Are you using a PBX system ? you can block your number the same way you would with other phones. if you have to dial a number before you can get an outside line, the dial the code after,. usually *67

    Check if your phone provider offers telephone call screening service that allows you block specific area codes or phone number. The service though comes with a fee.

I want to block all incoming calls except the one in contacts, is this possible ?

Not sure on a Nokia but on an iPhone you use the Do Not Disturb setting. It only lets calls ring from those in Contacts or Favourites.

Default Password is 0000 or 00000000 or Reboot into previous version and change password to an alphanumeric password The word "administrator" has to be entered as the User Name. this pdf could help ( and this pdf will tell you how to update the machine to a newer version or if it is in the newest version you must downgrade it just folow the instructions on this pdf ( or you could try and Connect a PC to the console port of the NBX (9600 baud, 8 data bits, 1 stop bit, no parity)1. All commands are case sensitive. At the NBX or SS3 Prompt type nbxDb. NBXs response- DBITEST (? for help):
2. At the DBITEST prompt type X.NBXs response-encrypted admin pass ---> (!Ofm0uealStEsrx1) 3. Contact 3Com Tech Support to have the password decrypted. if you have anymore problems i would be happy to help and if you cant fix it still i would be happy to do it for you for a small fee ..i hope this helped and i look forward to hearing from you

I have a bad phone on an NBX100. How do I swap out the phone with a new one and keep all of my programming for the existing extension

What software version are you running? Specifically 5.0.x and below or 6.0.x and above? Assuming you have plugged in the new phone and have discovered it on the system... If you know how to get to the users tab for either version, then select the users extn (example ext.100) and click modify(5.0) or on the extn number (6.0). Then scroll down in the section on the right where it says telephone list (5.0) or associated telephone (6.0) and select the newly added phone (example ext. 101). Once you select the new extn (101) and click ok or apply, you will have moved their user profile to the new phone. All of their recordings, passwords and voicemails will move with the profile.

I am looking to find out if it is possible to block just one numbers' incoming calls on the Nokia 6085? I can see that I can "Bar all incoming calls" on the security settings, but i only want to block one...

"Call barring" isn't possible from your phone, it can only be access/set from the Network operator, if you really have problem, please call the customer care of your network operator, tell them your problem, they'll provide you the call barring code and will instruct you how to set it.
Good luck.
Thanks for using FixYa.

How do you set a 3Com v3000 R6_0_63 to block certain inbound caller numbers?

That needs to be done at the carrier level (AT&T, Verizon etc...). With a PRI you can do a little bit of routing the numbers you want to block to an bad destination but it isn't easy for most people to do as you need to be comfortable with the dial plan.
