Now, where can I find a way to update my phone? I searched everywhere but I didn't find anything...only link with no file to download.My version of firmware is:7920.3.3-01-03 Please help me!Thank you

I believe I saw somewhere that the 7920 works best with the 4.02 version of firmware... only hitch is you can't get it unless you have a valid Cisco login with access to their voice stuff. You could see if your local partner could get it for you otherwise. Also, I think you need the cradle to upgrade the phone manually - otherwise you need a TFTP server set up and the proper keywords in the cnf.xml file. There is better info on voip-info.org about these sccp phones - god I wish they (Cisco) would release a SIP firmware for these things!

3COM 3100 entry phone, how to configure SIP


From Digium Mailing List:

3Com 3100 series phones do not support SIP with non-3Com systems. They have a basic boot loader which must download code from a 3Com NBX or a 3Com VCX system. If you don't have either of these, then you won't get runtime code on the phone, thereby making it impossible to use the thing with Asterisk.

You can't. The 1100 and 2100 series 3Com phones aren't SIP phones. Only the 3100 series phones can be used.

Can I use a CISCO IP 7941 phone, that has been on a company network, in my home? Should it just work by plugging in a telephone connection and using the appropriate power supply? Is there programming that...


Yes, there is programming which would need to be removed. However, you would need a cisco call manager($800) at home. Unless of course you have voip in your home. then you could just set it to DHCP I'm assuming and then it should just work!

How To Unlock Tesco Internet Phone Siemans DP450

Unlock your Tesco DP450 IP Phone to use this with other VoIP providers.
Gigaset Communications have created a process that enables Tesco Internet Phone subscribers with Siemens Dual-Phone DP450 to unlock the phone from the Tesco Internet Phone service. This will enable the phone to be used with other Internet Telephone services. This follows the recent news that the Tesco Internet Phone service is to be ceased from April 26th, 2010.
This is an approved method for unlocking the Siemens Dual-Phone DP450 defined and released by Gigaset Communications, the original supplier of the phone to Tesco. If this procedure is not followed exactly your phone might not work anymore. In this case Gigaset Communications cannot accept any warranty claims.

Unlock procedure
Your Phone should have the latest released Tesco software version, else this unlock procedure will not work.

On your handset:

BASE > SETTINGS > SOFTWARE UPDATE
Select and press OK Enter the system PIN (0000) and press OK
The base station establishes a connection to the internet or a local PC.
YES Press the display key to start the firmware update. If no update is needed, this will be displayed.

To unlock the WEB interface of the DP450, you need to enter the following service code. Please use the exact code as is described below, else your phone will not work anymore.
SETTINGS > BASE 94762001 (Now "Eeprom" must be displayed)
Insert the following number sequence: 01778 06183 06191 Press OK to finish the programming. "Saved" must be displayed on the Handset.

Then release the phone to be able to upgrade it with the latest Retail firmware version.
SETTING > BASE 94762001 (Now "Eeprom" must be displayed)
Now insert this number sequence: 04850 04351 04864 Press OK to finish the programming. "Saved" must be displayed on the Handset.

After this procedure you can upgrade your phone to use the latest retail firmware version.
SETTINGS > BASE > SOFTWARE UPGRADE
Select and press OK Enter the system PIN (0000) and press OK
The base station establishes a connection to the internet or a local PC.
YES Press the display key to start the firmware update.

Please Note: The firmware update can last up to 3 minutes.

Your Phone is by default configured to use the Internet Telephone service, if you want to change this to set the default to the land line you need to change this in the web interface from your phone. How to do this, download the Gigaset S450 IP manual from the Gigaset web-site URL: http://gigaset.com/uk/en/cms/PageCustom ... nuals.html

Reseting to default Firmware!!!


If you are saying that there is a mistake with the firmware, you are in serious trouble. Firmware in most cases cannot be restored if there is a problem with upgrades or installs.
