IP 7920 & Asterisk

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.

Asterisk Users 3Com Phones

SPA 941 is a pixel display phone. You can configure it to work with any IP Telephony server like asterisk easily.

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

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!

Hi.

It would be best to download a new installer and reinstall the program.

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.

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

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.

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
