LAN IDIf the VLAN Enabled box is checked, you must add the Virtual LAN identifier in this field. Table 51 System Settings System-wide Dialog Box Fields (continued) FieldPurpose
334CHAPTER 5: SYSTEM CONFIGURATION Regional SettingsAfter you install regional software and components from the regional packs, you can enable regional settings. To enable these regional settings in the NBX NetSet utility, you select the appropriate country and language for the system voice prompts, the technical tones and cadences, and the online user documentation. To enable regional settings, select System Configuration > System Settings > Regional Settings. See the Help for the procedure on enabling regional settings. See “Regional Software” in Chapter 7 for information on installing regional packs. IP VLAN Tagging EnabledIf you enable the IP VLAN Tagging Enabled check box, the NBX system VLAN tags outgoing voice and control packets intended for devices on the VLAN you specified in the Virtual LAN ID text box. System-wide CLIRSuppresses the transmission of caller ID for outgoing calls. Music On Hold Enables Ethernet multicasts for Music On Hold (MOH). MOH is automatically enabled if Music on Transfer is enabled. MOH Audio should be enabled only if you have a MOH device connected to the system. Music on TransferEnables MOH audio for Call Transfer; requires MOH to be installed and enabled. Music on Transfer is automatically disabled if MOH is disabled. One Button TransferEnables system users to transfer a call by pressing the Transfer button only once. If this box is not checked, call transfers require users to press the Transfer button once to start the call transfer and another time to complete the transfer of the call. NBX MessagingAllows you to enable or disable NBX Messaging after you install a third-party messaging license. By default, this checkbox is selected but not accessible until you install a third-party messaging license. If you disable NBX Messaging by clearing this checkbox, all NBX Messaging icons and headings become inactive throughout the NBX NetSet utility. Third-Party MessagingThis check box is active only if you have installed a third-party messaging license. You can enable the third-party messaging application by selecting this check box or by clearing the NBX Messaging check box. Pulse DialingEnables pulse dialing for all telephones in the system. Table 51 System Settings System-wide Dialog Box Fields (continued) FieldPurpose
System Settings335 Advanced Regional Settings The NBX system also allows you to choose different regional settings for the system voice prompts, the technical tones and cadences, and the online user (not administrator) documentation. For example, you may require local tones and cadences but may want the documentation to be in English and the voice prompts in Australian English. You can select separate regional settings for: ■Voice prompts — The Auto Attendant voice prompts. ■Documentation — The NBX Telephone Guide, the User Help, and the quick reference cards. ■Tones and Cadences — The tones and the patterns of rings (cadence) versus silence. Tones and cadences vary from country to country. Examples: ■United States ringing cadence (pattern) is 2 seconds of ring followed by 4 seconds of silence. ■United Kingdom ringing cadence is 2 rings within approximately 2 seconds followed by 2 seconds of silence. ■United States busy tone is 0.75 seconds of tone followed by 0.75 seconds of silence. To enable different regional settings, select System Configuration > System Settings > Regional Settings > Advanced. See the Help for procedures on selecting multiple regional settings. Date and TimeIf necessary, you can set the NBX system date and time. It is important that the date and time are accurate because the system date and time: ■Appear on an idle NBX telephone display ■Affect business hours behavior ■Affect time-dependent prompts in the Auto Attendant ■Affect the time and date stamp on voicemail To select the system date and time, select System Configuration > System Settings > Date and Time. See the Help for the procedure on setting the system date and time.
336CHAPTER 5: SYSTEM CONFIGURATION TimersSystem timers enable you to set time-out periods for the NBX system features that are described in Table 52 . To set timers, select System Configuration > System Settings > Timers. See the Help for the procedure on setting timers. Ringing PatternsYou can set system-wide ringing patterns to distinguish between internal and external calls. You can choose one, two, or three rings to distinguish between internal and external calls. Do not confuse ringing patterns with ringer tones, which NBX system users can set for their telephones using the NBX NetSet utility. For information on setting a user’s ringing tones, see the NBX Telephone Guide or the User Help. To set ringing patterns, select System Configuration > System Settings > Ringing Patterns. See the Help for instructions. Table 52 System Timers Fields FieldPurpose Forward Voice Mail On TimeoutWhen a telephone’s FWD VMAIL button is enabled, this field specifies the duration of ringing before a call is forwarded to voice mail. If you set this time to under 6 seconds, caller ID information is not captured in voicemail. Forward Voice Mail Off TimeoutWhen a telephone’s FWD VMAIL button is disabled, this field specifies the duration of ringing before a call is forwarded to voice mail. Line Port Hold TimeoutFor a call originating on an outside line (Analog Line Card port), the length of time that the call remains on hold before it rings at the extension that placed the call on hold. Call Park TimeoutThe length of time that a call can be parked before it rings at the extension that parked the call. Conference TimeoutThe length of time before a conference attempt is abandoned. Applies to a blind conference only. The timeout takes effect under these conditions: ■Two people, A and B, are involved in a call and one of them attempts to blind conference another person, C. ■C does not answer and C’s voice mail does not pick up the call. After the Conference Timeout period, the system stops ringing C’s telephone, stops attempting to conference with C, and reverts to the call between A and B. Transfer TimeoutThe length of time that a transferred call attempts the transfer before it rings back to the caller’s extension.
