20 Most Recent 3Com NBX 2102 IP Phone Questions & Answers

I would recommend starting with what is simple.
Have you tried replacing the Ethernet patch cord that the phone is connected to?
How about the curly cord between the phone and handset?
Does the phone do the same thing if you connect it to a different port?
Does a different phone do the same then when connected where this phone is connected?

The "hands free" button would need to be pushed on the phone you are calling. This will make the phone answer when an internal call comes in to that extension. Outside calls will still act normally and ring the phone, then go to voicemail. the downside is that it is difficult for fellow employees to leave you a voicemail since your phone answers to intercom on all internal calls when "hands free" is pressed. If all you are talking about is paging through the phones, pressing 621 will page through the phones with a 3 digit dial plan and 6201 on a 4 digit dial plan.

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 phones aren't on the system. You have to make sure to turn on "Auto Discover Telephones" under the system settings, system configuration tab within "tab to it" (on 5.0 and older software) and System wide settings, auto discovery with newer software. If the phones are plugged into the same network as the phone system, the phones will automatically come up with extensions.

You have to log in to the phone system as administrator and go to the users tab. You can change it to an unused ext. at that point.

3Com stopped making these phones 4 or 5 years ago. I would suggest contacting the merchant from whom yu purchased them for support.

Run your PC in safe mode. Log in as administrator. Now go to control panel user accounts and change password. Now restart your PC. If Administrator account ask you for the password then you need a password recovery disk http://home.eunet.no/~pnordahl/ntpasswd/

The website you are referring to is your phone systems Web-based management interface.
You need to talk to whoever is managing your phone system and ask them what the new IP address of the system is.

You cannot program a key with an assigned function like tranfer call or conference call, only with the basic button keys can you program it like Key 0 and Key 1.

Reboot the phone system (through the browser) and this should take care of it. There are limited voicemail ports and sometimes they get put on hold and can't be released. I have seen it a lot. some versions of software can clear this but a reboot will take care of it.

This is a Internet Explorer issue. If you use it in "compatibility view" it will show all users when you click on show all users. Otherwise use google chrome or firefox.
