I have firmware problem. I'm trying to connect my phone with Asterisk. The connection is ok, but appears on the display strange symbols (euro) and if I make a call, after 10 sec it reboots. 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!

IP Phones do not provide voicemail, that is a function of the PBX it is connected to, either a premise IP PBX or a cloud-based (hosted) PBX. If you are using an Asterisk-based PBX system, the usual way to access the voicemail system is to dial 98 from the phone, however you will need to know the voicemail password.
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.
SPA 941 is a pixel display phone. You can configure it to work with any IP Telephony server like asterisk easily.
1. Press "Paper" Button and press "9". You ll find yourself in network settings. 2. Configure IP address, Subnet mask, Default gateway. 3. Now enter http://ipaddress in your browser 4. Choose EXT1 menu on top 5. Configure the following Proxy: Your server here User ID: Enter the phone number (Mostly they are phone nos.) Password: Enter the password / Secret
Note : depends on your server config you may need to configure some extra informations. Say SIP Port, Preferred Codec, Auth ID etc.
You need to make sure that your laptop and IP phone are on the same network subnet. For instance, if you IP phone's IP address is 192.168.2.24 than your laptop must be on the same network addressing scheme, such as 192.168.2.23.
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!
1. Reset the phone by disconnecting and re-connecting power.
2. When the Nortel logo appears, press each of the four soft keys in sequence.
3. If no other configuration changes are required, press OK repeatedly until the “PC
Port? 1-ON 0-0FF” option appears.
4. Press 1 to enable the PC Port or 0 to disable the PC Port.
5. Select OK to confirm the change.
6. Restart the IP Phone.
When the IP Phone is restarted, the firmware sets the PC Port status accordingly
Try to manually reset the phone - **#"Settings" (this will unlock the configuration) + Network + menu under number "33" - erase the configuration. Then the phone configuration will be erased. Also you can manually set IP address and TFTP server