System Settings337 Multicast AddressesThe NBX system uses IP multicast addressing to distribute information for these system features: ■Mapped line appearances ■Music on hold ■Internal page ■External page ■Conference calls These features are available on Layer 2 and Layer 3 IP devices. The IP implementation uses Internet Group Management Protocol (IGMP) to transmit and distribute the necessary data and audio. If you configure your NBX system to use IP On-the-Fly or Standard IP and your switches use IGMP Snooping, you must have an IGMP Host on the network. Typically, an IGMP Host is an IP Multicast Router or a switch that has IGMP Query capability. The NBX system IGMP is an implementation of administratively scoped IP multicast that uses three scopes of administration: ■Local scope — Limited by local routers with IP addresses 239.255.0.0 through 239.255.0.16 ■Organizational local scope — Limited by boundary routers with IP addresses 239.192.0.0 through 239.192.0.14 ■Global scope — IP addresses 224.2.0.0 through 224.2.127.253 IGMP may not be available in all systems or network topologies. All of the routers between the various components must support IGMP and the necessary router protocols to establish a path for the IP multicast packets. Each event that occurs in an IGMP setup, such as taking a telephone off the hook, causes a packet of 200 Kb to 300 Kb to be sent. The default settings for the IP multicast addresses should work in most network environments. Certain addresses are reserved. The MAC address and the IP address displayed on any one line of the Multicast Address List window are not related.
338CHAPTER 5: SYSTEM CONFIGURATION There are two methods for selecting multicast addresses: ■Change IP — Lets you select a starting address for all entries. Changing IP multicast addresses is a quick way to change the range of NBX system multicast addresses, to avoid conflicts with other equipment on your network. ■Change bins — Lets you change a single entry by selecting from a list of available bins. Changing IP bins is useful for changing a single address that may conflict with another system device. Consult your network administrator to determine which address is in conflict and the new address to choose. To change multicast addresses, select System Configuration > System Settings > Multicast Addresses. See the Help for instructions. IP AddressesThis window allows you to add or delete a range of IP On-the-Fly addresses. Select System Configuration > System Settings > IP Addresses to perform these functions. See the Help for the procedure on adding or deleting IP addresses. The IP Addresses button appears only if you have IP On-the-Fly enabled in System Configuration > System Settings > System-wide. Maintenance AlertsIf you have a SuperStack 3 NBX system with disk mirroring or dual power supplies and with NBX Messaging enabled, you can: ■Configure maintenance alert voice mail messages so that they appear to come from one NBX system user. ■Designate up to 15 NBX system users to receive maintenance alerts. Alert messages are defined by the NBX system. The content depends on the cause of the alert. When a user receives a maintenance alert message, the source of the message depends on whether you have configured an NBX system user as the author of maintenance alert messages. See Table 53 for details. Table 53 Source of Maintenance Alert Messages Message TypeAuthor ConfiguredNo Author Configured Local Voice Mail MessageThe configured system user is announced as the sender of the message.An outside caller is announced as the sender of the message.
Speed Dials339 See the Help for the procedures on setting the maintenance alert author and specifying users to receive maintenance alerts. Speed DialsYou can create up to 100 System Speed Dial numbers. You can also create system speed dial and personal speed dial button definitions and assign them to groups. Any telephone in a group has access to the same button definitions. Users can create personal speed dial definitions for buttons that do not already have a button mapping. Users can also change definitions for any buttons mapped as personal speed dial buttons, even if those buttons are defined in the Group Button Mappings. System speed dial numbers are not subject to Class of Service (CoS) restrictions, so a speed dial number mapped to a number that is a toll call is available to users even if their CoS does not allow toll calls. Personal speed dial numbers are subject to CoS. Do not confuse speed dial codes with extension numbers. To set up system speed dials, select System Configuration > Speed Dials. See the Help for these speed dial procedures: ■Adding or modifying a system speed dial ■Removing a system speed dial ■Printing system speed dials Business IdentityYou can configure information about the your business, such as business address and business hours, including time of day service modes. You can also view the current system mode and force the system into a different mode. Offsite E-mail MessageThe name of the configured system user appears in the From field of the e-mail.The From field in the e-mail contains the word anonymous. Offsite Voice Mail MessageThe system user is announced as the sender of the message.An outside caller is announced as the sender of the message. Table 53 Source of Maintenance Alert Messages (continued) Message TypeAuthor ConfiguredNo Author Configured
340CHAPTER 5: SYSTEM CONFIGURATION To enter business information, select System Configuration > Business Identity. See the Help for procedures to modify these types of information: ■Business information ■Business hours ■System mode Business InformationYou can enter basic information about your business on this dialog box, including name, address, and telephone and Fax numbers. Business HoursThe business hours dialog box allows you to define business hours for three separate times of day, or service, modes: Open, Lunch, and Other. Any time period that does not fall within these specified hours is considered Closed. Business hours are directly linked to time-of-day service modes and can affect other settings in the system, such as the Auto Attendant. You can manually specify that the system operate in a given mode, or set it to operate automatically. See “System Mode” later in this chapter. If the system is left in an automatic state, it constantly compares the current time of day and day of week with the business hour tables. The system knows the current day of the week and proceeds across the tables in a sequential manner, looking for business hours that match the current time of day. The system examines the three tables sequentially: first the Other mode, then the Lunch mode, and then the Open mode. The system moves across the tables until it finds a match.It skips a blank table. System ModeYou can manually specify that the system operate in a given mode, or set it to operate automatically. If necessary, you can force the system into a specific Time of Day Service mode without having to reconfigure other system settings, such as Business Hours. If the system is left in an automatic state, it constantly compares the current time of day and day of week with the business hour tables. SecurityThe Security function enables you to set system passwords, including the administrator, Auto Attendant, and reporting passwords.
