Fixes: How to install a Layer 3 Telephone:

The following is the procedure for installing IP on the Fly to an NBX product:

Make sure to have your license key code ready along with a quantity of IP addresses for the NBX and for your IP Telephones. For every VoIP call, you need two IP addresses: one for the remote IP Telephone, and one for the NBX pool (System Settings/IP addresses) which is for the device you are calling. After you install the license, remember to reboot the NBX to change the network protocol to IP on the FLY under system settings. You also need to assign an IP address range within the NBX as well as an address for the IP Telephone. Assign these after rebooting to IP on the FLY under IP Settings.

• 1. Install your license, then change protocols to IP on the Fly under System settings

• 2. Reboot the NBX to set the changes

• 3. Add your range of IP addresses under system settings/IP addresses for IP on the Fly.

• 4. Install your telephones along with an IP address

Note: If using DHCP, then the server will automatically assign an IP address for each new telephone thus, add one per device).

• 5. Once the telephone is discovered, then it should be operational at this point.

IMPORTANT NOTE: Make sure:

- Your data switch has IGMP disabled and your Router has IGMP enabled - UDP ports 2093 thrum 2096 are open - TCP IP port 1040 is open - Browser port 80 is open

The NBX uses Unicast, Multicast, and Broadcast packets. If you cannot page, or conference, then check the settings above to make sure they are correct on your switches and /or Routers.

Prerequisites:

1. Make sure the telephone set has been initially attached to any NBX 100 system with the latest version of software installed. This is to insure that the telephone has the correct IP enabled software downloaded from the NBX 100 system.

Recommended: You might want to install the system on one version back (R4.0.27) and then upgrade to the newest (R4.1.21) as this will allow you to have a back up database and a version to back rev in case your system has a problem. For example, a faulty Hard Drive.

2. If the telephone set you are attempting to program the IP information is already attached to a NBX 100 system, please detach it from the system (ethernet cable) at this time and cycle power by removing power from the telephone set and reapplying power to the telephone set.

3. Ensure that there is an available IP address for this telephone set, also be certain that there is enough bandwidth to place this phone over a DSL, Cable Modem, Frame Relay, etc? Minimum bandwidth 56k, 64k preferred.

4. NBX 100 telephone sets are DHCP clients and there is no need to program IP in such settings, however the NCP (Network Call Processor) IP still needs to be programmed in the telephone set. Option 184 can be used to allow the DHCP server to provide the NCP IP address.

5. Firewalls (with default configuration) do not allow NBX telephone sets to find the NCP remotely. The Firewall needs to be configured to allow telephone sets to enter the corporate (internal) network to properly connect to the NCP (Network Call Processor).

To configure IP on your NBX phone:

1. Unplug phone from network and reset power to phone, wait until basic bootup is finished.

2. Press the Program key and scroll using the up and down arrow keys right of the display.

3. The first lower right corner button with LED (light emitting diode) displays the current IP address. Use the key pad and the left and right buttons under the display to enter the IP address then press the # pound key this is to accept. If you make a mistake while entering IP information use the oval keys under the LCD (liquid crystal display) to reposition the cursor. The outer keys will move the cursor left and right.

4. Press the Program key twice until the LCD displays the programming menu.

To set the Subnet Mask:

1. Press the 2nd button from the lower right corner of the telephone set ( See below for a template of the telephone with the button layout)

2. Enter Subnet mask and press the # pound key to accept. For example: 255.255.255.0, #

3. Press the Program key twice until the LCD displays the programming menu.

To set the Gateway:

• 1. Press the 3rd button from the lower right corner of the telephone set
• 2. Enter Gateway address and press the # pound key. For example: 192.168.1.1, press 192 168 001 001 and then the # (pound sign)
• 3. Press the Program key twice until the LCD displays the programming menu

To set the NCP (Network Call Processor) IP:

• 1. Press the 4th button from the right lower corner of the telephone set
• 2. For example: 24.1.179.70, enter: 024 001 179 070 and then the pound sign #
• 3. Press the Program key twice until the LCD displays the programming menu

The default MAC address should be set to ff:ff:ff:ff:ff:ff. This forces the telephone set to automatically obtain the MAC address of the NCP. Otherwise proceed with the following steps to manually program the NCP MAC address in to the telephone set. Typical, it is not necessary to program the NCP MAC into the phone unless for troubleshooting purposes or in the cases of multiple NBX NCPs on the system

To set MAC (Media Access Control) Hardware address:

NOTE: The phone will automatically obtain the NCP MAC address when both are connected to the same LAN.

• 1. Obtain the NCP MAC address from NetSet> reports> system data
• 2. Make sure you that the phone is in programming mode
• 3. Press the oval key under the Program key
• 4. Start entering the MAC address. For example, 00:e0:bb:00:1c:80 (every chassis has a unique MAC address)
• 5. To enter Alphabet in the telephone set use, the oval keys under the Program key. There are 6 oval keys, from top to bottom are the letters A-F, ABCDEF
• 6. Press the # (pound) key to accept the MAC address
• 7. Press the Program key once and wait for the phone to reboot itself, wait until the telephone set has been auto discovered by the remote NBX 100 system.

A new extension number appears on the display, which is an indication of your successful VoIP implementation.

The NBX communication protocol normally cannot work with NAT because private IP addresses assigned to phones local to the NCP to enable communication with the (public) IP Phone do not pass out through the router translation table. This means that when the remote device attempts to send IP datagrams directly to this private IP address they will not pass out though the local router. The phone local to the NCP is given the correct public address for the far end device, so the result is one way communication. Which means that only the remote (public) side will hear audio; the local (private) side will get no audio.

Remote IP phones lose statically assigned IP addresses and/or take DHCP addresses instead

This condition is the result of a caveat in using NetSet . It becomes apparent on systems running in IP Serve or IP On-The-Fly Mode (in all versions up to NBX R4_0). This affects ALL DEVICES, even devices functioning at layer 2 on the NBX local segment.

When you enter the “IP SETTINGS” screen (actually ANY “modify” screen) from the Device Configuration section to view IP information for any given device, exiting the screen by pressing the “OK” button causes the system to reapply all IP values in the “Manually Assigned” section, and to reboot that device. On all NBX configuration screens, “OK” means “Apply and Exit”. So pressing OK Applies the manually assigned settings and reboots, even though you may not have intended this. Always press “CANCEL” on any screen unless you intend to update the device with the settings shown in that screen.
