Question about 3Com NBX 3102 IP Phone

Open Question

We have 15 group 2 licenses and only 3 group 2 phones in use yet our NBX System will not allow a 3102 phone to load. It keeps changing the 3102 to an "NBX Business Phone" so we can't properly map the buttons. Why does it do this?

If the phones are only 6-8 months old you should be calling 3Com. those phones have a 1 year warranty and once you register them they will help you troubleshoot and replace them if needed. Can you provide more detail? Do you have any network issues while this is happening? Does speakerphone work but the handset doesn't?

Add the NBX's IP and mac address to phone. Also static it on the same subnet.
It will go through about three long reboots.
If it doesn't work change the NBX to anything but "ethernet only" and reboot it. Then reboot phone with the above settings.

Default gateway

Depending on the mode the phone is in, it may be only a layer 2 device - meaning it just broadcasts at layer 2 to find the NBX and once discovered, uses layer 2 for all communication.

Web page + 3102

You can't web to a 3102 phone, only the phone system. If you don't know what the IP address is on the phone system, you will have to get a serial cable (null modem cable) DB9 male to DB9 female and connect to the console 1 of the phone system. You will need a terminal emulator program and connect at 9600, 8, none and 1 for the settings. Type nbxIpConfig (case sensitive) and hit enter. The IP address will then be shown. If this is not what you were asking, please explain.

What's the number for customer service for 3com

3Com was purchased by HP and has discontinued the NBX product line and support. They have also as of September 31, 2013 stopped selling licenses. Some resellers are still able to get them but I'm sure that will stop soon enough. The NBX tech support number I had was for tech support is now a prize hotline number.

I am getting the following message trying to reset button mappings on a 3C1022 phone. The phone is part of a phone group with unlocked buttons. "unable to save changes.Invalid data has been entered...

You need to go to the Telephone group button mappings and click on the lock next to the buttons you want to change. Once you unlock it for the group that the phone is in, you will be able to change it for that phone. Keep in mind that this also allows the other users in that telephone group to change their buttons too.

The sytem says its waiting for NCP and has the NCP light light. How can I reboot or fix the problem

This means that the phone and the NCP (Network Call Processor) in the phone system aren't communicating with each other. Multiple problems can cause this. Things to check:
1. Network cable - Is it plugged in, and to the right port?
2. Phone died
3. Is there an available license? (3100 series phones)
4. Is there a network switch problem causing a loss of communication through whatever switch that the phone is plugged into.

Do you have experts in the 3com nbx 100 system?

sorry to say, but you have to contact your landline operator for this since it doesn't depend on the type of phone you have connected to it

Cant connect additional 3102 to nbx. Please help!

3102 phones require group 2 licenses purchased from an authorized NBX reseller. if you don't have enough the system will not allow the phone to be discovered. You can check this unler the licenses tab while logged into the phone system as administrator.

Roll back phone software

The phone is in a continuous because it is trying to connect to the NBX. You need to make sure it is on the same network as the NBX. Also, within the NBX you need to make sure Auto-Discovery is enabled. You also need to check how many group 2 licenses you have, as this phone requires one to run on the NBX.
